The seasons are the results of the earth's
- A.
Rotation on its axis and revolution around the sun
- B.
Varying distance from the sun
- C.
Revolution around the sun and inclination of its axis.
- D.
Varying distance from the planets of the solar system.
Correct Answer
C. Revolution around the sun and inclination of its axis.Explanation
The seasons are caused by two factors: the earth's revolution around the sun and the inclination of its axis. The earth's revolution around the sun causes the changing position of the sun in the sky, which leads to variations in the amount of sunlight received in different parts of the earth throughout the year. The inclination of the earth's axis causes the tilt of the earth, which results in different angles of sunlight reaching different parts of the earth during different seasons. Together, these two factors determine the changing seasons.Rate this question:

Typical summer storms or showers in tropical and continental climates are a type of ________ precipitation.
- A.
Orographic
- B.
Convectional
- C.
Cyclonic
- D.
Frontal
Correct Answer
B. ConvectionalExplanation
Convectional precipitation refers to the type of precipitation that occurs due to the heating and cooling of air masses, typically during summer storms or showers in tropical and continental climates. As the air near the surface heats up, it becomes less dense and rises, creating an updraft. As the air rises, it cools and condenses, forming clouds and eventually leading to precipitation. This process is commonly observed in areas with high temperatures and abundant moisture, where the heating of the surface causes the air to rise and form convection currents. Therefore, convectional precipitation is the most suitable explanation for the given question.Rate this question:

- A.
Slopes, wind velocities
- B.
Pressure gradients, wind velocities
- C.
Lapse rates, convectional flows
- D.
Slopes, mountain and valley breezes
Correct Answer
B. Pressure gradients, wind velocitiesExplanation
When the distances between high- and low-pressure zones are short, it indicates a significant difference in pressure over a small area. This steep pressure gradient creates strong pressure gradients, which in turn result in high wind velocities. Therefore, the correct answer is "pressure gradients, wind velocities."Rate this question:

Rainfall is caused by
- A.
Increasing air temperature.
- B.
Cooling of saturated air.
- C.
Decreasing relative humidity.
- D.
Location along a rainshadow.
Correct Answer
B. Cooling of saturated air.Explanation
Rainfall is caused by the cooling of saturated air. When warm air rises and cools, it reaches its dew point, causing the water vapor in the air to condense into water droplets. These droplets then form clouds, which can eventually lead to rainfall. Saturation occurs when the air is holding as much moisture as it can at a given temperature. As the air cools, it becomes unable to hold all the moisture, leading to the release of water in the form of precipitation. Therefore, the cooling of saturated air is the correct explanation for the cause of rainfall.Rate this question:

- A.
Primarily at the earth's surface and secondarily in the atmosphere.
- B.
By the way of solar radiation, or insolation.
- C.
Through the collection of solar energy.
- D.
By means of the circumpolar vortex.
Correct Answer
A. Primarily at the earth's surface and secondarily in the atmosphere.Explanation
The correct answer is primarily at the earth's surface and secondarily in the atmosphere because solar radiation from the sun reaches the earth's surface and is absorbed, causing it to heat up. This heat is then transferred to the atmosphere through convection, where it contributes to the overall temperature of the atmosphere.Rate this question:

The windward side of hills and mountains generally receives more precipitation than the leeward side.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The windward side of hills and mountains typically receives more precipitation because as the prevailing winds approach the windward side, they are forced to rise due to the topography. As the air rises, it cools and condenses, leading to the formation of clouds and precipitation. On the other hand, the leeward side is sheltered from the prevailing winds and experiences a rain shadow effect, resulting in drier conditions and less precipitation.Rate this question:

The Coriolis effect means that wind appears to veer toward the
- A.
Right in the Southern Hemisphere and toward the left in the Northern Hemisphere.
- B.
Right in both Southern and Northern Hemispheres.
- C.
Left in the Southern Hemisphere and towards the right in the Northern Hemisphere.
- D.
Left in the Southern Hemisphere and toward the left in the Northern Hemisphere.
Correct Answer
C. Left in the Southern Hemisphere and towards the right in the Northern Hemisphere.Explanation
The Coriolis effect is a phenomenon that is caused by the rotation of the Earth. As the Earth rotates, objects (including air molecules) that are moving across its surface appear to be deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This is due to the fact that the Earth's rotation causes a greater velocity at the equator compared to the poles. Therefore, in the Southern Hemisphere, wind appears to veer to the left, while in the Northern Hemisphere, it appears to veer to the right.Rate this question:

Warm air rises and tends to move away from the
- A.
Equatorial low-pressure belt.
- B.
Subtropical high-pressure belt.
- C.
Northeast trades.
- D.
Westerlies.
Correct Answer
A. Equatorial low-pressure belt.Explanation
The equatorial low-pressure belt is characterized by warm air rising due to the intense heating of the Earth's surface near the equator. As the air rises, it creates a low-pressure area. This rising warm air tends to move away from the equatorial low-pressure belt, creating atmospheric circulation patterns known as trade winds. These trade winds blow from the subtropical high-pressure belt towards the equatorial low-pressure belt, completing the global circulation of air. Therefore, the correct answer is the equatorial low-pressure belt.Rate this question:

Correct Answer
C. Cold ocean currents.Explanation
Coastal deserts of the world usually border cold ocean currents. Cold ocean currents are characterized by low temperatures and carry cold water from higher latitudes towards the equator. As these currents flow along the coast, they cool down the adjacent air, leading to a decrease in humidity and precipitation. This results in arid conditions and the formation of coastal deserts.Rate this question:

Movement of ocean water (currents) is NOT caused by
- A.
Condensation nuclei.
- B.
Differences in water density.
- C.
Wind patterns.
- D.
The pressure gradient force.
Correct Answer
A. Condensation nuclei.Explanation
Ocean currents are the continuous, directed movement of ocean water caused by various factors. Wind patterns play a significant role in the formation and direction of ocean currents. Differences in water density, due to variations in temperature and salinity, also contribute to the movement of ocean water. Additionally, the pressure gradient force, which is the force exerted by differences in atmospheric pressure, influences the direction and speed of ocean currents. However, condensation nuclei, which are tiny particles in the atmosphere that water vapor condenses onto to form clouds, do not directly cause the movement of ocean currents.Rate this question:

The earth's atmosphere is heated primarily by the process of
- A.
Direct solar radiation.
- B.
Reradiation from the earth.
- C.
Absorption from the earth.
- D.
Latent heat of condensation.
Correct Answer
B. Reradiation from the earth.Explanation
The correct answer is reradiation from the earth. This is because when the sun's rays reach the Earth's surface, they heat it up. The Earth then radiates this heat back into the atmosphere in the form of infrared radiation. This process is known as reradiation or terrestrial radiation. The atmosphere absorbs some of this radiation, which helps to heat it up. Without this reradiation, the Earth's atmosphere would not be heated effectively.Rate this question:

What type of precipitation is caused by air being heated at the surface of the earth?
- A.
Convectional
- B.
Conductional
- C.
Orographic
- D.
Cyclonic
Correct Answer
A. ConvectionalExplanation
Convectional precipitation is caused by the heating of air at the surface of the earth. As the air heats up, it becomes less dense and rises, creating an updraft. As the air rises, it cools and condenses, forming clouds and eventually precipitation. This type of precipitation is commonly associated with thunderstorms and is often localized, occurring in specific areas where the air is being heated rapidly.Rate this question:

The intensity and duration of radiation that various places on the earth receive from the sun depend mainly on
- A.
Weather conditions.
- B.
The angle at which the sun's rays strike the earth.
- C.
Earth rotation.
- D.
The earth surface material.
Correct Answer
B. The angle at which the sun's rays strike the earth.Explanation
The intensity and duration of radiation that various places on the earth receive from the sun depend mainly on the angle at which the sun's rays strike the earth. This is because the angle of the sun's rays affects the amount of energy that is received per unit area. When the sun's rays strike the earth at a higher angle, the energy is concentrated over a smaller area, resulting in higher intensity radiation. Conversely, when the sun's rays strike the earth at a lower angle, the energy is spread out over a larger area, resulting in lower intensity radiation. The duration of radiation also depends on the angle, as the sun's rays are more direct and concentrated when the angle is higher, leading to longer periods of exposure.Rate this question:

When it is winter in the Northern Hemisphere, it is summer in the Southern Hemisphere.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
This statement is true because of the tilt of the Earth's axis. During winter in the Northern Hemisphere, the North Pole is tilted away from the sun, causing less direct sunlight and colder temperatures. At the same time, the South Pole is tilted towards the sun, resulting in more direct sunlight and warmer temperatures, which is summer in the Southern Hemisphere. This phenomenon is due to the Earth's axial tilt and its orbit around the sun.Rate this question:
-
- 27.
If the earth was not tilted from the perpendicular, then solar energy received at a given latitude would not vary during the course of the year.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true because the tilt of the Earth's axis is what causes the variation in solar energy received at different latitudes throughout the year. If the Earth was not tilted, the angle at which the sun's rays hit the Earth would be constant, resulting in a consistent amount of solar energy received at any given latitude. However, because of the tilt, the angle changes as the Earth orbits the sun, leading to the seasons and variations in solar energy.Rate this question:

Valley breezes usually occur at night, and mountain breezes usually occur in the day.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Valley breezes and mountain breezes occur at opposite times of the day. Valley breezes are typically observed during the day when the sun heats up the valley floor, causing the air to rise and creating a breeze that moves up the valley slopes. On the other hand, mountain breezes occur at night when the mountain slopes cool down faster than the valley floor, causing the air to descend and creating a breeze that moves down the mountain slopes. Therefore, the statement that valley breezes occur at night and mountain breezes occur in the day is false.Rate this question:

Temperature inversion never affects air pollution.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Temperature inversion can actually worsen air pollution. In a temperature inversion, warm air is trapped above a layer of cool air near the surface. This prevents the vertical mixing of pollutants, leading to their accumulation at ground level. As a result, air pollution levels can increase significantly during temperature inversions. Therefore, the statement that temperature inversion never affects air pollution is incorrect.Rate this question:

A temperature inversion occurs when
- A.
There is a sudden drop in temperature.
- B.
The normal duirnal cycle of cool mornings and warm afternoons is reversed.
- C.
Air at lower altitudes is cooler than air aloft.
- D.
Smog increases to dangerous levels.
Correct Answer
C. Air at lower altitudes is cooler than air aloft.Explanation
A temperature inversion occurs when air at lower altitudes is cooler than air aloft. This is opposite to the normal vertical temperature gradient, where temperature usually decreases with increasing altitude. In a temperature inversion, a layer of cool air becomes trapped beneath a layer of warmer air, preventing vertical mixing of the atmosphere. This can lead to the formation of fog, smog, or other pollutants being trapped near the surface, as well as affecting weather patterns and air quality.Rate this question:

- B.
Higher summer temperatures and higher winter temperatures.
- C.
Lower summer temperatures and lower winter temperatures.
- D.
Higher summer temperatures and lower winter temperatures.
Correct Answer
D. Higher summer temperatures and lower winter temperatures.Explanation
Regions located great distances from the sea tend to have higher summer temperatures because they are not influenced by the cooling effect of the ocean. Without the moderating influence of the sea, these regions experience hotter summers. On the other hand, they have lower winter temperatures because they are not protected by the ocean's warmth. The absence of the ocean's heat retention leads to colder winters in these inland areas.Rate this question:

The type of precipitation that is associated with hills and mountains is called
- A.
Convectional.
- B.
Orographic.
- C.
Frontal.
- D.
Cyclonic.
Correct Answer
B. Orographic.Explanation
Orographic precipitation occurs when moist air is forced to rise over hills or mountains. As the air rises, it cools and condenses, leading to the formation of clouds and precipitation. This type of precipitation is commonly seen on the windward side of mountains, where the air is forced to rise, and results in higher precipitation amounts compared to the leeward side. Convectional precipitation is caused by the heating of the Earth's surface, frontal precipitation occurs when two air masses of different temperatures meet, and cyclonic precipitation is associated with low-pressure systems. However, in this context, the correct answer is orographic precipitation because it specifically refers to precipitation associated with hills and mountains.Rate this question:

Reradiates its energy faster than does water.
- B.
Reradiates its energy slower than does water.
- C.
Reflects its energy faster than does water.
- D.
Reflects it energy slower than does water.
Correct Answer
A. Reradiates its energy faster than does water.Explanation
When land is warmer than water, it reradiates its energy faster than water because land has a lower specific heat capacity compared to water. This means that land can absorb and release heat more quickly than water. As a result, the land loses heat more rapidly through radiation, while water retains heat for a longer period of time.Rate this question:

When neither the Northern nor the Southern Hemisphere is tilted toward the sun, the sun's vertical rays are felt at
- A.
23.5° north and south latitude.
- B.
The equator.
- C.
67.5° north and south latitude.
- D.
The summer solstice.
Correct Answer
B. The equator.Explanation
When neither the Northern nor the Southern Hemisphere is tilted toward the sun, it means that the Earth is in a position where its axis is not inclined with respect to the sun's rays. In this position, the sun's vertical rays are felt at the equator. The equator is the line of latitude that is equidistant from the North and South Poles, and it experiences the most direct sunlight when the Earth is not tilted. This is because the equator is situated in the middle of the Earth's surface, making it the closest point to the sun's rays when the axis is not tilted.Rate this question:
