What is air that moves horizontally, or parallel to the ground...
- A.
Wind
- B.
Air pressure
- C.
Weather
Correct Answer
A. WindExplanation
The correct answer is wind. Wind refers to the horizontal movement of air parallel to the ground. It is caused by the uneven heating of the Earth's surface, which creates differences in air pressure. These pressure differences then cause air to move from areas of high pressure to areas of low pressure, resulting in wind. Weather and air pressure are related to wind, but they are not the specific terms used to describe the horizontal movement of air.Rate this question:

All winds in the upper hemispheres
- B.
Winds located at the horse latitudes
- C.
Winds that travel thousands of km in steady patterns.
Correct Answer
C. Winds that travel thousands of km in steady patterns.Explanation
Global winds are large-scale winds that circulate around the Earth in steady patterns. These winds cover long distances, often spanning thousands of kilometers, and are influenced by factors such as the rotation of the Earth, the unequal heating of its surface, and the Coriolis effect. They play a crucial role in shaping weather patterns and climate across the globe.Rate this question:
-
- 5.
What effect is in play when winds curve?
- A.
Global warming effect
- B.
Coriolis effect
- C.
Saturation
Correct Answer
B. Coriolis effectExplanation
The Coriolis effect is the explanation for the curving of winds. It is caused by the rotation of the Earth. As the Earth rotates, objects moving over its surface, like air, appear to curve from their straight path. In the Northern Hemisphere, winds are deflected to the right, while in the Southern Hemisphere, they are deflected to the left. This effect is responsible for the rotation of weather systems, such as cyclones and anticyclones, and plays a crucial role in shaping global wind patterns.Rate this question:

What way do the jet streams flow?
- A.
North
- B.
South
- C.
West
- D.
East
Correct Answer
D. EastExplanation
Jet streams are fast flowing, narrow air currents found in the upper atmosphere. They generally flow from west to east, driven by the temperature and pressure differences between polar and tropical air masses. This eastward flow is a result of the Earth's rotation, known as the Coriolis effect. The jet streams play a crucial role in weather patterns and are important for aviation, as they can either assist or hinder the speed and direction of aircraft.Rate this question:

What are the winds that change direction with season?
- A.
Land breezes
- B.
Sea breezes
- C.
Monsoons
Correct Answer
C. MonsoonsExplanation
Monsoons are winds that change direction with the season. They are characterized by a shift in wind direction, typically occurring between summer and winter. During summer, monsoon winds blow from the ocean towards the land, bringing heavy rainfall. In winter, the wind direction reverses, blowing from the land towards the ocean. This seasonal change in wind direction is caused by the differential heating of land and water, resulting in the formation of monsoons.Rate this question:

What is the process in which liquid changes to a gas?
- A.
Evaporation
- B.
Condensation
- C.
Precipitation
Correct Answer
A. EvaporationExplanation
Evaporation is the process in which a liquid changes to a gas. This occurs when the molecules of the liquid gain enough energy to break free from the attractive forces holding them together and escape into the surrounding environment as gas molecules. Evaporation commonly takes place at the surface of a liquid, and it is influenced by factors such as temperature, surface area, and the presence of air currents.Rate this question:
-
- 9.
What is condensation?
- A.
Gas to liquid
- B.
Liquid to gas
Correct Answer
A. Gas to liquidExplanation
Condensation is the process in which a gas changes into a liquid state. This occurs when the temperature of the gas decreases, causing the gas particles to lose energy and come closer together. As a result, the gas molecules slow down and form bonds with each other, forming liquid droplets. This phase change is commonly observed when water vapor in the air cools down and turns into liquid water droplets, such as when dew forms on grass or when steam from a hot shower turns into water droplets on a mirror.Rate this question:

What is any type of liquid that falls to Earth's surface?
- A.
Particulates
- B.
Precipitation
- C.
Water droplets
Correct Answer
B. PrecipitationExplanation
Precipitation refers to any type of liquid that falls to Earth's surface. This can include rain, snow, sleet, or hail. It is the result of water vapor condensing in the atmosphere and then falling back down to the ground. Particulates are small particles suspended in the air, and water droplets are small droplets of liquid water. However, precipitation encompasses all forms of liquid that reach the Earth's surface.Rate this question:

What is the amount of water vapor in air?
- A.
Humidity
- B.
Relative humidity
- C.
Precipitation
Correct Answer
A. HumidityExplanation
Humidity refers to the amount of water vapor present in the air. It is a measure of the moisture content in the atmosphere. Relative humidity, on the other hand, is the ratio of the actual amount of water vapor present in the air to the maximum amount of water vapor that the air can hold at a particular temperature. Precipitation, on the other hand, refers to any form of water that falls from the atmosphere to the Earth's surface, such as rain, snow, sleet, or hail. Therefore, the correct answer is humidity as it directly relates to the amount of water vapor in the air.Rate this question:
-
- 12.
What is it when the rates of evaporation and condensation are equal?
- A.
Humidity
- B.
Saturation
- C.
Water vapor
Correct Answer
B. SaturationExplanation
When the rates of evaporation and condensation are equal, it indicates that the air is holding as much water vapor as it can at a given temperature. This state is known as saturation. Saturation occurs when the air is fully saturated with water vapor, and any additional increase in humidity would result in the formation of clouds or precipitation.Rate this question:
-
- 13.
What does relative humidity compare?
- A.
The amount of water vapor to the max. of water vapor possible for that temp.
- B.
Amount of water vapor to saturation
- C.
Amount of humidity multiplied by saturation
Correct Answer
A. The amount of water vapor to the max. of water vapor possible for that temp.Explanation
Relative humidity compares the amount of water vapor in the air to the maximum amount of water vapor that can exist at a particular temperature. It is expressed as a percentage and indicates how close the air is to being saturated with water vapor.Rate this question:

What type of cloud is most likely to bring a thunderstorm?
- A.
Cumulus
- B.
Cumulonimbus
- C.
Cirrus
Correct Answer
A. CumulusExplanation
Cumulus clouds are puffy, white clouds that are often associated with fair weather. However, when cumulus clouds become larger and develop vertically, they can turn into cumulonimbus clouds. Cumulonimbus clouds are known as thunderstorm clouds because they are capable of producing heavy rain, lightning, thunder, and even hail. Therefore, cumulonimbus clouds are most likely to bring a thunderstorm.Rate this question:
-
- 15.
What are clouds made of?
- A.
Water vapor
- B.
Water droplets
Correct Answer
B. Water dropletsExplanation
Clouds are made up of water droplets. When warm air rises and cools, it cannot hold as much moisture, causing the water vapor in the air to condense into tiny water droplets. These droplets then gather together to form clouds. The size and shape of the water droplets in the cloud determine the type of cloud and its appearance.Rate this question:
-

Clouds made of ice crystals form under ______________________?
- A.
High pressure
- B.
High altitude
- C.
Low pressure
Correct Answer
B. High altitudeExplanation
Clouds made of ice crystals form under high altitude because at high altitudes, the air is colder and the water vapor in the air condenses into ice crystals. As the air rises to higher altitudes, it cools down and reaches its dew point, causing the water vapor to change into solid ice crystals. This process leads to the formation of high-altitude clouds, such as cirrus clouds, which are composed of ice crystals rather than water droplets.Rate this question:

- 17.
As _____________ increases, density decreases.
- A.
Altitude
- B.
Air pressure
- C.
Density
Correct Answer
A. AltitudeExplanation
As altitude increases, density decreases. This is because as altitude increases, the air pressure decreases. With lower air pressure, there are fewer air molecules per unit volume, resulting in a decrease in density.Rate this question:

- A.
Horse latitudes and westerlies
- B.
Easterlies and westerlies
- C.
Horse latitudes and doldrums
Correct Answer
C. Horse latitudes and doldrumsExplanation
The calm regions referred to in the question are known as horse latitudes and doldrums. Horse latitudes are located at around 30 degrees north and south of the equator, where there is little to no wind. The doldrums, also known as the Intertropical Convergence Zone, are located near the equator and are characterized by light and variable winds. Therefore, the correct answer is horse latitudes and doldrums.Rate this question:

What wind belt flows from the horse latitudes toward the equator?
- A.
Westerlies
- B.
Trade winds
- C.
Doldrums
Correct Answer
B. Trade windsExplanation
The trade winds flow from the horse latitudes towards the equator. These winds are characterized by their consistent direction and strength, blowing from the east to the west in both the Northern and Southern Hemispheres. They are caused by the rotation of the Earth and the temperature differences between the equator and the poles. The trade winds are important for sailing and navigation, as they were historically used by traders to sail across the oceans.Rate this question:

What local wind occurs when cool air pushes into the ocean?
- A.
Land Breeze
- B.
Sea breeze
Correct Answer
A. Land BreezeExplanation
A land breeze occurs when cool air from the land pushes into the ocean. During the night, the land cools down faster than the water, creating a temperature difference. This temperature difference causes the cool air to flow from the land towards the warmer ocean. As a result, the land breeze brings cooler air and lower humidity to the coastal areas.Rate this question:

What clouds are puffy like cotton balls?
- A.
Cumulus
- B.
Cirrus
- C.
Stratus
Correct Answer
A. CumulusExplanation
Cumulus clouds are puffy like cotton balls because they have a rounded shape and a white, fluffy appearance. These clouds form when warm air rises and cools, causing water vapor to condense into visible droplets. The droplets in cumulus clouds are often small and widely spaced, giving them their distinct puffy appearance. Cumulus clouds are commonly seen on fair weather days and are often associated with pleasant and calm conditions.Rate this question:

What forms when water droplets or ice crystals melt as they fall?
- A.
Rain or drizzle
- B.
Sleet
- C.
Snow
Correct Answer
A. Rain or drizzleExplanation
When water droplets or ice crystals melt as they fall, they form rain or drizzle. This occurs when the temperature of the air is above freezing, causing the frozen water particles to melt into liquid form. Rain refers to larger water droplets that fall from the clouds, while drizzle refers to smaller droplets that fall slowly and lightly. Both rain and drizzle are forms of precipitation that result from the melting of water droplets or ice crystals.Rate this question:
-
- 23.
What forms from ice crystals that merge in clouds?
- A.
Sleet
- B.
Snow
- C.
Hail
Correct Answer
B. SnowExplanation
Snow forms from ice crystals that merge together in clouds. When the temperature in the clouds is below freezing, the water vapor in the air condenses onto ice nuclei, forming ice crystals. These ice crystals then collide and stick together, forming snowflakes. As more ice crystals merge, the snowflakes become larger and eventually fall to the ground as snow.Rate this question:
-
- 24.
____________ forms when ice pellets move up and down in clouds, growing larger as they gain layers of ice.
- A.
Snow
- B.
Hail
- C.
Rain
Correct Answer
B. HailExplanation
Hail forms when ice pellets move up and down in clouds, growing larger as they gain layers of ice. This process occurs when there are strong updrafts in a thunderstorm cloud, which carry the ice pellets upward into the colder regions of the cloud where they can accumulate more ice. As the pellets are lifted and fall back down repeatedly, they continue to grow in size before eventually becoming too heavy for the updrafts to support, causing them to fall to the ground as hail.Rate this question:
-
- 25.
What freezes into ice pellets while falling through cold air?
- A.
Hail
- B.
Sleet
- C.
Freezing rain
Correct Answer
B. SleetExplanation
Sleet is the correct answer because it refers to frozen raindrops that freeze into ice pellets as they fall through cold air. Hail is incorrect because it is formed by layers of ice building up on a frozen raindrop, while freezing rain is incorrect because it refers to rain that freezes upon contact with a cold surface, not while falling through the air.Rate this question:
-
- 26.
______________ is rain that freezes when it hits the ground or other surfaces.
- A.
Freezing rain
- B.
Snow
- C.
Hail
Correct Answer
A. Freezing rainExplanation
Freezing rain is the correct answer because it refers to raindrops that become supercooled as they fall through a layer of subfreezing air near the ground. This causes the raindrops to freeze upon contact with the ground or other surfaces, forming a layer of ice. Unlike snow, which falls as ice crystals, freezing rain starts as liquid water and freezes upon impact. Hail, on the other hand, is formed in thunderstorms and consists of solid ice pellets that are larger than freezing raindrops.Rate this question:
