Read the first page of the chapter. Wind moves pollution, chemicals, dust between continents - remember that what we do affects other countries just like what they do affects us. It is hard to believe that the eruption of Mount Pinatubo cooled the earth for 3 years! Tons of industrial pollution and dust from what rapidly industrializing country is degrading the air quality in Washington and Oregon?
- A.
China
- B.
Russia
- C.
India
- D.
Iran
Correct Answer
A. ChinaExplanation
The passage mentions that pollution and dust from a rapidly industrializing country are degrading the air quality in Washington and Oregon. Based on this information, the correct answer is China, as it is known for its rapid industrialization and high levels of pollution.Rate this question:

The boundary between tow air masses with different temperatures and densities is called a _____________
- A.
Climate
- B.
Weather
- C.
Front
- D.
Typhoon
Correct Answer
C. FrontExplanation
A front is the boundary between two air masses with different temperatures and densities. It is where warm air and cold air meet, leading to changes in weather conditions.Rate this question:

After this chapter you should be able to understand what is going on when watching the weather man on tv. Which of the following is often associated with Fair or good weather?
- A.
Low Pressure System
- B.
High Pressure System
- C.
1 atm
- D.
Typhoon
Correct Answer
B. High Pressure SystemExplanation
High pressure systems are often associated with fair or good weather. In a high pressure system, the air is sinking and spreading outwards, creating stable atmospheric conditions. This leads to clear skies, little to no precipitation, and generally calm weather. On the other hand, low pressure systems are associated with unstable atmospheric conditions, which often result in cloudy skies, precipitation, and potentially stormy weather. Therefore, the correct answer is High Pressure System.Rate this question:

The rotation of the earth prevents air currents from moving due north or south from the equator. Wind is deflected to the right in the northern hemisphere and to the left in the southern hemisphere in what is called the ___________ effect.
Correct Answer
Coriolis
coriolis
coroilis
CoroilisExplanation
The rotation of the Earth causes a phenomenon known as the Coriolis effect. This effect causes air currents to be deflected to the right in the northern hemisphere and to the left in the southern hemisphere. It is this deflection that prevents air currents from moving directly north or south from the equator.Rate this question:

Open another web page and google Hadley Cells. Where are the hadley cells located?
- A.
0 - 30 degrees latitude
- B.
30 - 60 degrees latitude
- C.
60 - 90 degrees latitude
Correct Answer
A. 0 - 30 degrees latitudeExplanation
Hadley cells are located between 0 - 30 degrees latitude. These cells are large-scale atmospheric circulation patterns that occur in the tropics. They are characterized by rising air near the equator, which creates low-pressure zones, and sinking air in the subtropics, which creates high-pressure zones. This circulation pattern plays a significant role in shaping global weather patterns and distributing heat around the Earth.Rate this question:

Which is worse for the United States - El Nino or La Nina?
- A.
El Nino
- B.
La Nina
Correct Answer
B. La NinaExplanation
La Nina is worse for the United States because it typically brings colder and wetter conditions, leading to more extreme weather events such as heavy rainfall, flooding, and colder temperatures. This can have significant impacts on agriculture, water resources, and infrastructure, causing economic losses and disruption to daily life. In contrast, El Nino usually brings warmer and drier conditions, which can also have negative effects but may be less severe compared to the impacts of La Nina.Rate this question:

Without the greenhouse gases the average temperature of the planet would be ____ instead of its current 15C (59F)
- A.
- 10C
- B.
-22 C
- C.
5 C
- D.
- 18 C
Correct Answer
D. - 18 CExplanation
Without greenhouse gases, the average temperature of the planet would be significantly colder than its current 15C (59F). The correct answer of -18C suggests that the absence of greenhouse gases would result in a drop of 33 degrees Celsius in the average temperature. This demonstrates the crucial role that greenhouse gases play in trapping heat and maintaining a habitable temperature on Earth.Rate this question:

When moist air blowing inland from an ocean reaches a mountain range, it cools as it is forced to rise and expand. This causes the air to lose most of its moisture as rain and snow on the windward (wind-facing) slopes. As the drier air mass flows down the leeard (awa from the wind) slopes, it draws moisture out of the plants and soil over which it passes. The lower precipitation and the resulting semiarid or arid conditions on the leeward side of high mountains are called the ___________ ______ _________. 3 word answer - spell correctly and all lower case
Correct Answer
rain shadow effect
Rain Shadow Effect
Rain shadow effectExplanation
When moist air is forced to rise and cool as it reaches a mountain range, it releases most of its moisture as rain and snow on the windward slopes. The drier air mass that descends on the leeward side of the mountains then absorbs moisture from the plants and soil, resulting in lower precipitation and semiarid or arid conditions. This phenomenon is known as the rain shadow effect.Rate this question:

Cities also create distinct microclimates. Bricks, concrete, asphalt, and other building materials absorb and hold heat, and buildings block wind flow. Motor vehicles and climate control systems of buildings release large quantities of heat and pollutants. As a result, cities tend to have more haze and smog, higher temperatures, and lower wind speeds than the surrounding country-side. This is known as the _________________________
- A.
City climate effect
- B.
City effect
- C.
Heat island effect
- D.
Human heat effect
Correct Answer
C. Heat island effectExplanation
Cities also create distinct microclimates due to the absorption and retention of heat by building materials, the blocking of wind flow by buildings, and the release of heat and pollutants by motor vehicles and climate control systems. These factors result in cities having more haze and smog, higher temperatures, and lower wind speeds compared to the surrounding countryside. This phenomenon is known as the heat island effect.Rate this question:
