Answers
1
What is the pattern of air and heat movement in the Hadley Cells?
air moves from north to south
air moves from east to west
cool air rises, warm air sinks
warm air rises, cooler air sinks
2
Wind is caused by a change in pressure systems. What causes high and low pressure?
air temperature
solar radiation
changes in humidity
air pressure
3
The pictures above show valley and mountain breezes. What are the three processes that explain why these breezes form?
Convection Currents
Amount of Direct Heat
Upwelling
Coriolis Effect
Low & High Pressure Systems
4
Movement of air from high pressure to low pressure.
Rotation
Low Pressure
Absorption
Wind
Convection
5
How does the atmosphere balance the unequal heating of Earth's surface?
warm air toward high latitudes and cool air toward the equator.
cool air toward the east and warm air toward the west.
warm air toward the east and cool air toward the west.
cool air toward high latitudes and warm air toward the equator.
6
Warmer air rises while cold air sinks creating air movement.
Convection
Rotation
Absorption
Wind
Low Pressure
7
Why does the air move toward the land during the day and away from the land at night?
The greenhouse effect causes climates to change.
The Coriolis effect causes the winds to change direction.
Air moves from low pressure to high pressure.
Air moves from high pressure to low pressure.
8
Sunlight that hits the Earth at close to 90°
Indirect Sunlight
Seasons
Climate Zones
Direct Sunlight
Wind
9
What process does this diagram represent?
currents
Coriolis effect
convection
greenhouse effect
10
Tropical, Temperate and Polar are examples of:
Climate Zones
Wind
Indirect Sunlight
Direct Sunlight
Seasons
11
Energy from the sun strikes a surface and is converted to heat.
Absorption
Rotation
Low Pressure
Convection
Wind
12
Warm air rises.
Low Pressure
Wind
Rotation
Absorption
Convection
13
What causes the pressure differences on Earth?
when water vapor in the air rises then falls.
by accumulations of clouds in different areas.
by a sudden drop in humidity.
by the unequal heating of Earth’s surface.
14
Caused by the tilt of Earth as it revolves around the Sun.
Seasons
Direct Sunlight
Indirect Sunlight
Wind
Climate Zones
15
What direction do global winds flow across most of the US?
South to West
West to East
North to South
East to West
16
How does the Coriolis effect alter the flow of winds in the atmosphere?
They travel across the ocean because the wind blows them.
They move up when the air is warm and down when the air is cold.
They curve instead of travelling in a straight line.
They are constsantyly changing course.
