Air currents are caused by differences in temperature, which are created by
a
energy from the Sun heating Earth.
b
energy from the Moon heating Earth.
c
energy from volcanic eruptions on Earth's surface.
d
energy from geological processes within Earth's core.
a) energy from the Sun heating Earth.
The diagrams show typical daily wind patterns along the shoreline.
Why does the wind reverse direction when it changes from day to night, and again when it changes from night to day?
a
Air in the upper atmosphere heats faster than air in the lower atmosphere. As the warm air sinks during the day, it draws cool air from over the water to replace it in the upper atmosphere. When the Sun goes down, the cool air in the lower atmosphere rises, causing the process to reverse.
b
Air in the lower atmosphere heats faster than air in the upper atmosphere. As the cool air sinks during the day, it draws warm air from over the water to replace it in the upper atmosphere. When the Sun goes down, the warm air in the lower atmosphere rises, causing the process to reverse.
c
Land heats faster than water, causing air over land to warm and rise faster than air over water. This lowers air pressure over land and draws in cooler air from over the water during the day. Because water retains heat longer than land, this process reverses at night.
d
Water heats faster than land, causing air over water to warm and rise faster than air over land. This lowers air pressure over water and draws in cooler air from over the land during the day. Because land retains heat longer than water, this process reverses at night.
c) Land heats faster than water, causing air over land to warm and rise faster than air over water. This lowers air pressure over land and draws in cooler air from over the water during the day. Because water retains heat longer than land, this process reverses at night.
Currents are responsible for transferring the Sun's energy between the equator and the poles
True
False
True.
um mr bot is it false or true
It is True. Currents are responsible for transferring the Sun's energy between the equator and the poles.
Unequal heating of the Earth's surface is the major cause of winds.
True
False
True. The unequal heating of the Earth's surface, due to differences in solar radiation received at different latitudes, is the major cause of winds.
Look at the diagrams.
Based on your knowledge of the Sun's effect on land and water temperature, what does each diagram show?
a
Diagram 1 shows a sea breeze during the day and Diagram 2 shows a land breeze during the night.
b
Diagram 1 shows a sea breeze during the night and Diagram 2 shows a land breeze during the day.
c
Diagram 1 shows a land breeze during the night and Diagram 2 shows a sea breeze during the day.
d
Diagram 1 shows a land breeze during the day and Diagram 2 shows a sea breeze during the night.
