What happens to this water vapor?
The water vapor evaporates and escapes into space. New water is formed by precipitation.
The water vapor only rises for a very short time, then settles back into the ocean unnoticed.
The water vapor pushes clouds out of the way as it rises. This causes overcast conditions to clear.
The water vapor condenses as it cools, then it forms clouds. It returns to the Earth as precipitation.
Convection currents, resulting from uneven heating of the Earth's surface, cause (a) to form.
wind
fossils
mountains
volcanoes
When it is raining, water is returning to Earth during a water cycle stage called a.
condensation
deposition
precipitation
evaporation
Where does the initial source of energy come from that creates winds and thus surface currents?
the moon’s gravity
the sun
the rotation of the Earth
wind
In the figure to the right, which of the following is the correct symbol for a stationary front?
1
2
3
Compared to the air at the poles, the air at the equator is warmer and
less dense, creating an area of high pressure as it rises
less dense, creating an area of low pressure as it rises
denser, creating an area of low pressure as it rises
denser, creating an area of high pressure as it rises
Solar energy heats the surface of the Earth, including the ground, rocks, and even roadways. As the temperature of these surfaces increases, heat energy is released back into the atmosphere, forming a pocket of warm air. As the warm air pocket rises, it is replaced by cooler air. This process is responsible for many of the weather patterns in our atmosphere, and is known as
convection
conduction
transpiration
evaporation
If a cool surface current flows along a coastline, what effect might it have on the climate in that area?
It will bring warmer temperatures in the summer and milder temperatures in the winters.
It will bring drier air and cause many droughts.
It will have no long term effect on climate in that area.
It will bring cooler temperatures in the summer and colder temperatures in the winters.
How can you tell which direction a front is moving on a weather map?
Look at the color of the front
Look for H’s or L’s
Look which way the triangles or circles are pointing
Look for rain clouds
