Global Atmospheric Circulation Flashcards
Where does the Earth receive all of its heat energy from?
The sun.
Why is the equator the hottest part of the Earth.
The sun’s rays are more concentrated on it.
Complete the following sentence.
As the ground heats up, it warms the air above it. Warm air r_____ because it is less d_____- this creates and area of l_____ pressure.
As the ground heats up , it warms the air above it. Warm air rises because it is less dense- this creates an area of low pressure.
Describe the climate of the equator.
The equator’s climate is hot, humid and wet.
Complete the following sentence.
As the air in the atmosphere starts to cool, it s_____ and becomes more d_____- this creates an are of h_____ pressure.
As air in the atmosphere starts to cool, it sinks and becomes more dense- this creates an area of high pressure.
What climatic conditions would you associate with high pressure systems?
There is little rainfall as the cool air is at ground level.
What are the 3 global circulation cells?
The Hadley cell
The Ferrel cell
The Polar cell
What is responsible for redisributing heat energy around the world?
The Ocean
True or False? Air moves from areas of high pressure to areas of low pressure.
True
True or False? Ocean current transfer heat energy from areas of surplus to areas of deficit.
True
On a climate graph what do the blue bars represent?

On a climate graph what does the red line represent?
Temperature
