Global Atmospheric Circulation Flashcards
Complete the whole deck every geography lesson on the day.
Where does the Earth receive all of its heat energy from?
The sun.
Why is the equator the hottest part of the earth?
As it is the main concentration point of the sun so all of the concentrated heat (thermal) energy is transferred to the most.
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 an area of l_______ p________.
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.
A humid / Mediterranean tropical climate. it is very hot and quite dry and wet at the same time.
Complete the following sentence:
As air in the atmosphere starts to cool, it is s_______ and becomes more d_______- this creates and area of h______ p______.
As air in the atmosphere starts to cool, it is sinks and becomes more dense- this creates and area of high pressure.
What climatic conditions would you associate with high pressure systems?
Light winds and settled precipitation.
What are the 3 global circulation cells called?
Hadley cell, Ferrel Cell and the Polar cell.
What is responsible for redistributing heat energy around the world?
Circulation of the atmosphere and oceans.
True or False? Air moves from areas of high pressure to an area of low pressure.
True.
True or False? Ocean current transfer heat energy from areas of surplus (extra heat) to areas of deficit (not enough head).
True.
On a climate graph, what do blue bars represent?
Precipitation.
On a climate graph, what does the red line represent?
Temperature.
