Geography Test 17/04 Flashcards
What are the 4 layers of the earth?(test)
crust, mantle, outer core, inner core
Where does the earth receive all of its heat energy from
the sun
why is the equator the hottest part of the earth
It is closest to the sun/ the sun’s energy is most concentrated here
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__ 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 at the equator
High temperatures and heavy rainfall (warm and wet)
Complete the following sentence
As air in the atmosphere starts to cool, it s_____ and becomes more d______ - this creates an area 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?
Dry/arid conditions – little to no rainfall because there is no opportunity for clouds
to form
What are the x3 global circulation cells called?
Polar, Ferrel and Hadley
What is responsible for redistributing heat energy around the world?
Winds and ocean currents
True or False? Air moves from areas of high pressure to areas of low pressure.
True – the sustained movement of air creates wind systems across the Earth
True or False? Ocean currents transfer heat energy from areas of surplus (extra heat) to areas of deficit (not enough heat).
True – they redistribute heat energy to areas that need it
On a climate graph, what do the blue bars represent?
Precipitation (rainfall)
On a climate graph, what does the red line represent?
Temperature
