1.1 - Hazardous Earth Flashcards
Cool Air
-Falls; high pressure.
-No clouds.
When the cool, dry air falls at 30°C of latitude north and south, it creates high pressure. High pressure conditions have clear creates skies with little precipitation. These are often arid.
Warm Air
-Rises at the equator.
-Low pressure.
-Condensation.
When warm air rises it creates low pressure. Rising air becoming cooler and under low pressure cannot hold as much moisture and that’s why precipation is high at the equator.
Where on earth gets the most solar radiation (heat/energy rom the sun)?
The equator.
What’s latitude?
The distance away from the equator.
What’s the latitude of the equator?
0°.
What’s low pressure?
Rising air which then cools; condense, forms clouds ad leads to rain.
What’s high pressure?
Sinking air, evapouring moisture and leave cloudless skies and no rain.
Where on earth gets the least solar radiation?
The poles.
What happens to the air when it is heated?
It rises cool, condense and form clouds low pressure.
Where’s the ecosystem highest pressure
Desert & Polar deserts.
where is the heat transferred from and to?
From the equator to the pole.
What does the ocean currents influence?
The climate.
The other name for ocean conveyor belt?
Thermohaline circulation.
How long is the Gulf Stream?
10,000KM
Why is the Gulf Stream called a heat pump?
Because we would need 1,000 nuclear usines.
Ocean Currents.
Line the atmospheric circulation, ocean currents help to redistribute heat energy across the earth.
Covers 67% of the Earth’s surface, therefore oceans receive 67% of the sun’s energy that reaches the Earth.
ITCZ (Inter-Tropical Convergence Zone}
Areas with regular low pressure experience high rainfall totals.
The ITCZ occurs near the equator between 2 Hadley Cells.
Coriolis Effect
Air moves from high to low pressure. However, because the Earth rotates, the air does not follow in a straight line. Winds actually flow a curve path.
Where the Gulf Stream begins?
The Gulf of the Mexico.
