Surface Currents Flashcards
understand how so rad with gran creates surface currents
So Rad With Gran means…
Solar Radiation, Wind, Gravity
The wind starts where?
At the Equator.
Solar radiation is more _ at the Equator and _ intense at the Poles.
intense, less
The radiation intensity is due to what?
Energy spread over a bigger or smaller surface.
High latitudes are at the _.
Poles (Polar bear says “Hi.”)
Low latitudes are at the _.
Equator
Why do air and water particles rise?
They heat up, expand, and become less dense than the air or water around them.
Why do air and water particles sink?
They cool down, condense, and become denser than the air or water around them.
When the wind blows across the surface of the ocean it creates friction and _ the water, making _.
drags, waves
The wind pulls on the surface water. These are called _.
Surface currents
The Coriolis Effect is what?
An apparent force explaining why winds and surface currents curve.
In the Northern Hemisphere, the gyre flows _.
Clockwise
In the Southern Hemisphere, the gyre flows _.
Counterclockwise
A gyre is what and how many are there?
A circular ocean current. There are five major gyres.
Coriolis: An object (particles) appears to be moving in a curved direction to you because your _ is rotating.
