The image below shows a certain type of global wind:
equator
17
what best describes these winds?
a-polar easterlies that curve due to air above poles being relatively cooler
b-jet streams that curve due to air above equator being relatively warmer
c-trade winds blowing in a curved manner due to the rotation of earth
d-polar westerlies blowing in a curved manner due to coriolis effect
