Question

question 7 of 10
what causes two distinct pressure zones between the equator and the poles?
a. the fact that nitrogen is heavier than oxygen
b. earths rotation
c. the troposphere interacting with the mesosphere
d. the ozone layer

Explanation:

Earth's rotation causes the Coriolis effect. This effect influences the movement of air masses, leading to the formation of distinct pressure zones between the equator and the poles. The Coriolis effect deflects moving air, creating patterns that result in these pressure differences. Option A about nitrogen and oxygen density is not relevant to pressure zone formation between equator and poles. The troposphere and mesosphere (Option C) are different atmospheric layers with little direct interaction in this context. The ozone layer (Option D) primarily absorbs UV radiation and is not the cause of these pressure zones.

Answer:

B. Earth's rotation
