What causes two distinct pressure zones between the equator and the poles?
a. the troposphere interacts with the stratosphere
b. gravity
c. the coriolis effect
d. ionospheric interactions with radiation
(i think i know what the answer is but i just wanted to check, ! )

Option (C)

Explanation:

The Coriolis force is defined as the force that generates due to the rotation of the earth around its imaginary axis. Due to the effect of the Coriolis force, the wind gets deviated. The wind is deviated towards the right in the northern hemisphere, whereas the wind gets deviated towards the left in the southern hemisphere.

Due to this changing wind direction, there occurs the low pressure and the high-pressure zone between the polar and the equatorial zone.  The low pressure zones are formed at the equator and in temperate regions. Whereas, the high-pressure zones are formed at the tropics and the polar region.

Hence, the correct answer is option (C).
