Global circulation patterns of winds and ocean currents, which drive weather systems and, ultimately, climate patterns are created by
A) the coriolis force.
B) frictional force caused by the Earth's spinning on its axis.
C) imbalances created by energy surpluses and deficits at the equator and poles, respectively.
D) the differential heating properties of land and water.

Question

Quizplus · Accepted Answer

The imbalances created by energy surpluses and deficits at the equator and poles, respectively, are the primary drivers of global circulation patterns of winds and ocean currents. At the equator, incoming solar radiation is at its most intense, leading to a surplus of energy that drives warm, moist air upwards into the atmosphere. This causes a low-pressure system at the equator, which draws in air from surrounding regions. As the warm, moist air rises, it cools and forms clouds, leading to precipitation. At the poles, there is a deficit of energy due to lower solar radiation, which causes air to sink and create high-pressure systems. This creates a circulation pattern that drives winds and ocean currents around the planet. The Coriolis force and differential heating properties of land and water also play a role in shaping global circulation patterns but are secondary factors compared to the energy imbalances at the equator and poles.
