"Globally, varying air pressures result from large-scale air circulation driven by heating and cooling." Evaluate this statement.
A) It is true; air pressure increases as hot air rises and pushes against cooler air masses.
B) It is partially true; however, Earth's rotation also plays an important part.
C) It is partially true; however, it is much more complicated due to ocean currents.
D) It is false; varying air pressure is caused solely by Earth's rotation and ocean currents.

Question

Quizplus · Accepted Answer

The statement is partially true because while heating and cooling do drive large-scale air circulation and thus affect air pressures, Earth's rotation (the Coriolis effect) also significantly influences air movement and pressure distribution. Ocean currents do affect climate and weather patterns, but the statement specifically about air pressures is more directly influenced by air circulation and Earth's rotation.
