Question

quiz global patterns of atmospheric movement
which statement most accurately describes wind?
a. wind is the cyclical movement of air from warm areas to cold areas.
b. wind is the cyclical rising and sinking of air due to convection.
c. wind is the movement of air from a high - pressure area to a low - pressure area.
d. wind is the movement of air from a low - pressure area to a high - pressure area.

Explanation:

To determine the correct description of wind, we analyze each option:

• Option A: Wind isn't strictly cyclical movement from warm to cold areas; it's driven by pressure differences, not just temperature zones.
• Option B: The rising and sinking of air (convection) is part of atmospheric circulation, but wind is horizontal air movement, not just vertical rising/sinking.
• Option C: Wind is caused by pressure gradients. Air moves from high - pressure (H) areas to low - pressure (L) areas to balance pressure, which matches the diagram (arrow from H to L) and the definition of wind.
• Option D: Air moves from high to low pressure, not low to high, so this is incorrect.

Answer:

C. Wind is the movement of air from a high - pressure area to a low - pressure area.
