Question

which factor most directly influences the formation of prevailing winds on earth? (1 point)
ocean current directions
uneven heating of earths surface by the sun
earths rotation speed
mountain range locations

Explanation:

To determine the factor most directly influencing prevailing winds, we analyze each option:

• Ocean current directions: Ocean currents are influenced by winds, not the primary cause of prevailing winds.
• Uneven heating of Earth's surface by the sun: This creates temperature differences, leading to pressure gradients. Air moves from high to low pressure, driving wind formation. This is the fundamental cause.
• Earth's rotation speed: Affects wind direction (Coriolis effect) but not the initial formation of wind systems.
• Mountain range locations: Influence local wind patterns (e.g., orographic lift) but are not the primary driver of prevailing winds.

Answer:

B. Uneven heating of Earth's surface by the sun
