Question

why does a cool breeze blow over the seashore from the ocean on a sunny day?

b. because of the rotation of earth

c. because a conduction current occurs

d. because the land is heating up faster than the ocean

Explanation:

To determine why a cool breeze blows from the ocean to the seashore on a sunny day, we analyze each option:

• Option B: Earth's rotation causes phenomena like Coriolis effect (affecting large - scale winds, not sea - breeze), so B is wrong.
• Option C: Conduction is heat transfer through direct contact. Sea - breeze is due to convection (heat - driven air movement), so C is wrong.
• Option D: Land has lower specific heat capacity than water. On a sunny day, land heats up faster. Warm air over land rises, creating low pressure. Cooler air over the ocean (high pressure) moves towards the seashore, forming the sea - breeze. This matches the sea - breeze mechanism.

Answer:

D. because the land is heating up faster than the ocean
