Question

question #13
the diagram shows the effect of solar energy on both land and sea on a hot, sunny day.
why is the air over the sea cooler even on a hot, sunny day?
a water has the ability to regulate its own temperature.

b water keeps flowing which prevents the water from heating up at all.

c water needs to absorb a lot of solar energy to warm up.

d water absorbs the suns energy but does not transmit it.

Explanation:

Water has a high specific heat capacity, meaning it requires a large amount of thermal energy to increase its temperature. On a hot, sunny day, while land heats up quickly with the same solar input, water must absorb far more solar energy to warm, so the air above it stays cooler. Option A is vague; option B is incorrect because water does heat up, just more slowly; option D is wrong because water does transmit absorbed energy (it just warms slowly).

Answer:

C. Water needs to absorb a lot of solar energy to warm up.
