Answer 2

hey there!! here is your answer..

Answer:

Hey friend!! To answer your question, let me tell you the defenition of wind itself.

Wind is nothing but moving air.

Air has some characteristics too:

1. Hot air rises are its density is lesser, thus it is more lighter and can rise up , and is lighter than its opposite, cool air.

2. Cold air Falls as its density is more, thus it is more heavier and falls to the ground. It is heavier than its opposite, hot air.

Explanation:

Now, following the defenition of wind and characteristics of air:

Your question is:

What causes wind on top of hills and mountains?

a. cool air rising while hot air sinks

b. cool air and hot air hitting each other

c. hot air rising while cool air sinks

d. cool air and rain clouds

As you know, since the top of hills and mountains are at a higher altitide, the air around it will be cooler, as higher the altitude, cooler the air.

So, in the abov scenario, the sun warms up the air, so the cool air becomes warmer.

Now, following the characteristics of air, hot air rises.

this is similar to the land and sea breeze principle.

Since hot air moves up and cool air moves down, it is basically air moving, thus forming wind.

So, the correct answer is option c)hot air rising while cool air sinks.

hope it helped you!!
