How does insulation keep building cool in the summer?​
exis [7]

Answer:

It slows down the entry of heat through the walls and ceiling.  

Explanation:

Insulation is a poor conductor of heat.

Thus, it takes a long time for the heat of the sun's rays to penetrate to the inside of the building.

If the building was cool to start with, insulation will help it stay cool longer.

Which statement about Earth's rotation and its revolution is correct?
Allisa [31]

Answer:

It takes Earth longer to revolve around the sun than to rotate on its axis.

Explanation:

The vocabulary can be tricky in this question. It is important to remember that the term revolution refers to something moving around a fixed point. In this case, the earth is the object revolving around sun which is the fixed point in the frame of reference.

Now, the earth rotates at a constant speed around its axis. This is what causes the day/night cycle. The earth itself is spinning, therefore we use the term rotate.
