Chapter 31, Problem 13TE

To determine

The reason of the large spaces of blue sky between the cumulus clouds.

Answer to Problem 13TE

The temperature fluctuation of the air is the reason for the large spaces of blue sky between the cumulus clouds.

Explanation of Solution

The air present in the atmosphere has a different temperature at different places. As the temperature varies, the density of the air also varies. This variation of density causes less dense clouds at some places in the sky.

There are cumulus clouds distributed in the atmosphere in such a way that there are some spaces present in between the clouds. The main reason behind this is the temperature fluctuations of the air.

Conclusion:

Therefore, the temperature fluctuation of the air is the reason for the large spaces of blue sky between the cumulus clouds.
