Research has shown that Saturn is 95 times the mass of the Earth, and it is 765 times the volume of the Earth. What explains why the volume is much larger than the mass difference to the Earth? Please remember to write using your best grammar.
The reason for this is because Saturn is less dense than Earth.
Explain why Mercury has very little atmosphere surrounding the planet. Please remember to write using your best grammar.
There are many reasons why mercury has little atmosphere. One reason is the heat from the sun, which carries out any gases found in mercury, which in return makes its atmosphere very thin.
