Why are there so many more craters on the moon, than on Earth?

With no weather, weathering and erosion do not erase the craters.

300

Explain nuclear fusion.

when the temperature rises in a star's core, the elements or atoms start to fuse with each other

generating tremendous amounts of energy.

300

Explain why an atmosphere can be a good thing for a planet.

Shields us from incoming debris - meteors, asteroids, etc.  It also blocks harmful radiation from the Sun.

300

How is a space telescope better than a telescope on Earth?

It can collect different radiation type not blocked by the atmosphere.
