What type of planets are closest to the sun and have a rocky surface?

Understand the Problem

The question is asking to identify which type of planets are closest to the sun and are characterized by having a rocky surface. It provides multiple choice answers that allow for a specific categorization of planets.

More Information

Terrestrial planets are made up mostly of silicate rocks or metals and have a solid surface. They differ from gas giants, which are composed largely of hydrogen and helium.

Tips

A common mistake is confusing terrestrial planets with gas giants, which have no solid surface and are mostly composed of gases.
