Question

Compare and contrast the general characteristics of a gas giant planet and one of the inner planets (such as Mercury, Earth, Venus or Mars)? Give two differences and one similarity.

Answer 1

The gas planets usually have extremely high gravitational pulls, the surface isn't solid (since its a gas planet), and gas planets are larger than the inner planets. 
Similarities- These planets all have moons and they both revolve around the sun (obviously).


Hope this helps.
