The MAIN difference between terrestrial planets and gas giants is.

A) the way they were formed.

B) the shape of their orbits.

C) the level of their density.

D) the plane in which they lie.

Answer:One important difference between the different types of planets would be the gas giants all have more than 12 moons whereas the terrestrial planets all have less than 3 moons. A second difference is that that gas giants are all larger in diameter than the terrestrial planets.

Explanation:

I would say a

C) the level of their density.

Explanation:

Gaseous planets (gas giants) are huge planets made up of large volumes of gaseous materials, with this characteristic we have in the solar system: Jupiter, Saturn, Uranus and Neptune. The terrestrial planets, in turn, are those formed mainly by rocks and metals, have a solid surface without the incidence of rings, as is the case with Mercury, Venus, Earth and Mars.

Although they may differ in several characteristics, the main difference between these two types of planet is the levels of density. Gaseous planets tend to have the lowest density, while terrestrial palettes are denser.
