Which statements describe earth? check all that apply. it is an outer planet. it is a terrestrial planet. it was formed from gas and dust. it has a thick atmosphere of hydrogen and helium. it was formed in a debris disk from colliding planetesimals.

The correct answers are:

- It is a terrestrial planet;

The Earth is a terrestrial plant, and the main reason why it is classified as such is because it has a hard, rocky shell. The terrestrial planets seem to form closer to the Sun, or rather the star, while the gas planets further away from it.

- It has formed from gas and dust;

The most accepted theory about the formation of the Earth is that it formed from heated gas and dust, otherwise known as nebula. Under the gravity the material collapsed on itself, the particles started to merge with one another, and over time they became a large body, which under the influence of the spinning in a roughly circular manner, got the rounded shape.
