Question

Which best explains how gravity contributes to the formation of layers in protoplanets? Gravity attracts materials and causes compaction, which produces heat and leads to the melting, sinking, and rising of materials. Gravity causes materials to undergo radioactive decay, which produces heat and leads to the melting, sinking, and rising of materials. Gravity absorbs heat, which cools materials and causes them to sink and rise. Gravity releases heat into space, which cools materials and causes them to sink and rise.

Answer 1

Answer:

A

Explanation:

Answer 2

The sentence that best explains how gravity contributes to the formation of layers in protoplanets is ; (  A ) Gravity attracts materials and causes compaction, which produces heat and leads to the melting, sinking, and rising of materials

  Gravity is the force that attracts bodies with masses towards each other. bodies with larger masses posses greater forces of gravity.  therefore

from the options gravity attracts materials and causes compaction which produces heat and leads to the melting, sinking and rising of materials.

Hence we can conclude that Gravity attracts materials and causes compaction, which produces heat and leads to the melting, sinking, and rising of materials
