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

Answer

Brief Explanations:

Gravity pulls materials together causing compaction. Compaction generates heat, leading to melting and density - based movement (sinking and rising) of materials which helps in layer formation in protoplanets. Radioactive decay is not directly caused by gravity. Gravity doesn't absorb or release heat in the ways described in the other options.

Answer:

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