which best explains how gravity contributes to the formation of layers in protoplanets?\no gravity attracts materials and causes compaction, which produces heat and leads to the melting, sinking, and rising of materials.\no gravity causes materials to undergo radioactive decay, which produces heat and leads to the melting, sinking, and rising of materials.\no gravity absorbs heat, which cools materials and causes them to sink and rise.\no gravity releases heat into space, which cools materials and causes them to sink and rise.

Answer

Brief Explanations:

Gravity attracts materials in protoplanets. This compaction generates heat, leading to melting. Denser materials sink and less - dense ones rise, forming layers. Radioactive decay is not directly related to gravity in this context. Gravity doesn't absorb or release heat in the described way for layer - formation.

Answer:

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