which best explains how the collisions of materials in space contribute to the formation of layers in protoplanets?\nthe materials undergo decay when they collide, which results in the heating and subsequent melting and rising of materials.\nthe collisions release heat, which results in the heating and subsequent melting, sinking, and rising of materials.\nthe materials undergo decay when they collide, which results in the cooling and subsequent hardening and sinking of materials.\nthe collisions absorb heat, which results in the cooling and subsequent hardening and rising of materials.
Answer
Brief Explanations:
When materials in space collide during protoplanet formation, the collisions release heat. This heat causes materials to melt. Denser melted materials sink and less - dense ones rise, leading to layer formation. Decay is not the main process here, and collisions do not absorb heat but release it.
Answer:
The collisions release heat, which results in the heating and subsequent melting, sinking, and rising of materials.
