Question

which processes produced heat that contributed to the formation of earths different layers? check all that apply. collision of materials compaction of materials cooling of low - density metals radioactive decay sinking of high - density metals

Explanation:

• Collision of materials during Earth's formation generated heat. Compression of materials under gravitational forces also produced heat. Radioactive decay is a continuous heat - producing process in Earth's interior. Sinking of high - density metals releases gravitational potential energy as heat. Cooling of low - density metals is not a heat - producing process but a heat - losing one.

Answer:

• collision of materials
• compression of materials
• radioactive decay
• sinking of high - density metals
