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 released energy as heat. Compaction of materials under pressure generated heat. Radioactive decay of unstable isotopes is a continuous heat - source. Sinking of high - density metals also released gravitational potential energy as heat. Cooling of low - density metals does not produce heat but rather releases it as they solidify.

Answer:

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