Question

identifying heat production processes during earths formation
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: When materials collided during Earth's formation, kinetic energy was converted into heat.
• Compaction of materials: As materials were compressed together, potential energy was transformed into heat.
• Radioactive decay: Unstable atomic nuclei decay, releasing energy in the form of heat.
• Sinking of high - density metals: The movement of high - density metals (like iron) towards the center of the Earth involved friction and release of gravitational potential energy as heat.
• Cooling of low - density metals: Cooling is a process of heat loss, not heat production.

Answer:

collision of materials, compaction of materials, radioactive decay, sinking of high - density metals.
