Question

Which processes produced heat that contributed to the formation of Earth’s different layers? Check all that apply.

Answer 1

Answer:

There are three main sources of heat in the deep earth: (1) heat from when the planet formed and accreted, which has not yet been lost; (2) frictional heating, caused by denser core material sinking to the center of the planet; and (3) heat from the decay of radioactive elements.

Answer 2

Complete Question:

Which processes produced heat that contributed to the formation of Earth's different layers? Check all that apply.

A. Collision of materials

B. Compaction of materials

C. Cooling of low-density metals

D. Radioactive decay

E. Sinking of high-density metals

Answer:

A .collision of materials

B. compaction of materials

D. Radioactive decay

These are the processes produced heat that contributed to the formation of Earth's different layers.

Explanation:

• The collision of materials, the compacting of materials, and radioactive activity are some of the processes that generate heat and were involved in the development of the many layers of the Earth.
• The mantle, crust, and core are the three distinct layers that make up the Earth.
• They are constructed from solid rock, typically granite and basalt. The radioactive decay of materials found in the crust of the Earth produces thermal energy.
• It should be mentioned that around 50% of the Earth's internal heat is produced by radioactive decay.

Collision of materials:

• A collision is any situation in which two or more bodies quickly exert forces on one another.

Compaction of materials:

• Compaction is a mechanical and artificial process that rapidly reduces the volume of soil by forcing air holes out of the ground, increasing the soil's density in the process.

Radioactive decay:

• Ionizing radiation is released as a result of radioactive decay.
