Question

What elements that plays a vital role in earths internal heat?

Answer 1

Explanation:

major source of Earth's heat is radioactivity, the energy released when the unstable atoms decay. The radioactive isotopes uranium-235 (235U), uranium-238 (238U), potassium-40 (40K), and thorium-232 (232Th) in Earth's mantle are the primary source.

Answer 2

• Radioactivity is a significant source of Earth's heat.
• The energy is released when the unstable radioactive atoms decay.
• However, a variety of sources are responsible for the inner Earth's heat.
• The radioactive isotopes are uranium-235 (235U), uranium-238 (238U), potassium-40 (40K), and thorium-232 (232Th).
• The increased pressure on Earth's interior causes it to compress and thus heat the Earth's interior.
• Heat also comes due to friction when melted material is redistributed within the Earth's surface.
