which of the following is responsible for about half of the heat generated by earths core? a) frictional heating b) radioactive decay of elements c) residual heat from earths formation d) sunlight
Answer
Answer:
B. Radioactive decay of elements
Brief Explanation:
Radioactive decay in Earth's core generates about half of its heat. Frictional heating is not a major source. Residual heat from formation contributes but is less significant. Sunlight does not heat the core.
