what is the source of heat generated by the core to the mantle?
a. gases
b. decayed radioactive
c. molten
d. molten metal
Answer (1)
B. decayed radioactive The heat that comes from the Earth's core to the mantle is mostly from radioactive decay. Inside the Earth, there are elements like uranium and thorium that slowly break down. When they do, they release heat. This heat helps keep the inside of the Earth very hot. It's one of the main reasons why the core and mantle stay warm for billions of years.
