How is the earth's crust different from the mantle and core?

Best Answers

The Earth's mantle is made up of semisolid rocks. While different layers of the mantle are made of different kinds and densities of rocks, all are more dense than the crust, and the entire mantle is hot. The temperature of the mantle is hottest nearest the core, and cooler near the crust. read more

Earth's mantle is thought to be composed mainly of olivine-rich rock. It has different temperatures at different depths. The temperature is lowest immediately beneath the crust and increases with depth. read more

Earth's crust is a much different place than the mantle. The mantle is a lot thicker than the crust. The crust is only 6-15 miles deep and the mantle is thousands of miles beneath the crust. read more
