It makes up the bulk of the Earth, accounting for two-thirds of the planet's mass. The mantle starts about 30 kilometers down and is about 2,900 kilometers thick. 01. WebThe Mantle The mantle is the layer located directly under the sima. It is the largest layer of the Earth, 1800 miles thick. The mantle is composed of very hot, dense rock. This layer of rock even flows like asphalt under a heavy weight. This flow is due to great temperature differences from the bottom to the top of the mantle.
