Best Answer: The crust or lithosphere is the coolest layer by far. It is what we live on. It is in the vicinity of 0 degrees C (varying with depth and location). The mantle is about 1,700 miles (2,750 km) thick.
The Earth's crust is an extremely thin layer of rock, like the skin of an apple in relative terms. It amounts to less than half of 1 percent of the planet. But the crust is exceptionally important, and not just because we live on it.The crust can be thicker than 80 kilometers in some spots, less than one kilometer in others. Underneath it is the mantle, a layer of rock some 2700 kilometers thick that accounts for the bulk of the Earth.The crust is primarily made of granite and basalt while the mantle beneath is made of peridotite.he Earth's crust is an extremely thin layer of rock, like the skin of an apple in relative terms.
