Webb17 apr. 2024 · Which layer is the most solid? mantle. The mantle is the mostly-solid bulk of Earth’s interior. The mantle lies between Earth’s dense, super-heated core and its thin outer layer, the crust. The mantle is about 2,900 kilometers (1,802 miles) thick, and makes up a whopping 84% of Earth’s total volume. Webb25 apr. 2024 · The density of the lithosphere varies depending on temperature, depth and age. At about 50 kilometers (30 miles) below the Earth's surface, density measurements reach 200,000 pounds per square inch (13,790 bars). Due to the pressure from the above crust and mantle, lithospheric density generally increases as both age of the surrounding …
