SOLAR SYSTEM

Detailed explanation-1: -It is mostly solid rock, but less viscous at tectonic plate boundaries and mantle plumes. Mantle rocks there are soft and able to move plastically (over the course of millions of years) at great depth and pressure. The transfer of heat and material in the mantle helps determine the landscape of Earth.

Detailed explanation-2: -The mantle lies below the crust and is up to 2900 km thick. It consists of hot, dense, iron and magnesium-rich solid rock. The crust and the upper part of the mantle make up the lithosphere, which is broken into plates, both large and small. To learn more about these plates see the Plate Tectonics page.

Detailed explanation-3: -Below the crust is the mantle, a dense, hot layer of semi-solid rock approximately 2, 900 km thick. The mantle, which contains more iron, magnesium, and calcium than the crust, is hotter and denser because temperature and pressure inside the Earth increase with depth.

Detailed explanation-4: -Magma is a molten and semi-molten rock mixture found under the surface of Earth. This mixture is usually made up of four parts: a hot liquid base, called the melt; minerals crystallized by the melt; solid rocks incorporated into the melt from the surrounding confines; and dissolved gases.

Detailed explanation-5: -The mantle is dense and mostly solid rock. Layer 4. The crust is a thin rock material. In the core, the temperature reaches to 9000 degrees F, hotter than the sun’s surface!
