The mantle is a part of an astronomical object. The interior of the Earth, similar to the other terrestrial planets, is chemically divided into layers. The mantle is a highly viscous layer between t...

Hotspot (geology) - Wikipedia, the free encyclopedia

|
In geology, a hotspot is a location on the Earth's surface that has experienced active volcanism for a long period of time. J. Tuzo Wilson came up with the idea in 1963 that volcanic chains like the...

The earth is divided into four main layers: the inner core, outer core, mantle, and crust. The core is composed mostly of iron (Fe) and is so hot that the outer core is molten, with about 10% sulphur (S). The inner core is under such extreme pressure that it remains solid.

The pressure and temperature of the earth increases as one moves closer to the center. First comes the mantle, said to go down 2,900 kilometers; it's temperature is about 870C. The outer core has a very high temperature and ranges from abou...

Lower mantle: 49.2% of Earth's mass; ... The continental lithosphere is about 150 kilometers (93 miles) thick with a low-density crust and upper-mantle that are permanently buoyant. Continents drift laterally along the convecting system of the mantle away from hot mantle zones toward cooler ones, a process known as...

A rare form of magmatic rock known as komatiite was formed in the Earth's mantle at temperatures around 1700 degrees Celcius in the Archaean age, ... The first "hot-melting" model assumes the komatiite was formed through the melting of a mantle source at temperatures up to 500 degrees C hotter than today's mantle temperature.

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.
