What is the mantle of the Earth? Why is Earth's mantle solid? What is the upper mantle called? What is present in the mantle that can melt the crust that moves downward? How does the mantle affect the Earth's crust? The convection cycles of the mantle are the main cause of the move...
Like other supervolcanic areas, Yellowstone sits on a long-active tectonic zone, a weakened and thinned crust overlying a 2,500 F (1,370 C) magma dome rising from the upper mantle. This dome has melted and broken into the crust to create two magma chambers roughly 5-7 miles (8-11 ...
The troposphere, the bottommost layer of Earth’s atmosphere, is the densest of the five atmospheric layers and extends from ground level up to about 10 kilometers in altitude. This is the layer where humans live and breathe, as it contains the air we depend on for survival. The tropospher...
Naturaldiamonds are formeddeep underground — typically 100 miles or so below the Earth's surface in a layer called the upper mantle — and brought to the surface by volcanic eruptions. Certain conditions are required for diamonds to form, namely intense pressure and heat. Temperatures can range...

Melt in the Crust and Upper Mantle: How Much, Where, for How Long, and What Significance for Geodynamics?
According to science, the carbon that makes diamonds comes from the melting of pre-existing rocks in the Earth’s upper mantle. There is an abundance of carbon atoms in the mantle. Temperature changes in the upper mantle forces the carbon atoms to go deeper where it melts and finally ...
A subduction zone is a collision between two of Earth's tectonic plates, where one plate sinks into the mantle underneath the other plate.
A tunic is a simple, often sleeveless garment that extends from shoulders to knees, used in various ancient and modern contexts. A mantle, on the other hand, is a loose, outer cloak worn over other clothes, often signifying status or used for warmth. ...
