What is the temperature at the bottom of the ocean? What is the hottest layer of the Earth's atmosphere? Which layers make up the lithosphere of Earth? What is the pressure of the Earth's mantle? What is the hottest layer of the Earth? Which layer of the Earth are the lithosphere and...
Learn about the layers of the Earth and see which is the thinnest layer of Earth. Explore the Earth's crust, mantle, and the Earth's core and see...
The ocean is made up of layers. The topmost area, which receives the most sunlight, has the warmest temperatures. Each layer below the surface becomes incrementally cooler the deeper you go. Answer and Explanation: Learn more about this topic: ...
temperatures, the deeper part of the mantle is more plastic than the outer portion. This area, known as the asthenosphere, is capable of flowing slowly and may haveconvection currents. When the Earth's plates shift, the hard lithosphere is floating and moving on top of the softer ...

Earth, third planet from the Sun and the fifth largest planet in the solar system in terms of size and mass. Its single most outstanding feature is that its near-surface environments are the only places in the universe known to harbor life. Learn more ab
one may use seismic discontinuities and the associated solid-state phase changes. This classical method requires specification of the mantle composition, which is usually taken to be pyrolite (Ringwood, 1962). Well-defined discontinuities at depths of 410 and 660km have been linked to the olivine...
Ultra-high pressure (UHP) metamorphismis defined as the mineralogical and structural modification of predominantly continental and minor associated oceanic crustal protoliths and associated mafic-ultramafic rocks at mantle pressures generally in the range of 2.7–5.0GPa (90–170km) and temperatures about...
In the framework of dynamical modelling of the geoid, we have estimated basic features of the radial profile of temperature in the mantle. The applied parameterization of the geotherm directly characterizes thermal boundary layers and values of the thermal gradient in the upper and lower mantle. In...
