The Earth is made up of a total of 7 layers which are- crust, lithosphere (crust and uppermost mantle), asthenosphere (upper mantle directly below the lithosphere), lower mantle, outer core and ...

Below the lithosphere is the asthenosphere — a viscous layer kept malleable by heat deep within the Earth. It lubricates the undersides of Earth's tectonic plates, allowing the lithosphere to move.

Thanks to these studies, we now know the five layers of the atmosphere are the troposphere, stratosphere, mesosphere, thermosphere and exosphere (see graphic). Together, these layers protect us ...

One discovery that ought to be on everyone's rundown is plate tectonics - the description of how the rigid outer shell of our planet (its lithosphere) moves and is recycled. The theory celebrates ...

Aa Aa Aa Biogeochemical cycles describe pathways by which chemical elements move through both biotic (the biosphere) and abiotic compartments (the atmosphere, hydrosphere, and lithosphere ...

Researchers from Japan suggest that the oceanic asthenosphere retains water. This difference in water content between the lithosphere and asthenosphere can account for the sharp drops in shear ...

I am particularly interested in the role of melts at structural, rheological, and/or chemical boundaries in the Earth, such as the lithosphere-asthenosphere boundary, the transition zone (410-660 km), ...

The plates make up Earth's outer shell, called the lithosphere. (This includes the crust and uppermost part of the mantle.) Churning currents in the molten rocks below propel them along like a ...
