The asthenosphere begins at around 100-150 km depth in the Earth. This is below the lithosphere, which consists of the crust and the uppermost mantle (the plates in plate tectonics).
The asthenosphere is in the mantle, but it is still unclear how much of the mantle (which goes down to a depth of ~2900 km) is actually part of the asthenosphere.

Do cirrus clouds form near or far from earths surface?
They form far above the earths surface.
When large masses of magma solidify far below earths's surface they form igneous rocks that have a?
Coarse-grained texture
What depth does the asthenosphere start and how far down does it extend?
The asthenosphere is the layer of Earth that lies at a depth 60-150 mi (100-250 km) beneath Earth's surface.
How far below the earths surface do earthquakes occur?
The Lithosphere is not far down at all. Actually, the lithosphere is the solid rocky outer part of the earth. The lithosphere is about 100 km deep in most places.
How far does the straosphere extend above earths surface?
The stratosphere's upper limit is about 20 miles above sea level.
How far away is the asthenosphere?
The asthenosphere, which is a soft plastic, is between approximately 62 and 124 miles below the surface. It is just below rigid lithosphere.
What is an earthquake that may be far below the earths surface?
it is called the interior
What is the texture of igneous rocks that form far below earths surface?
Course grained texture.

When large masses of magma solidify far below earths surface and large crystals form what do they exhibit?
The crystals may display a "Crescumulate texture".
What depth does the asthenosphere start and how far down does it extend?
The asthenosphere is the layer of Earth that lies at a depth 60-150 mi (100-250 km) beneath Earth's surface.
