Is the lithosphere and asthenosphere boundary above or below the Moho?
The boundary between the asthenosphere and the lithosphere is normally below the Moho (which marks the boundary between the crust and the mantle). The exception to this is below mid-ocean ridges where the moho and the lithosphere / asthenosphere boundary are at the same depth.
What is the relatively soft layer of rock below the lithosphere?
The softer layer below the lithosphere is the asthenosphere. The asthenosphere begins at a depth of approximately 150 km. It has convection currents that arise from the heating and subsequent rising of material from the lower asthenosphere. These convection currents drive the movement of lithospheric plates at the surface, and are the cause of tectonic activity.
What are Asthenosphere and lithosphere?
We speak of the Earth as consisting of three main regions; the crust as the solid outermost part, the inner core at the very center and the mantle in between. Then we give the regions where they come together names and we also subdivide the three main regions and give the subdivisions names.It is the lithosphere and the asthenosphere that are the parts of the surface moving when we talk of continental drift.The lithosphere is outer portion of the Earth. It is composed of the oceanic and continental crust, along with the rigid upper mantle.The asthenosphere is the plastic like upper mantle directly below the lithosphere where rock can move, bend, and deform without breaking. Below that, the mantle become more fluid and is the major part of the volume of the Earth.The inner most part, the core, is only about 15% of the whole Earth.
What is the outer shell of Earth that extends to a depth of 100km?
Lithosphere.
What is the average rate of temperature increase below the earth's surface?
30 degrees Celsius for each kilometer of depth near Earth's surface
What does lithosphere mean in science terms?
lithosphere refers to the rocks of the earths surface and upper mantle or depth of plates. hope that helped

What is the depth below the surface in cm for the crust?
On the Earth's surface, the depth is between 8-64 kilometers.
How many km is the earths lithosphere from the earths surface?
The Earth's lithosphere can vary in depth from 5 km at the ocean ridges to 200 km underneath mountain ranges.
How does temperature change with depth below earths surface?
temperature increases with depth

How far below the earth's surface is the asthenosphere?
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.
What rock can melt at a depth of about below earths surface?
50km
How many km is the Lithosphere?
The lithosphere can be 8 km to about 65km in depth.
What is the apparent depth of an object whose real depth below the water surface is 5 m?
its apparent depth is 1.5m.
Rock can melt at a depth of about what degree below Earth's surface?
100km
What describes how temperature and pressure change with depth below Earth's surface?
Both temperature and pressure increase with depth.
