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 contains the lower mantle?
The mantle extends to the core-mantle interface at approximately 2900 km depth. Thus, the mantle contains the lower portion of the lithosphere, the asthenosphere, and the mesosphere. The crust is made of the upper portion of the lithosphere.
What is the correct order starting from the surface of earth layers?
lithosphere, asthenosphere, mesosphere, outer core, inner core
What is the correct order starting from the surface Earth's layers?
lithosphere, asthenosphere, mesosphere, outer core, inner core
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 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.
How do cyclones affect Asthenosphere?
They don't. Hurricanes are an atmospheric phenomenon. Their effects underground only go as far as recharging groundwater supplies, which don't come anywhere close to the depth of the asthenosphere.
What is the range of the depth of the asthenosphere?
The asthenosphere is the lower portion of the Earth's mantle. Its temperature ranges from 1000 degrees Celsius to 2500 degrees Celsius.
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.
Characteristics of the asthenosphere?
The asthenosphere is the region of the upper mantle of the Earth. With a base depth of about 700 kilometers, it is involved in plate tectonic movement and isotactic adjustments, seismic waves pass through slowly and a small percentage of melt.

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 is the order of the earth's layers starting from the surface?
lithosphere, asthenosphere, mesosphere, outer core, inner core
What is the order starting from the surface of earths layers?
lithosphere, asthenosphere, mesosphere, outer core, inner core
What is the order (starting from the surface) of earth's layers?
lithosphere, asthenosphere, mesosphere, outer core, inner core
What contains the lower mantle?
The mantle extends to the core-mantle interface at approximately 2900 km depth. Thus, the mantle contains the lower portion of the lithosphere, the asthenosphere, and the mesosphere. The crust is made of the upper portion of the lithosphere.
What are the starting and ending point of circle?
A circle has no starting or ending point of a circle. Hope this helps!
