The Asthenoshere is beneath the lithosphere. It is a weak layer ( from the greek work aesthenos meaning weak) of heat softened, relatively weak, slow flowing yet still solid rock located in the upper mantel from about 100 to 350 kilometers (60-220 miles) beneath the earth's surface. It is within the lithosphere and asthenosphere that large scale geological processes take place.
The mantle is divided into the upper mantle, transition zone, and lower mantle. The upper mantle is beneath the lithosphere, the transition zone lies between the upper and lower mantle, and the lower mantle extends to the outer core.
Inner core Outer core Lower mantle Upper mantle Astenosphere Moho Lithosphere Crust
The three sub layers of the mantle are the lithosphere, asthenosphere, and mesosphere. The lithosphere is the rigid outer layer consisting of the crust and upper part of the mantle. The asthenosphere is a partially molten layer beneath the lithosphere that allows for the movement of tectonic plates. The mesosphere is the lowermost and solid part of the mantle.
Convection, the heating and cooling of the astenosphere, a ridge push, at mid ocean ridges oceanic lithosphere slides down due to gravity, slab pull, oceanic lithosphere sinks in the astenosphere and pulls the rest of the tectonic plate with it.
the asthenosphere is very bendable yet solid and "weak" yet it is not as bendable as laffy taffy because it is still solid and obviously not that bendable because it is a layer of the EARTH so it is still very hard. if you kicked it, you would brake your foot!
Astenosphere contain pyroxenes and olivines.
assorted gases
lithosphereic plates are the cooler plates. they help everyone with their convection.
the material in the astehnosphere can flow slowly and the lithosphere flows on top of the astenosphere HOPE I HELPED!!
A common definition of the lithosphere-astenosphere boundary is a thermal one. The astenosphere begins when 1300°C are reached. The lithosphere (containing the crust and the lithospheric mantle) is thus cooler than 1300°C but the lower portion of the lithosphere is still very hot (maybe 500-900°C or so). From the asthenosphere down towards the core the temperature keeps increasing and at the core the mantle has an estimated temperature of 4000°C.
Convection currents are located in the astenosphere in boiling water and lots of other places
The mantle is divided into the upper mantle, transition zone, and lower mantle. The upper mantle is beneath the lithosphere, the transition zone lies between the upper and lower mantle, and the lower mantle extends to the outer core.
The asthenosphere is approximately 100-200 kilometers thick beneath the Earth's crust. It is a semi-plastic layer of the mantle that lies below the lithosphere and plays a key role in plate tectonics and mantle convection.
Inner core Outer core Lower mantle Upper mantle Astenosphere Moho Lithosphere Crust
The asthenosphere is partially molten and has a lower viscosity compared to the lithosphere above it. This low viscosity allows the lithosphere plates to move and glide over the asthenosphere. The plasticity of the asthenosphere enables convection currents to occur, which in turn can drive the movement of the lithosphere plates.

The asthenosphere is a partially molten layer beneath the lithosphere that allows for the movement of tectonic plates. The mesosphere is the lowermost and solid part of the mantle.
There is no "driving force". The tectonic plates created an oceanic/oceanic subvergent boundary where underwater volcanoes formed. The magma comes up through faults and cracks in the lithosphere from the astenosphere and comes out of the volcanoes. I suppose you could say the "driving force" is the heat from the center of the earth heating the rock to a liquid state.
