What part of the mantle is the asthenosphere found?
The asthenosphere lies in, and is the upper ductile part of, the mantle. It is the layer directly underneath the lithosphere; the layer composed of the crust and uppermost rigid mantle.
What states that Earth's crust and rigid upper mantle are broken into enormous slabs called plates that move slowly over Earth's surface?
The theory of plate tectonics.
What is the semi rigid layer of solid rock that flows very slowly called?
The rock layer beneath the Earth's surface that slowly flows is the mantle. (Given enough time, all rocks, even the most solid, will flow through molecular motion.)The mantle is a slowly convecting layer of rock which flows in order to transfer heat from the core to the Earth's surface. It is this convection that drives the movements of the continents and can cause volcanic mountains to form.The athenosphere is the highly viscous, mechanically-weak and ductilely-deforming upper mantle of the Earth. It is the zone upon which the great rigid and brittle lithospheric plates of the Earth's crust move about. However, the whole mantle is flowing, albeit very slowly.
What is a area of rigid blocks of earth's crust upper mantle?
plates
What is the rigid zone above the asthenosphere that includes the crust and upper mantle?
The lithosphere
What is the least rigid part of the mantle?
The upper mantle is less rigid because the pressure is lower
Why is the lower mantle more rigid and dense then the asthenosphere in the upper mantle?
The lower mantle is older and cooler than the upper mantle. Thank you for reading this I'm comment if you like one direction(: hehe
Is the lithosphere liquid?
No. The lithosphere consists of the crust and the rigid uppermost part of the mantle. Therefore it is solid.
What is the theory that states that the earth's crust is divided into rigid plates that slowly move across the upper mantle?
plate tectonics.
What part of the mantle is the asthenosphere found?
The asthenosphere lies in, and is the upper ductile part of, the mantle. It is the layer directly underneath the lithosphere; the layer composed of the crust and uppermost rigid mantle.
Which layer of the Earth is rigid but molten?
A substance can't be rigid and molten. I wonder if you are confused by the lower mantle, also called the asthenosphere, which is not molten but can flow. In any case the layers are:The crust, which is solid rock and therefore rigid, though of course sufficient force will deform or fracture it.The mantle, which is essentially solid though the lower parts can flow much like asphalt under extreme pressure.The outer core, which is liquid iron and nickel.The inner core, which is solid iron and nickel.
What are the three layers of the moon?
1.CORE The very heart of the moon. 2.LOWER MANTLE The asthenosphere, from where the majority of moonquakes emanate. 3. UPPER MANTLE The lithosphere which is the most rigid part of the mantle
What states that Earth's crust and rigid upper mantle are broken into enormous slabs called plates that move slowly over Earth's surface?
The theory of plate tectonics.
What is a rigid layer made up of the uppermost part of the mantle and crust?
The rigid layer that is the upper mantle and crust is called the lithosphere.

Plates are composed of earths crust and?
dirt and rigid rocks
Is the mantle made of rigid material?
According to plate tectonic theory and observations of seismic waves, the upper mantle is solid and more dense than the crust. At greater depth, the rigidity abruptly decreases and it becomes very flexible, but not liquid.
