What is the zone below the lithosphere that is more plastic?

What is the zone below the lithosphere that is more plastic?

Below the lithosphere within the upper portion of the mantle is a plastic layer of rock called the asthenosphere.

What is the zone below the lithosphere it is more plastic than the lithosphere so it is easier to bend and move?

The asthenosphere is solid upper mantle material that is so hot that it behaves plastically and can flow. The lithosphere rides on the asthenosphere.

Is the asthenosphere more plastic than the lithosphere?

It is more ‘plastic’ than the lithosphere so it is easier to bend and move. The most outer solid portion of the planet Earth.

Is the lithosphere more plastic?

The zone below the the lithosphere it is more ‘plastic’ than the lithosphere so it is easier to bend and move. Places where the sea floor is forced under continental plates.

What is the section of the Earth below the crust?

the mantle
Beneath the crust is the mantle, which is also mostly solid rocks and minerals, but punctuated by malleable areas of semi-solid magma. At the center of the Earth is a hot, dense metal core.

Is the lithosphere plastic?

Lithosphere: includes the crust and upper mantle. Is composed of a rigid solid. Asthenosphere: lower mantle, composed of “plastic solid” akin to playdoh….

Continental Crust	Crust is thicker and composed of light materials; both in color and density.
Oceanic Crust	Crust is thin and composed of more dense materials.

What is plastic plate tectonics?

The Asthenosphere is made up of semi-plastic rock. Since the Lithosphere has a lower density, it floats on top of the Asthenosphere similar to the way in which an iceberg or a block of wood floats on water. The lower mantle below the Asthenosphere is more rigid and less plastic.

Which is more plastic the lithosphere or the zone below?

The zone below the lithosphere. It is more ‘plastic’ than the lithosphere so it is easier to bend and move. The most outer solid portion of the planet Earth. Nice work! You just studied 17 terms!

How are tectonic plates move through the lithosphere?

The movement of tectonic plates is made possible by thermal energy (heat) from the mantle part of the lithosphere. Thermal energy makes the rocks of the lithosphere more elastic. Tectonic activity is responsible for some of Earth’s most dramatic geologic events: earthquakes, volcanoes, orogeny ( mountain -building),

What makes the rocks of the lithosphere more elastic?

Five Spheres. Thermal energy makes the rocks of the lithosphere more elastic. Tectonic activity is responsible for some of Earth’s most dramatic geologic events: earthquake s, volcano es, orogeny (mountain-building), and deep ocean trench es can all be formed by tectonic activity in the lithosphere.

Which is less ductile oceanic or continental lithosphere?

The lithosphere is far less ductile than the asthenosphere. There are two types of lithosphere: oceanic lithosphere and continental lithosphere. Oceanic lithosphere is associated with oceanic crust, and is slightly denser than continental lithosphere. The most well-known feature associated with Earth’s lithosphere is tectonic activity.
