What Best Describes the Composition of the Asthenosphere

A magma chamber forms beneath the ridge axis. Although the asthenosphere represents no more than six percent of the mantle the mobility of this layer allows the overlaying lithosphere.

The asthenosphere is the liquid outer core of Earth.

. Question 19 1 point Which of the following best describes the asthenosphere. How do we know that the outer core of Earth is liquid. Asthenosphere The asthenosphere is made of very viscous ductile semi-solid material on which the lithosphere moves.

Molten rock or magma is actually rare in earths interior - only the outer core is hot enough to be above the melting point for material of that composition under that amount of pressure. It is a solid that can behave like a liquid and it is about 440km thick. The ____ process that the bodies of our solar system formed at essentially the same time from a rotating.

The asthenosphere is a solid but is hot and weak and therefore can flow over long timescales. The asthenosphere is a liquid layer in the mantle. Matter in the Asthenosphere is in the molten or semi-molten state.

This chemical composition is almost identical to the lower layer of the earth or mesosphere. The asthenosphere is solid upper mantle material that is so hot that it behaves plastically and can flow. The lithosphere is the brittle crust and uppermost mantle.

This is because its temperatures can peak at 3000 degrees Celsius. It is a solid that can behave like a liquid and it is about 440km thick. The ____ is the relatively rigid zone above the asthenosphere that includes the crust and upper mantle.

We can see the crust granitic in composition. The asthenosphere is just another name for tectonic plates. The asthenosphere is responsible for the renewal and expansion of the ocean floor.

True or falsethe outer core is the last layer of. The asthenosphere beneath diverging plates rises and melts 2. The lithosphere moves over the asthenosphere due to its flexible property.

Asthenosphere The asthenosphere is made of very viscous ductile semi-solid material on which the lithosphere moves. The lithosphere rests on the asthenosphere. What is the composition of asthenosphere.

This material makes up the composition of the continental crust This material makes up the composition of the oceanic crust This is the thicker part of the crust with a thickness of 10-70 km. The rigid outer mechanical layer of Earth consisting of the crust and outermost solid part of the mantle. The dynamic geology of Earths crust is informed by plate tectonics.

The best description of Earths mantle is it is made up of rock so hot that it flows. The asthenosphere tends to flow slowly. Tectonic plates of rigid and brittle _____ move over a softer and.

Which of these best describes the asthenosphere inside of the Earths mantle. This layer is also called the asthenosphere. Asthenosphere extends from the base of lithosphere up to 660 km below the surface.

Internally the Earth consists of spherical shells with different compositions and densities. A soft plastic partially-molten mechanical layer in Earth located below the lithosphere. The asthenosphere has a fluid-like properties with high viscosity that the crust rides on.

It is a solid that can behave like a liquid and it is about 440km thick. Asthenosphere is a partially melted layer of earth and is a part of upper mantle. Crust describes the outermost shell of a terrestrial planet.

In contrast lithospheric rocks contain more silica but less aluminium sodium and potassium. The asthenosphere inside of the earths mantle is not quite liquid or solid it is similar in texture to toothpaste. The lithosphere is rigid and commonly deforms in a brittle manner.

What is a soft layer just below the lithosphere. The asthenosphere is located below the lithosphere and is made of softer and hotter rock on which the lithosphere moves. The oceanic crust however is basaltic.

It is a solid that can behave like a liquid and it is about 440km thick. Earths crust is generally divided into older thicker continental crust and younger denser oceanic crust. It is formed by iron and magnesium silicates.

What are two characteristics of the asthenosphere. This Earths mantle has a thickness that reaches 2900 kilometers to wrap up the Earths core. Determine which statement best describes what happens as a rock is moved from point A to point B.

What best describes the physical nature of the earths lithosphere and the asthenosphere. This best describes the asthenosphere. The asthenosphere is composed of rock material.

AnswerCrust describes the outermost shell of a terrestrial planet. It is composed of partial melt and rocks. The characteristics of the asthenosphere are that it is composed of semi-fused and solid materials.

Because the asthenosphere is composed of weak hot and dense rock the cold rigid less dense lithospheric plates are capable of moving on it. The asthenosphere is a solid but it can flow like toothpaste. A shadow zone exists where S waves do not arrive on the side of Earth opposite the focus of an earthquake.

Which of the following best describes the asthenosphere. This property tells us that the asthenosphere is composed of partially molten rock slushlike material consisting of solid particles with liquid occupying spaces in between. The lithosphere rides on the asthenosphere.

The amount of silica in the magma increases and the magma composition changes accordingly.
