Which Of The Following Is The Rigid Solid Layer Of The Upper Mantle That Is Connected To The Cross?

The lithosphere is composed of both the crust and the portion of the upper mantle that behaves as a brittle, rigid solid. The lithosphere is the outermost mechanical layer, which behaves as a brittle, rigid solid.

Which of the following is the rigid solid layer of the upper mantle that is connected to the crust asthenosphere atmosphere lithosphere mesosphere?

Earth’s

lithosphere

. Earth’s lithosphere includes the crust and the uppermost mantle, which constitutes the hard and rigid outer layer of the Earth. The lithosphere is subdivided into tectonic plates. The lithosphere is underlain by the asthenosphere which is the weaker, hotter, and deeper part of the upper mantle.

Which of the following is the rigid solid layer of the upper mantle that is connected to the crust 3 points a asthenosphere B atmosphere c lithosphere D mesosphere?

Cutaway Earth

The

lithosphere

is the rocky outer part of the Earth. It is made up of the brittle crust and the top part of the upper mantle. The lithosphere is the coolest and most rigid part of the Earth.

Which of the following is the rigid solid layer of the upper mantle that is connected to the crust?

Lithosphere

, rigid, rocky outer layer of the Earth, consisting of the crust and the solid outermost layer of the upper mantle. It extends to a depth of about 60 miles (100 km). It is broken into about a dozen separate, rigid blocks, or plates (see plate tectonics).

Which part of the mantle is the upper layer that is rigid?

The lithosphere

is the rocky outer part of the Earth. It is made up of the brittle crust and the top part of the upper mantle. The lithosphere is the coolest and most rigid part of the Earth.

Is the asthenosphere solid or liquid?

2. Asthenosphere –The asthenosphere is made of very viscous, ductile, semi-solid material on which the lithosphere moves. It is a

solid that can behave like a liquid

, and it is about 440km thick.

What are the characteristics of the upper mantle?

The upper mantle extends from the crust to a depth of about 410 kilometers (255 miles). The upper mantle is

mostly solid, but its more malleable regions contribute to tectonic activity

. Two parts of the upper mantle are often recognized as distinct regions in Earth’s interior: the lithosphere and the asthenosphere.

What is Earth’s hottest layer?

The core

is the hottest, densest part of the Earth. Although the inner core is mostly NiFe, the iron catastrophe also drove heavy siderophile elements to the center of the Earth.

Which is the most thinnest layer?

*

Inner core

It is the thinnest layer of the Earth. *The crust is 5-35km thick beneath the land and 1-8km thick beneath the oceans.

Which is the hottest layer of the atmosphere?

The thermosphere

is often considered the “hot layer” because it contains the warmest temperatures in the atmosphere. Temperature increases with height until the estimated top of the thermosphere at 500 km. Temperatures can reach as high as 2000 K or 1727 oC in this layer (Wallace and Hobbs 24).

What are the two types of crust?

Earth’s crust is divided into two types:

oceanic crust and continental crust

. The transition zone between these two types of crust is sometimes called the Conrad discontinuity. Silicates (mostly compounds made of silicon and oxygen) are the most abundant rocks and minerals in both oceanic and continental crust.

Is the lower mantle solid or liquid?

The lower mantle is the

liquid inner layer

of the earth from 400 to 1,800 miles below the surface. The lower mantle has temperatures over 7,000 degrees Fahrenheit and pressures up to 1.3 million times that of the surface near the outer core.

What is called the upper layer of lithosphere?

The upper most layer of the lithosphere is called “

CRUST”

Is the mantle rigid or plastic?

Why is the mantle the thickest layer?

Below the crust is the mantle, a dense, hot layer of semi-solid rock approximately 2,900 km thick. The mantle, which contains more iron, magnesium, and calcium than the crust, is

hotter and denser because temperature and pressure inside the Earth increase with depth

.

What color is the mantle?

In grade-school science textbooks, Earth’s mantle is usually shown in a

yellow-to-orange gradient

, a nebulously defined layer between the crust and the core. To geologists, the mantle is much more than that. It’s a region somewhere between the cold crust and the bright heat of the core.
