What are 2 facts about lithosphere?

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.

What statements is true about the lithosphere?

Answer: The lithosphere is the solid, outer part of the Earth. The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth’s structure. It is bounded by the atmosphere above and the asthenosphere (another part of the upper mantle) below.

What are the features of lithosphere?

Expert Answer:

• The lithosphere is the solid crust or the hard top layer of the earth.
• It consists of rocks and minerals and is covered by a thin layer of soil.
• It is irregular and consists of various landforms such as mountains, plateaus, plains, valleys etc.

Why is the lithosphere important?

Lithosphere provide us forests, grasslands for grazing land for agriculture and human settlements and also rich source of minerals. The lithosphere contains different types of rocks such as the igneous, sedimentary and metamorphic rocks, it helps to provide the necessary nutrients required to plants.

Why lithosphere is important for the human existence?

Explanation: The lithosphere is largely important because it is the area that the biosphere (the living things on earth) inhabit and live upon. When the biosphere interacts with the lithosphere, organic compounds can become buried in the crust, and dug up as oil, coal or natural gas that we can use for fuels.

What is the lithosphere and why is it important?

Which of the following describe the lithosphere?

Lithosphere is the 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 100 km. It is broken into about a dozen separate, rigid blocks, or plates.

How is lithosphere formed answer?

Due to the cold temperature of space, the surface layer of earth cooled off quickly. It makes a much-cooled rock layer that should be solidifying into the crust. And forms solidified “outer layer of the earth” called lithosphere.

What are some interesting facts about the lithosphere?

Facts about Lithosphere 1: the subdivision. The subdivision of lithosphere is seen based on the tectonic plates. The rigid and hard outer layer of earth is included as lithosphere.

Which is the largest layer of the Earth?

✦ Mantle is the largest layer of Earth (1802 mi thick). It is further divided into upper mantle and lower mantle. The upper part of the mantle is a layer beneath the crust, which is dense and is 31-62 mi (50-100 km) below the Earth’s surface.

Is the lithosphere an elastic or Viscous rock?

Although the rocks of the lithosphere are still considered elastic, they are not viscous. The asthenosphere is viscous, and the lithosphere-asthenosphere boundary (LAB) is the point where geologists and rheologists—scientists who study the flow of matter—mark the difference in ductility between the two layers of the upper mantle.

Which is hotter the asthenosphere or the lithosphere?

Facts about Lithosphere 3: the asthenosphere. The deeper part of the upper mantle is inhabited by asthenosphere located under the lithosphere. The former one has the hotter and weaker characteristics than lithosphere. Lithosphere and asthenosphere have a boundary called Lithosphere-Asthenosphere boundary.
