What is 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.

Why is lithosphere important class 7?

Answer: Lithosphere is the solid crust or the hard top layer of the earth. Lithosphere plays an important role in our life. It provides us forests, grassland for grazing , land for agriculture and human settlements. It is also a treasure of various minerals.

How can we conserve lithosphere?

Also planting the same crop over and over strips vital nutrients in the lithosphere. Overgrazing an process that removes excessive amounts of plants by using animals to strip and erode the topsoil so no plants should be able to grow.

Where is lithosphere?

The lithosphere is the solid, outer part of the Earth. It includes the brittle upper portion of the mantle and the crust, the planet’s outermost layers. The lithosphere is located below the atmosphere and above the asthenosphere. The asthenosphere is made of melted rock that gives it a thick, sticky consistency.

What are the advantages of lithosphere?

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.

What are examples of lithosphere?

Lithosphere is defined as the rock and crust surface that covers the Earth. An example of lithosphere is the Rocky Mountain range in western North America. The outer part of the earth, consisting of the crust and upper mantle, about 100 kilometers (62 miles) thick. The solid, rocky part of the earth; earth’s crust.

How is lithosphere useful to us?

What is the function of lithosphere?

Functions of lithosphere (its upper layer) as a global system including anthropogenic and natural processes taking place within it are the principal life- supporting functions determining development and existence of the modern society and the plant and animal life as a whole.

How thick is the lithosphere?

about 100 km thick
The lithosphere is about 100 km thick, although its thickness is age dependent (older lithosphere is thicker). The lithosphere below the crust is brittle enough at some locations to produce earthquakes by faulting, such as within a subducted oceanic plate.

What are 5 facts about lithosphere?

The continental lithosphere is comprised of igneous rock called felsic rock. This rock is rich in the elements required to form quartz and feldspar. The oceanic lithosphere is comprised of mafic crust and ultramafic mantle. The mafic crust is made up of silicate mineral that is rich in iron and magnesium.

What are the disadvantages of lithosphere?

Disadvantages of lithosphere are…

• Flooding of dam areas.
• Contamination of fish.
• Very expensive to set up.
• Still in the prototype stage.
• Requires constant wind.

What are 3 examples of lithosphere?

An example of lithosphere is the Rocky Mountain range in western North America. The rocky lithosphere includes part of the upper mantle and crust. All terrestrial planets have lithospheres. The lithospheres of Mercury, Venus, and Mars are much thicker and more rigid than Earth’s.

What is the importance of lithosphere to human?

The lithosphere is very important because it is a large reservoir of resources , which are so useful to man. The majority of the material objects which man requires are supplied by lithosphere.

What are some facts about the lithosphere?

The lithosphere is the solid outer section of Earth which includes Earth’s crust (the “skin” of rock on the outer layer of planet Earth), as well as the underlying cool, dense, and fairly rigid upper part of the upper mantle. The lithosphere extends from the surface of Earth to a depth of about 44-62 mi (70-100 km).

Why is the thermosphere impontant to life on Earth?

The thermosphere is very important for human life as it contributes enormously to protecting the earth, as well as enabling space exploration and modern forms of communication. It recycles water, absorbs the sun’s energy and creates a moderate temperature. This helps protect the earth from the extremely cold temperatures that come from space.

How do you describe the lithosphere?

Summary The lithosphere is the brittle crust and uppermost mantle. The asthenosphere is a solid but it can flow, like toothpaste. The lithosphere rests on the asthenosphere.
