What is an example of the mantle?

The definition of a mantle is a shawl or a cloak. An example of a mantle is a fancy shawl worn over a cocktail dress.

What is the biblical definition of mantle?

The mantle was originally a cape worn simply to ward off the cold. The mantle was first mentioned in the Old Testament, as a garment worn by several prophets including Elijah and Elisha.

What is the other name for Mantle?

Answer. ÔŁąThe outer layer of the earth, where we reside, is called the crust. Below the crust is the uppermantle, with the upper-most portion referred to as the asthenosphere. The upper mantle is liquid rock, and very hot.

What are 3 characteristics of the mantle?

It is mostly solid rock, but less viscous at tectonic plate boundaries and mantle plumes. Mantle rocks there are soft and able to move plastically (over the course of millions of years) at great depth and pressure. The transfer of heat and material in the mantle helps determine the landscape of Earth.

What causes a mantle plume to erupt?

Plumes are postulated to rise as the base of the mantle becomes hotter and more buoyant. Plumes are postulated to rise through the mantle and begin to partially melt on reaching shallow depths in the asthenosphere by decompression melting. This melt rises to the surface and erupts to form “hot spots”.

Is the mantle liquid?

The mantle, which makes up about 84% of Earth’s volume, is predominantly solid, but behaves as a very viscous fluid in geological time.

What is the role of the mantle?

The Earth’s mantle plays an important role in the evolution of the crust and provides the thermal and mechanical driving forces for plate tectonics. The mantle is also the graveyard for descending lithospheric slabs, and the fate of these slabs in the mantle is a subject of ongoing discussion and controversy.

What is the thickness of the mantle?

Below the crust is the mantle, a dense, hot layer of semi-solid rock approximately 2,900 km thick.

What is Mantle answer?

A mantle is a layer inside a planetary body bounded below by a core and above by a crust. Mantles are made of rock or ices, and are generally the largest and most massive layer of the planetary body. All terrestrial planets (including Earth), a number of asteroids, and some planetary moons have mantles.

What is the thinnest layer on Earth?

* 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.

Why are mantle plumes important?

Mantle plumes can be emitted from the core- mantle boundary region to reach the Earth’s crust. Because of the lateral displacement of the tectonic plates at the surface, the mantle plumes can create a series of aligned hot-spot volcanoes.

What name is given to the lower part of the mantle?

The lower mantle, historically also known as the mesosphere, represents approximately 56% of Earth’s total volume, and is the region from 660 to 2900 km below Earth’s surface; between the transition zone and the outer core.
