Question

Describe the following mechanical layers in the earth.

1.)lithosphere
2.)asthenosphere
3.)mantle
4.)outer core
5.)inner core

Answer 1

1.)lithosphere : The lithosphere is the solid, outer part of the Earth, including the brittle upper portion of the mantle and the crust

2.)asthenosphere : Asthenosphere, the zone of Earth’s mantle lying beneath the lithosphere and believed to be much hotter and more fluid than the lithosphere. The asthenosphere extends from about 100 km (60 miles) to about 700 km (450 miles) below Earth’s surface.

3.)mantle : The mantle is the mostly-solid bulk of Earth's interior. The mantle lies between Earth's dense, super-heated core and its thin outer layer, the crust. The mantle is about 2,900 kilometers (1,802 miles) thick and makes up a whopping 84% of Earth's total volume.

4.)outer core : The outer core, about 2,200 kilometers (1,367 miles) thick, is mostly composed of liquid iron and nickel. The NiFe alloy of the outer core is very hot, between 4,500° and 5,500° Celsius (8,132° and 9,932° Fahrenheit).

5.)inner core: The inner core is a hot, dense ball of (mostly) iron. It has a radius of about 1,220 kilometers (758 miles). Temperature in the inner core is about 5,200° Celsius (9,392° Fahrenheit). The pressure is nearly 3.6 million atmosphere (atm).

Answer 2

Step-by-step explanation:

1.the rigid outer part of the earth, consisting of the crust and upper mantle.

2.the upper layer of the earth's mantle, below the lithosphere, in which there is relatively low resistance to plastic flow and convection is thought to occur.

3.the mostly-solid bulk of Earth's interior.

4.the third layer of the Earth. It is the only liquid layer,

5.a hot, dense ball of (mostly) iron.
