What are some of the differences and similarities between the mantle crust and the core?

Answer 1

Crust- The crust is the thinnest layer of the Earth and is from 0-50 km deep. The crust is not one whole rather it’s separated into different pieces called the plates. The earth’s crust is also the lightest layer, it’s rocky and rigid.

Mantle- The mantle of the Earth is the largest and the layer that takes up most of the space-2900 km deep. The mantle is mostly made up of magma and molten rocks because of the heat given off by the core.

Core- The core is the hottest, second biggest and inner most layer of the earth. It mainly consists of solid iron and nickel. The heat in the core is what causes the mantle to be in fluid form. The core is really hot heating up from 3500 C to more than 6000 C

Compare-

The similarities of the three types of layers are-

1. The three layers help to support the structure of the Earth.

2. The mantle and the core are really hot and the two biggest layers.

3. Both the Mantle and crust are solid.

Contrast-

The difference is that the crust of the earth is made out of soil and rocks while the mantle consists of lava and molten rocks, finally the core is made up of solid iron and nickel. All the layers are made up of different natural materials.

Answer 2

They are all planets, they orbit the sun, they are all in our solar system, and people have not visited any of them, and they have an core, outer core mantle lithosphere and crust, orbits around stars, made of matter and more

Answer 3

Similarities- The Mantle and the core are both solid and molten. The upper mantle is made of solid rock and the inner core is solid because of extreme pressure. The lower mantle and the outer core are both molten rock.

Differences- Temperatures

-mantle= upper mantle is 1000o C and the lower mantle is 2500

-core= outer core is 4000o C and the inner core is 5000-5700

Answer 4

the outer core is a molten metal that surrounds the inner core. In spite of enormous pressure, the outer core behaves like a thick liquid. The inner core is a dense ball ofsolid metal. In the inner core,extreme pressire squeezes the atoms of iron and nickel so much that they cannot spread out and become liquid.

Answer 5

They both have hot molten core in constant convection motion within.

Answer 6

Both are made of nickel-iron alloy and are at very high temperature and pressure.

i dont not know rate me 5 stars
