Question

What are the three internal layers of the earth?

Answer 1

Hint: Earth is divided into four layers. The majority of geologists conclude that as the Earth cooled, the heavier and denser material sunk to the middle, while the lighter material rose to the top. The lightest materials, such as rocks and granites, make up the outermost layer, while nickel and iron make up the innermost layer.

Complete answer:
The inner core, the outer core, mantle and crust are the four layers of earth.

Inner core: It is the Earth's core and the hottest layer. With a temperature of up to 5,500oC, the inner core is solid and made of iron and nickel. The inner core resembles the Earth's engine room because of its tremendous heat capacity.

Outer core: The Earth's outer core resembles a very hot metal ball with a temperature ranging from 4000 oF to 90000 oF. The metals inside are all liquid due to the extreme heat. The outer core is about 1800 miles under the crust and is about 1400 miles thick. It is made up of metals like iron and nickel. The inner core is encircled by the outer core.

Mantel: The Earth's mantle is the largest part of the planet. It has a thickness of around 2,900 kilometres. Magma, a semi-molten rock, makes up the majority of the mantle. The rock in the upper part of the mantle is heavy, but it becomes softer and melts as it descends.

Crust: The crust is the outermost layer of the Earth's surface, where we work. The thickness ranges from 0 to 60 kilometres. It's a solid rock layer that comes in two varieties: The continental crust protects the surface, while the oceanic crust protects the water. The crust has been researched and known the most. The mantle is cooler and can flow.

Note:
-The Earth is made up of three layers, similar to the layers of an onion. The crust, mantle, and heart are the three layers.
-Some of these layers contain many more layers, and they are constantly shifting.
-The planet Earth is made up of several distinct layers, each with its structure. With a thickness of 30 kilometres, the top layer, also known as the crust, is the thinnest layer of the Earth (18.6 miles).
-The upper mantle, lower mantle, outer core, and inner core are the four distinct layers found underneath the crust.
-The Earth's inner core has a variety of unusual properties.
