With the help of a diagram, explain the interior of the earth.
Answers
Answer:
Earth can be divided into three main layers: the core, the mantle and the crust. Each of these layers can be further divided into two parts: the inner and outer core, the upper and lower mantle and the continental and oceanic crust. Both the inner and outer core are made up of mostly iron and a little bit of nickel.
Answer: The uppermost layer of the earth's surface is in solid state and is called the crust. This layer is the thinnest and is made up of hard crystalline rocks.
This layer, lies below the crust. The average thickness of this layer is 2900 km. It is made up of two layers, the upper mantle and the lower mantle. The upper • mantle extends from the Moho Discontinuity to a depth of 700 km. It is cooler and composed of solid rocks.
The outer core is about 2,200 km thick. It is mostly composed of liquid nickel (NI) and iron (Te) and therefore is also known as nife..
The inner core has a radius of about 1220 km. Though the temperature is very high at about 5,200°C, the inner core is solid due to extreme pressure,exerted on it by the other layers and the atmosphere of the earth.
