Question

what are the three internal layers of the earth​

Answer 1

Explanation:

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.

The dense, hot inner core (yellow), the molten outer core (orange), the mantle (red), and the thin crust (brown), which supports all life in the known universe. Earth's interior is generally divided into three major layers: the crust, the mantle, and the core.

Answer 2

Answer:

The Earth is made up of several concentric layers with one inside another just like the onion. The three layers of the earth are the crust, the mantle, and the core. The uppermost layer or crust is the thinnest of all layers. It is 35 km on the continental masses and only 5 km on the ocean floors. Just beneath the crust is the mantle which extends up to a depth of 2900 km. The innermost layer is the core with a radius of about 3500 km. It is made up of nickel and iron and is therefore called a knife. The central core has very high temperature and pressure. The crust forms only 0.5 percent of the volume of the earth, 16 percent consists of the mantle and 83 percent makes the core.
