Inside The Earth
There are different parts to the Earth.
There is a thin, rocky crust, a solid middle called the mantle and a center called the core. The outer part of the core is liquid but the inner core is made of solid metal.

Around the center of the Earth Flow a hot, liquid layer of iron and nickel.
This lager is the outer core and is about 2200 kilometers thick. As the Earth spins, the metal ball and liquid layer move at different speeds.

At the center of the Earth is a huge metal ball called the inner core. It is
2500 kilometers wide and is made mainly from iron, with some nickel.
The ball has an incredible temperature of 6000°C — hot enough to make the metals melt.
They stay solid because other parts of the Earth push down heavily on them.

( If the Earth could be cut open, this is what you would see inside, It has layers inside it like an onion.)
The largest part o-f Earth is a layer called the mantle, which is 2-900 kilometers thick.
It lies between the core and the crust. Near the crust, the mantle is made of slow-moving rock. When you squeeze an open tube of toothpaste, the toothpaste moves a little like the rocks in the upper mantle.

The Earth’s surface is covered by crust.
Land is made of continental crust between 20 and 70 kilometers thick. Most of this is made from a rock called granite. The ocean bed is made of oceanic crust about eight kilometers thick. It is made mainly from a rock called basalt.

The crust is divided into huge slabs of rock called plates.
Most plates have land and seas on top of them but some, like the Pacific Plate, are mostly covered by water. The large areas of land on the plates are called continents. There are seven continents — Africa, Asia, Europe, North America, South America, Oceania and Antarctica.

Very, very slowly, the continents are moving.
Slow-flowing mantle under the crust moves the plates across the Earth’s surface. As the plates move, so do the continents. In some places, the plates push into each other. In others, they move apart. North America k moving three centimeters away from Europe every year!
