The Earth
The Earth's structure is made up of the crust, mantle, outer and inner core.
The inner core of the Earth is solid because of the extreme pressure. It contains iron and nickel and its temperature can be up to 5500°C. It is about 1300km thick.
The outer core of the Earth is liquid and is made up of molten iron and nickel. It is about 2300km thick and is around 4000°C.
The mantle is the thickest part of the earth. It is made up of molten rock and is 2900km thick. Its temperature can range from 500°C to 2000°C.
The Earth's crust is a thin layer of rock around the earth's surface. It ranges from 6 - 70km in thickness.
There are these plates called the tectonic plates that make up the Earth's crust and causing the movement of the continents.
This movement is due to the hot temperature of the core of the earth that heats up the lower part of the mantle, causing a convection current within it. This current rises to the top part of the mantle and touches the crust, causing the plates to collide, push away or slide past each other.
