Facts about Earth

Hello everyone here are some more facts about Earth.

The Earth’s inner core is so hot it could melt metal, it remains solid because it is surrounded by such immense pressure.

The Earth is made up of different layers, which formed when the planet was young and extremely hot. These layers are all held in place by the enormous force of gravity, acting upon the planets inner core and incredibly hot ball of iron and nickel.

Some of the layers are partly molten which means that they contain extremely hot liquid and are covered by an outer layer of solid rock and called the crust.

The rock that makes up the surface of the Earth is constantly changing as more and more layers are added. Its composition can be divided into three different types of rock.

Estimates of the temperature of the Earth’s inner core vary but scientists believe it is most likely between 5,000 – 7,000 degrees Celsius or 9,000-13,000’s degrees Fahrenheit.
