What Makes Up the Earth

Jessica Palomares, Contributor

The Earth has four layers that makeup Earth. The first layer is called the Crust, and it’s the thinnest layer. The second layer is the Mantle, and it’s the thickest layer. The third layer is called the Outer Core, and the Outer Core is made up of composed iron and liquid. The last layer is called the Inner Core, and it’s the hottest and deepest part of the Earth.

The Earth is mostly made of rock and metal. The Core is made of two layers the inner core and the outer core. The lighter ones, for example, water and air stayed on top of the crust. The innermost part of the core is a bit solid lead ball, which is about 1,500 miles (2,400 kilometers) thick, because of that pressure it cant melt. It is between 9,000 and 13,000 degrees Fahrenheit, and it’s as hot as the Sun’s surface.

The second layer of the core is made of liquid iron and nickel and is about 1,400 miles (2,300 kilometers) thick, and it is 7,200 to 9,000 degrees Fahrenheit this is because of the flow of metals in the inner core. The magnetic field extends beyond the Earth far into space and forms a barrier that helps protect the Earth from the Sun’s destructive solar winds.
