The structure of the Earth is divided into layers. These layers are both physically and chemically different. The Earth has an outer solid layer called...
electronic phones and computers. The structure of Earth changes from the inside to the outside. The center of Earth (Earth's core) is mostly iron (88.8%)...
The Earth's core is the part of Earth in the middle of our planet. It has a solid inner core and a liquid outer core. The temperature of the outer core...
The Earth's crust is the Earth's hard outer layer. It is less than 1% of Earth's volume. The crust is made up of different types of rocks: igneous, metamorphic...- Snowball Earth or Icehouse Earth refers to times when the Earth's surface was nearly or entirely frozen. The occurrence of Snowball (or Slushball) Earths is...

Impact crater (redirect from Impact structure)striking the Earth or other solid body. There is a system for recording and assessing craters. The five largest confirmed impact structures are: Vredefort...- The Earth's mantle has two layers. There is a rigid upper layer and a softer layer. It is between the Earth's crust and the Earth's outer core. Past episodes...
- Mantle (geology) (category Structure of the Earth)makes up 67% the mass of the Earth. It has a thickness of 2,900 kilometres (1,800 mi). It makes up about 84% of Earth's volume. The Earth's mantle behaves...
