Rocks can be divided into three groups based on their method of information.
Igneous rocks are formed by the cooling of igneous rock material. There are two types. There are the extrusive igneous rocks which form when lava cools above the Earth's surface, and the intrusive igneous rocks which form when magma cools below the Earth's surface.
Sedimentary rocks are formed by the solidifying of accumulated sediment. They can be clastic sedimentary rocks which are formed from sediment that has been produced by the sedimentary cycle, or non-clastic sedimentary rocks which are formed from chemical or organic deposits.

Easter Island
Easter Island is in the South Pacific, 3,700 kilometres from the coast of Chile. On the island, there are 600 large statues.
