Types Of Rocks Chart - There is no agreed number of specific types of rock. Use this chart and the accompanying cards to learn the three types of rocks: Rocks on earth are classified according to the way they were formed. Formed in fault zones, it is characterized by a layered or banded appearance due to extreme deformation. Updated on june 02, 2019. Web in geology, pictures of rocks can be used to help you best determine which of the three major types a particular rock belongs to: Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water. Igneous rocks form when molten rock (magma or lava) cools and solidifies. If they erupt from volcanoes onto the surface as lava, they are called extrusive rocks. Web the three main types, or classes, of rock are sedimentary, metamorphic, and igneous and the differences among them have to do with how they are formed.
