They are the solid mineral materials forming part of the surface of Earth and are broadly categorized as Igneous, Sedimentary and Metamorphic Rocks. Rocks make up mountains, hills, valleys, plains and they also form river and ocean beds. Rocks play an important role in our life as many minera...
This quiz will test your knowledge about the three main types of rocks: igneous, sedimentary, and metamorphic. Each question in our quiz is designed to help you learn interesting facts about how these rocks are formed and where you can find them. For example, did you know some rocks come ...
What are the three major types of rocks? Learn about igneous, sedimentary, and metamorphic rocks, how these rocks are formed, and what...
Types of Rocks Geologists classify rocks into three main groups: igneous rock, sedimentary rock, and metamorphic rock. Metamorphic Rock is formed by heat and pressure from other rocks. Depending on how the rock formed, rocks can be igneous, sedimentary, or metamorphic. Igneous Rock Igneous rock,...

Igneous rocks, formed at relatively high temperatures of approximately 650掳C to 1200掳C, and sediments, deposited at the earth's surface, represent extreme ends of the temperature range realized in the processes of rock formation. In the course of later geological events, such rocks may become...
Explore the world of geology and the types of rocks found on Earth, which are classified by how they form. Learn about the three types of rocks: igneous rocks, sedimentary rocks, and metamorphic rocks. Types of Rocks There are three types of rock on Earth: igneous, sedimentary, and metam...
Metamorphic rocks are made out of the first two types of rocks, deep within the earth’s crust. We call these metamorphic or ‘changed’ rocks. Sometimes sedimentary and igneous rocks are subjected to pressures and heat so intense that they are completely changed. They become metamorphic rocks!
Metamorphic rocks are the result of pressure and heat applied to igneous or sedimentary rocks. The appearance of these rocks is transformed along with the structure; for example, metamorphic sedimentary rocks retain the layers, but the layers are bent and compressed. Some examples of metamorphic roc...
