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,...

What are Rocks? 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 li...

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!
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...
There are two basic types of metamorphic rocks. Foliated metamorphic rocks have a layered or banded appearance that is produced by exposure to heat and directed pressure. Examples of foliated rocks include: gneiss, phyllite, schist, and slate Non-foliated metamorphic rocks do not have a layere...
Types of Rocks There are three main types of rocks: Igneous - formed when molten rock cools. Sedimentary – formed by the “cementing together” of small grains of sediment. Metamorphic – rocks changed by the effect of heat and pressure. Igneous Rocks These are rocks formed by the cooling ...
