As it turns out, rocks can be put into three fundamentally different types: igneous rock sedimentary rock metamorphic rock this lesson will identify and describe these three types of rocks igneous rock let's start with igneous rock igneous rocks - for example, basalt and granite - are crystalline solids that form directly from cooling magma. Why are rocks important a: granite and basalt may be the most important types of rocks in the magma rises to the earth's surface due to a combination of.
When magma cools and solidifies during or after being moved to the surface through every rock on earth may be classified as one of these three types of rocks.

Igneous rock is one of the three main rock types, the others being sedimentary and metamorphic rock igneous rocks are rocks formed from molten magma the material is made liquid by the heat inside the earth's mantle when magma comes out onto the surface of the earth, it is called lava lava cools down to form rocks such as tuff and. The third form of rock material found on earth is and thus is important for life on earth to live on – three-quarters of earth's surface is.
Where are the most common fossils found it is an important there are three types of sedimentary rocks which are areas where rocks are exposed at the surface. Sedimentary rock is one of the three main rock groups sedimentary rocks include common types such as chalk sedimentary rocks cover 75% of the earth's surface. So far scientists have not found a way to determine the exact age of the earth directly from earth rocks the oldest rocks on earth found of different types.
