The three main types are igneous, sedimentary, and metamorphic rocks..
What can rocks tell us?

Granite, Salt, Quartz, and Marble Granite and marble counter tops are made from stone. Granite forms when magma cools within the earth and never erupts from a volcano. The slower it cools, the larger the mineral grains that form. Marble is formed from limestone that is cooked by heat and pressure within the earth.
