Granite, coarse- or medium-grained intrusive igneous rock that is rich in quartz and feldspar; it is the most common plutonic rock of the Earth’s crust, forming by the cooling of magma (silicate melt) at depth. Learn more about the properties and uses of granite in this article.
Scientists generally classify rocks by how they were made or formed. There are three major types of rocks: Metamorphic, Igneous, and Sedimentary. Metamorphic Rocks - Metamorphic rocks are formed by great heat and pressure. They are generally found inside the Earth's crust where there is enough heat and pressure to form the rocks.
Easier to find: Fossil fuels can be found all over the world, with many areas already identified as being rich in these resources. Very efficient: Fossil fuels can generate a lot of energy, even from just a small amount of fuel. Simpler to transport: Fossil fuels can be easily transported, e.g. using underground pipes to move oil and gas.
The Rocks Metamorphosed sedimentary rocks are the dominant rock types in the park, but some igneous rocks also occur. Sedimentary rocks form through a cycle of erosion and deposition mostly in water.
