Here on The forces of nature, you will find reliable information on the different types of rocks. On this website you will find videos and pictures of rock adventures and the different types.
Sedimentary rocks are formed by the accumulation of different sediments.
Chemical sedimentary rocks: Chemical sedimentary rocks such as rock salt, iron ore, chert, and flint form when materials that have dissolved precipitate from a solution.
Metamorphic rocks have been changed/ modified by chemical processes, heat, and lastly pressure. this happens when the rock is buried below the earths surface. There are two different types of metamorphic rocks.
Foliated metamorphic rocks: The rocks gneiss, phyllite, schist, and slate have a layered appearance.
Non foliated metamorphic rocks: hornfels, marble, quartzite, and novaculite do not have a layered appearance.
Where are the rocks located?
Here's a color coordinated map to show you where you can find these rocks. The pink area is metamorphic which is located on the north side. igneous is located on the west side. And lastly sedimentary is located in the Midwest/east section of the map.
What is a rock cycle?
A rock cycle, is cycle of processes undergone by rocks in the earth's crust. it is also a model that shows the formation, and breakdown of a rock as a result of sedimentary, igneous, and metamorphic processes.
Igneous rocks are formed by the cooling and solidifying of materials. Igneous rocks can form beneath the Earth's surface, or at its surface as lava!
