What is Metamorphic Rock?Metamorphic rock is one of the three types of rocks. They are the result of a transformation pre-existing rock. A metamorphic rock forms form when other types of rocks are changed by heat and pressure. The heat that comes from magma may cause these types of different rocks to change. Furthermore, proving that magma may be the cause of rocks to change.

Cycle

What is an Igneous Rock?Igneous rocks were the very first rocks on Earth. The word igneous comes from the latin word, ignis meaning fire. They are formed by the cooling and sodification of molten rock material. They are deep within Earth's crust. It is divided into two groups called intrusive and extrusive igneous rocks. Instrusive rocks form crystals underneath Earth's surface and the slow process of cooling that occurs there allows large crytstals to form. Examples for instrusive igneous rocks are diorite, gabbro, granite, pegmatite and peridotite. Secondarily, exstrusive igneous rocks form when magma flows through cracks erupting onto Earth's surface. Later, they cool quickly to form small crystals. Example of exstrusive rocks are andesite, basalt, obsidian, pumice, rhyolite, scoria and tuff.

Metamorphic Rock

Magma

What is Magma? Magma is a hot liquified rock that is located deep below Earth's surface. When a valcano erupts or a deep crack occurs in the Earth, it is called lava. Magma is formed when temperature's within Earth's crust or mantle are very hot. Lava can reach temperatures of 700 to 1200 degrees Celcius (1300 to 2,200 degrees Farenheit. When lava is evetually cooled down and sodified it forms an igneous rock.

Sedimentary Rock

What is a Sedimentary Rock?Sedimentary rock is one of the three main rock groups. They are formed by the deposition of the weathered reamains of other rocks. They include common types such as chalk, limestone, sand, claya and shale. Lastly, interesting fact, did you know that sedimentary rocks cover 75% of Earth's surface.
