Metamorphic Rock

The metamorphic rock is one of the 3 main types of rock and it is part of the rock cycle. Metamorphic rock forms down beneath Earth's surface when it's really hot and things are pressing on the rock really hard the pressure is applied to either igneous rock or sedimentary rock. Metamorphic rocks are most commonly found on or near mountain ranges. Heat and pressure from colliding tectonic plates. The types of metamorphic rock are genesis, phylactery, schist, and slate. Those rocks look beaten up because they were exposed to heat and lots of pressure. This type of metamorphic rock does not have a beaten up appearance because it is made of mostly calcium carbonate and the rock is marble.

Fun facts

Sedimentary

A rock is made up of many different minerals. Each rock does not have identical structures. Believe it or not some rocks come through space called meteorites, some meteorites are made of different minerals than an Earth rock. But usually they are made of iron. Sometimes when a meteorite hits Mars, parts of rock go into space . Some of those rocks get trapped in Earth's gravitational field and then finally come down to Earth's surface.

Sedimentary rock is part of the rock cycle and is one of the 3 main types of rocks on Earth. The 3 main types of rock include igneous rock, sedimentary rock, and metamorphic rock. Sedimentary rock forms by deposition of the remains of broken rocks and from rain wearing away the rock. Turning it into small bits of rocks. As it piles, pressure builds up, making them stuck together in layers and finally turning it into a solid rock.This process is known as lithification. Sedimentary rock also forms by erosion and where the wind carries sediment it then lands, and gets mixed together forming sedimentary rock. The types of sedimentary rock are limestone, sandstone, chalk, clay, and shale.

Igneous rock

Igneous Rock

The rock cycle is a long cycle that has been going on since the beginning of the Earth and it is still going on today. In this web page I will be talking about the 3 types of rocks and how they form.

When Earth was created there was no signs of life, but rocks were there and magma. Which created the very first type of rock, igneous rock. The way the Earth creates igneous rock is the cooling and hardening of magma. Some examples of igneous rock are granite, obsidian, and basalt. Granite is a types of igneous intrusive rock that forms beneath Earth's surface the magma tries to look for a crevice, and when it does it fills and hardens.

Obsidian and basalt are examples of extrusive igneous rock which form by when magma rises from inside earth the Earth and then hardens on the surface or it when a volcano erupts or explodes from the pressure building up. The rock then hardens on the surface. The Earth's plates are igneous rock and the type of igneous rock is granite. The plates are constant changing because of faults, earthquakes, and volcanoes. Also, igneous rocks create metals, minerals, and building materials to help build buildings.
