The Rock Cycle

This bubble is all about the rock cycle and how each different rock can change into another type of rock. If a metamorphic rock continues to heat up, it can melt into magma. When the molten cools, it can form into an igneous rock. A metamorphic rock can also turn into a sedimentary rock by erosion breaking it, then all the particles stacking together in layers, forming a sedimentary rock.An igneous rock can also be eroded and can be turned into a sedimentary rock. A sedimentary rock also can be melted and turn into magma, then when it cools, it is an igneous rock. An igneous rock can melt into magma, then cool turning into an igneous rock again. A sedimentary rock can be eroded and build up again and turn into a sedimentary rock again. Metamorphic rocks can also turn into a metamorphic rock again by heat and pressure.

Igneous Rocks

This bubble is all about igneous rocks! Igneous rocks are made when magma cools inside or outside Earth's surface. They are the most common type of rock found in Earth's surface. Some types of igneous rocks are obsidian, granite, pumice, gabbro, and many more. Gabbro often contains some amounts of chromium, silver, and gold. 95% of Earth's crust is made up of igneous rocks.

Sedimentary Rocks

This bubble is all about sedimentary rocks! Sedimentary rocks are rocks made of small bits of sediment, and are made by bits of sediment getting stacked up and pressed together by their own pressure. These pieces of sediment gets carried aroung by wind, running water, gravity, glaciers, and waves. Each sedimentary rock has layers of sediment because of the sediment collecting in layers and turnning into a sedimentary rock. Some types of sedimentary rock are breccia,sandstone, limestone, flint, and much more rocks. Sedimentary rocks can be formed in lakes, seas, rivers, and deserts. Sedimentary rocks make up much of southern England. Sediment can include minerals, such as small pieces of plants and other organic matter. Sedimentary rocks can form layers that are called strata, which can often be seen in an exposed cliff. Sedimentary rocks cover up almost 75% of Earth's surface.

Metamorphic Rocks

This bubble is all about metamorphic rocks! Metamorphic rocks are formed by heat and pressure. When a rock gets pushed nears Earth's surface, it gets lots of pressure from all the ground above it. Then, it gets lots of heat from the Earth's core, and when the rock gets pushed back up to the surface and cools down, it's a metamorphic rock. Some types of metamorphic rocks are gneiss, schist, marble, phyllite, and many other types.Marble originates from limestone and schist can originate from slate, which is another type of metamorphic rock. The word metamorphic means "changed form". The Taj Mahal in India is entirely made up of different types of marble, which is a type of metamorphic rock.

Here on this presentation, you are able to learn about the rock cycle, and the three types of rocks. On this website, there are pages about each type of rock, igneous, metamorphic, and sedimentary rock, how they are made, and fun facts about each one.
