Rock Cycle
Sedimentary Rock | Sedimentary Rocks are the types of rocks that are formed by the deposition and subsequent cementation of that material at the earth's surface and within bodies of water. |
Sandstone | Sedimentary Rock and Sandstone consisting of sand or quartz grains cemented together, typically red, yellow, or brown in color. |
Igneous Rock | Igneous Rock is formed through the cooling and solidification of magma or lava. |
Metamorphic rock | A Metamorphic rock is a result of a transformation of a pre-existing rock. The original rock is subjected to very high heat and pressure, which cause obvious physical and/or chemical changes. |
How Sedimentary rock is formed | Sedimentary rocks are formed when sediment is deposited out of air, ice, wind, gravity, or water flows carrying the particles in suspension. This sediment is often formed when weathering and erosion break down a rock into loose material in a source area. |
How Metamorphic rock is formed | Metamorphic rocks are created by the physical or chemical alteration by heat and pressure of an existing igneous or sedimentary material into a denser form. |
How Igneous rock is formed | Igneous rock is formed through the cooling and solidification of magma or lava. Igneous rock may form with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks. |
How Sandstone is formed | Sandstone is a clasic sedimentary rock composed mainly of sand-sized minerals or rock grains. Most sandstone is composed of quartz and/or feldspar because these are the most common minerals in the Earth's crust. |
The rock cycle | The rock cycle is an idealized cycle of processes undergone by rocks in the earth's crust, involving igneous intrusion, uplift, erosion, transportation, deposition as sedimentary rock, metamorphism, remelting, and further igneous intrusion. |
Limestone | Limestone is formed in two ways. It can be formed with the help of living organisms and by evaporation. Ocean-dwelling organisms such as oysters, clams, mussels and coral use calcium carbonate. |
What is Limestone | Limestone is a hard sedimentary rock, composed mainly of calcium carbonate or dolomite, used as building material and in the making of cement. |
Why do we use the rock cycle? | The rock cycle is a model that describes the formation, breakdown, and reformation of a rock as a result of sedimentary, igneous, and metamorphic processes. |
