Rock Cycle
Storyboard Text
- A sedimentary rock Can change to a metamorphic rock, and to a igneus rock If it melts.
- . Sediment can consist of rocks and minerals, as well as the remains of plants and animals.
- are formed on or near the Earth's surface, in contrast to metamorphic and igneous rocks, which are formed deep within the Earth. The most important geological processes that lead to the creation of sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification.
- Igneous rocks are formed when lava from a volcano cools bellow earth’s surface
- Igneous rocks formwhen magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust.
- Metamorphic rocks form when sedimentary or igneous rocks change after being exposed to extreme heat or preassure without melting
- form when heat and pressure transform an existing rock into a new rock. Contact metamorphism occurs when hot magma transforms rock that it contacts.
- I’m a sedimentary
- Sediments are grains of rocks, minerals, or mineraloids deposited on the surface of the earth. ...As sediments are buried, the weight of overlying material exerts pressure, causing compaction of the sediments.
- sedimentary rocks are composed of the solid products of weathering (gravel, sand, silt, and clay) cemented together by the dissolved weathering products.
- Igneous rocksform when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust.
- There are 3 types of rocks: Sedimentary, Metamorphic and igneous that’s me!
- And they are sedimentary and metamorphic rocks.
