Rock cycle
Storyboard Szöveg
- The Volcano erupts breaking out a bunch of small rocks called indigenous. This rock is made by when magma cools and crystallizes on or beneath the earths surface. The type of crystals in the rock are fine grain (small crystals). The texture is crystal/particle size, and cools very quickly. It is extrusive.
- When it shoots out and hits the ground, and bunch of different rocks or all these different stuff combined with it for a sedimentary rock. They form when the tiny pieces that brake off the indigenous rock cement together. combined with coarse grain or fine grain. Could also be a metamorphic and keep changing back and fourth defending on the formation. The heat and pressure force it to sink back into the ground.
- Why rocks rocks move from place to place is caused by the earths forces. Like wind, water, volcanic eruptions, and plate movement. The plate movment puts great heat and presure on the rocks. Thats the main reason why the rocks change. The other type of rock we havnt tallked about much is the metamorphic rock. These are formed when rocks are encountered with really high heat, presure, and hot minerals. This all happenes deep within the earth where the plates meet.
