The Rock Cycle PB15

The definition of a rock is a naturally occuring, a solid mixture of organic matter and one more minerals, physical and chemical processes act on rocks to create and destory it.

The 3 types of rocks are igneous, sedimentary, and metamorphic.

The igneous rock is formed under the surface and hot magma cools quickly.

The sedimentary rock is formed by mineral grain eroded from rocks on earth's. Layers build on top of each other.

The metamorphic rock is ofrmed by tectonic boundaries when some rocks get forced below the surface.

Sedimentary- An example of a rock is limestone. Limestone is used in the purification of molten glass.
Igneous- An example of a rock is Basalt. Basalt is used in building blocks for construction.
Metamorphic- An example of a rock is Quartz. Quartz is used in making glass, jewlery, and electronics.

Plate Tectonics is created to the creation of rocks because plate tectonics produces lava and lava produces rocks.
