Rock cycle- There is three different kind of rock such as sedimentary rock which formed when many pieces of rock combine together and by different process such as weathering-rocks and other material break down on earth surface, erosion-weather material get moved place to place, sediment get together with process called compaction, then it glued together by cementation. Finally, it becomes sedimentary rock.  Metamorphic rock that form when magma melted from inside of the earth by heat and pressure. And igneous rock formed when minerals get melt that are cool and harden and with process called solidification in which liquid turn into solid.

Rocks

Magma: melted rock come from inside of the earth.

Lava: come from outside the earth.

Sediments: broken pieces of rock.

Compaction: when rocks combine together.

Cementation: glued together.

Sedimentary rock: formed when many pieces of rock get together.

Igneous rock: formed when minerals get melt that are cool and harden.

Metamorphic rock: formed underground by heat and pressure.

Erosion:material get moved place to place.

Weathering: rock and material break down on earth surface.

 sedimentary rock formed when many pieces of rocks and minerals combine together.
