Rocks in the rock cycle

This presentation is about the rock cycle and how it works

The very first rock was acutally a liquid called magma. Magma then started to crytalize and cool down to form Igneous rock

Igneous rock can have a lot of holes in it from where the bubbles were, or very smooth like the one in this picture. Igneous then faces erosion and becomes small sediments.

Sediments are the smallest rocks in the rock cycle that can take thousands and thousands of years to form. After some cementation it moves on in the cycle to become Sedimentary rock

Sedimentary rock can have fossils or shells in it. Sedimentary rock then goes through heat and pressure and becomes the next rock in the cycle Metamorphic rock.

Metamorphic rock has lines through it that are actually layers of rocks. Metamorphic rock then melts and goes back into magma.
