## Transcript

**[0:00]:** Rocks are slowly but constantly changing in something known as the rock cycle. The rock cycle begins with magma or hot melted rock deep beneath the Earth's surface. This magma becomes crystallized becoming igneous rock.

**[0:19]:** These rocks begin to erode or break down into small pieces because of wind, water, or other forces. The small fragments of rock are carried away as sediment when water passes over them and are deposited in layers which eventually become sedimentary rocks.

**[0:40]:** Then some sedimentary rocks are pushed below the surface due to tectonic activity where they are exposed to heat and pressure transforming them into metamorphic rocks. If the rocks are buried even deeper they may melt and form magma starting the cycle all over again.

**[1:01]:** Of course sedimentary and metamorphic rocks can be eroded into sediment and igneous rock can become metamorphic rock or lava. But one way or another rocks all over the world keep changing from one form to the next.
