A Trip Around The World- Rock Cycle and Types of Rocks

The Rock Cycle

The rock cycle is a cycle in which rocks go through. Rocks have been going through this cycle for billions of years and will continue to until the world ends. :( In the rock cycle, different types of rocks can be changed into another type of rock by heat, pressure, weathering, erosion, melting, cooling, or compaction.
The picture on the right is a volcano erupting. Igneous rock could soon be formed.
