  1. Rocks are not what they seem. They are constantly changing. Changes can take millions of years or happen very quickly. Find out what happens step by stepby repeatedly clicking the mouse or pressing the enter key ………

  2. Magma(molten rock) sediment is compacted (squashed) and particles get cemented shells limestone mud mudstone Any rock can be weathered or eroded to mud or sand sand sandstone heat and pressure fast cooling Igneous rock marble heat and pressure slate slow cooling Sediment Sedimentary rock weathering and erosion Metamorphic rock basalt small crystals granite large crystals cooling and crystallisation (solidification) very high temperatures causing melting very hot!

  3. Some changes are rapid eg landslides and volcanic eruptions … … but much of the cycle takes millions and millions of years! Click here to run the Rock Cycle again automatically!
