Rocks and Minerals
Rocks can form in three ways. Igneous rock is cooled melted rock. Sedimentary rock is pressed layers of sediment. Metamorphic rock is changed by heat and pressure. You can observe if a rock is hard or soft, layered, crystalline or grainy.
1.Sort the rock clues
Write one: Igneous, Sedimentary, Metamorphic.
- Melted rock that cooled and became solid
- A rock changed by heat and pressure
- Marble changed from limestone by heat and pressure
- Sandstone with visible layers
- Pressed layers of sediment
- A rock from cooled lava
2.Name the type
1. Sandstone with visible layers is which type?
2. Marble that was limestone, then changed by heat and pressure, is which type?
