1. Igneous Rock
- How each type is formed: Formed from the cooling and solidification of magma or lava.
- Two describing words: Crystalline, Volcanic
- Identify 1 type and draw a picture of it: Basalt (picture would show dark, fine-grained rock)
2. Sedimentary Rock
- How each type is formed: Formed from the accumulation and lithification of sediments (like sand, silt, or organic material).
- Two describing words: Layered, Fossiliferous
- Identify 1 type and draw a picture of it: Sandstone (picture would show visible sand grains and layers)
3. Metamorphic Rock
- How each type is formed: Formed when existing rocks are changed by heat, pressure, or chemically active fluids.
- Two describing words: Foliated, Recrystallized
- Identify 1 type and draw a picture of it: Gneiss (picture would show banded or striped appearance)
Parent Tip: Review the logic above to help your child master the concept of three types of rocks worksheet.
