Across
  1. 3. Boundaries Places where land plates slide past each other, causing earthquakes along fault lines
  2. 5. Tectonics A scientific idea explaining how Earth's big pieces of land (plates) move and interact
  3. 7. A kind of hard rock with big crystals that forms underground
  4. 8. Intrusive Rock Rocks formed when magma cools slowly beneath the Earth's surface, creating rocks like granite and diorite with a rough texture
  5. 9. Rock Rocks made by piling up and sticking together tiny bits of rocks and dirt over time
  6. 12. Rock Rocks that change because they are squeezed and heated a lot, becoming rocks like marble and schist
  7. 13. System How the tiny particles (atoms) in a crystal are arranged, giving the mineral a specific shape
  8. 15. Boundaries Places where land plates move away from each other, often creating new land like mid-ocean ridges
  9. 16. When a mineral breaks along smooth, even planes or surfaces
  10. 17. A rock with different bands of minerals, created under intense heat and pressure
Down
  1. 1. When a mineral breaks in a way that isn't smooth, often creating rough or jagged surfaces
  2. 2. A rock formed from lava cooling quickly on the surface, found in volcanic areas
  3. 4. Erosion Water moving and carrying away rocks and soil, shaping features like river valleys and coastlines
  4. 6. Weathering Rocks breaking into smaller pieces due to things like ice, wind, or plant roots without changing what they're made of
  5. 7. Erosion Big moving ice shaping the land by carving valleys and creating features like fjords
  6. 8. Extrusive Rock Rocks formed when hot lava cools down quickly on the Earth's surface, making rocks like pumice and basalt with a smooth texture
  7. 10. Weathering Rocks changing because of chemicals, like when they react with water or air, slowly dissolving or rusting
  8. 11. How tough a mineral or rock is — it's about how easily it can be scratched
  9. 14. A type of rock made from the remains of sea creatures, often used in building
  10. 16. Boundaries Places where land plates move toward each other, causing subduction, mountain building, and other big changes
