  1. 1. Small fragments of rock, minerals, or organic material that result from weathering and are transported by erosion.
  2. 5. The breaking down of rocks into smaller pieces (sediment) by natural forces like water, wind, ice, and temperature changes.
  3. 8. are classified into three main types: igneous, sedimentary, and metamorphic.
  4. 10. A force exerted on rocks, often deep within the Earth, that can lead to metamorphic changes.
  5. 12. A naturally occurring inorganic substance with a specific chemical composition and crystalline structure. Minerals are the building blocks of rocks.
  6. 13. The preserved remains, impressions, or traces of organisms that lived in the past. They are usually found in sedimentary rocks.
  7. 14. A sedimentary rock composed primarily of calcium carbonate, often from the remains of marine organisms such as corals and shells. It is used in construction and can also be transformed into marble under heat and pressure.
  8. 16. A factor that contributes to rock changes; high temperatures can lead to metamorphism or even melting of rock into magma.
  9. 17. A dark, fine-grained, volcanic igneous rock that is rich in iron and magnesium and low in silica. It forms from the rapid cooling of lava at the Earth's surface.
  10. 18. Cycle: The continuous process through which rocks are formed, altered, destroyed, and reformed by geological processes.
  11. 19. The hardening of molten rock into solid rock, usually as magma cools below the surface or lava cools at the Earth's surface.
  12. 22. The process by which a substance, such as a mineral, breaks down and becomes into a liquid, typically water. This is common in processes like weathering and erosion
  13. 23. Molten rock located beneath the Earth's surface, which may eventually cool to form igneous rock.
  14. 25. A metamorphic rock that forms when limestone is subjected to high pressure and temperature. It is composed primarily of recrystallized calcite or dolomite and is often used in sculpture and architecture.
  15. 26. The process where sediments are pressed together under their own weight, reducing space between particles and forming denser material.
  16. 27. The transformation of existing rock types into new rock types due to exposure to heat, pressure, or chemically active fluids, without melting.
  17. 28. Rock: Rock formed by the compaction and cementation of sediments.
Down
  1. 2. Rock: Rock that has been changed from its original form due to heat, pressure, or chemically active fluids, without melting. Examples include marble and schist.
  2. 3. Rock: Rock formed from the cooling and solidification of magma or lava.
  3. 4. The process of moving weathered rock or sediment from one place to another by agents such as water, wind, ice, or gravity.
  4. 6. example of metamorphic rock.
  5. 7. A naturally occurring solid material composed of one or more minerals.
  6. 9. When sediment is laid down or settles in a new location after being transported by erosion.
  7. 11. It forms from the slow cooling of magma deep within the Earth's crust. A type of rock.
  8. 15. The process by which magma or lava loses heat and eventually solidifies into rock.
  9. 20. The binding together of sediment particles by minerals that precipitate from water, which helps in forming sedimentary rock.
  10. 21. Rock: Rock that has been transformed by heat and pressure from a pre-existing rock without melting.
  11. 24. The process where rock is heated to a point where it turns into a liquid (magma).
