Explanation:

1. Sedimentary rock formation starts with weathering of pre - existing rocks, then erosion transports the weathered material, followed by deposition, compaction, and cementation.
2. Rock formed from cooling lava at the Earth's surface is extrusive igneous rock.
3. When granite undergoes high - temperature and high - pressure conditions and minerals align to give a banded appearance, it forms foliated metamorphic rock.
4. Fossils are typically found in sedimentary rocks as they form in environments where organisms can be buried and preserved.
5. Frost wedging occurs in cold regions with frequent freeze - thaw cycles, like McMurdo, Antarctica.
6. Freeze - thaw action and salt wedging both involve physical forces that break rocks due to expansion and contraction.
7. The C horizon contains bedrock.
8. The four major components of soil are mineral matter, organic matter, air, and water.
9. Grasslands generally have fertile soil suitable for farming due to the accumulation of organic matter.
10. Wind, water, and ice are all major agents of erosion.
11. Planting the same crop each season can deplete soil nutrients and does not reduce soil erosion.
