Across
- 1. The processes that break up and corrode solid rock, eventually transforming it into sediment.
- 4. A vertical sequence of distinct zones of soil.
- 5. The layer of regolith in which water dissolves ions and picks up very fine clay; these materials are then carried downward by infiltrating water.
- 9. The B-horizon, or zone of accumulation, in a soil; it underlies the topsoil.
- 10. The layer of regolith in which new minerals precipitate out of water passing through, thus leaving behind a load of fine clay
- 12. The removal of soil by wind and runoff.
- 13. An accumulation of loose mineral grains, such as boulders, pebbles, sand, silt, or mud, that are not cemented together.
- 14. Process in which chemicals destroy and alter minerals.
Down
- 2. The grinding away and removal of the Earth’s surface materials by moving water, air, or ice
- 3. Distinct zones within a soil, distinguished from each other by factors such as chemical composition and organic content.
- 6. The top soil horizons, which are typically dark and nutrient-rich.
- 7. The process in which intact rock breaks into smaller grains or chunks.
- 8. Sediment that has undergone changes at the surface of the Earth, including reaction with rainwater and the addition of organic material.
- 11. A given type of soil in a common soil classification scheme; for example, an aridisol is a soil order formed in very dry climates.
- 15. A fragment or grain produced by the physical or chemical weathering of a rock.
