- 1. Consists of all the organisms and the physical environment with which they interact.
- 4. An ecoregion of the temperate broadleaf and mixed forests biome.
- 8. A gradual process that occurs when the impact of water or wind detaches and removes soil particles, causing the soil to deteriorate.
- 9. The branch of soil science that deals with the chemical composition, chemical properties, and chemical reactions of soils.
- 13. Large three-needled pine of southeastern United States having very long needles and gnarled twisted limbs.
- 16. The weather conditions prevailing in an area in general or over a long period.
- 19. The amount of water (in mm of water depth) present in a depth of one meter of soil.
- 20. A soil consisting of a friable mixture of varying proportions of clay, silt, and sand.
- 21. A form of treefall in which the root plate of a tree is torn from the soil, disrupting and mixing it and leaving a pit-mound.
- 22. A means of defining Earth's landforms into distinct regions, based upon the classic three-tiered approach by Nevin M. Fenneman in 1916, that separates landforms into physiographic divisions, physiographic provinces, and physiographic sections.
- 23. The elevation of a geographic location is its height above or below a fixed reference point.

- 6. Low-lying land along a watercourse.
- 7. The imaginary line where two or more rivers or parts of a river plunge, or fall, at the same elevation.
- 9. Geographical and climate zones to the north and south of the tropics. Geographically part of the temperate zones of both hemispheres, they cover the middle latitudes from 23°26′10.6″ to approximately 35° north and south.
- 10. A coastal plain is flat, low-lying land adjacent to a sea coast.
- 11. In geology and physical geography, a plateau, also called a high plain or a tableland, is an area of a highland consisting of flat terrain that is raised sharply above the surrounding area on at least one side.
- 12. A measure of the degree to which the climate of a region is influenced by a maritime airflow from the oceans.
- 14. The arrangement of the natural and artificial physical features of an area.
- 15. A bottomland, deciduous or deciduous-conifer forest community occupying low-lying areas adjacent to streams and rivers of third order or greater, and subject to periodic over-the-bank flooding and cycles of erosion and deposition.
- 17. Are usually deciduous, meaning they lose their leaves in the autumn.
- 18. A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean.
