GEOG 101 Lecture Notes - Lecture 10: Carbonation, Hydrolysis, Debris Flow
Document Summary
Landform: a feature of earth"s topography that can be distinguished and studied as a single unit (a single mountain, a hill, a valley, a dune, a river or stream, etc. ) Landscape: a collection of landforms seen from a high point (dunes, a beach, a stream, hills, etc. ) Weathering and erosion: the processes that form the landscapes range from the quiet disintegration of rocks to roaring mountain streams. Erosion: the other types of breakdown processes that includes transportation. Soil: the mixture of minerals, organic matter, gases, liquids, and the countless organisms that together support life on earth. Temperature, moisture, and wind are factors in the soil formation. Both moisture and high temperatures accelerate chemical reactions, and decomposition of organic matter in the soil. Wind is another factor in soil formation of certain areas where wind action adds find dust to existing soils. The role of worms and many other animals and plants in the formation of soils is well recognized today.
