There are two main types of weathering: mechanical/physical weathering and chemical weathering. Mechanical/physical weathering includes exfoliation, ice wedging, organic wedging, and abrasion which break rocks into smaller pieces through forces like heat, freezing water, plant and animal activity, and rocks rubbing together. Chemical weathering involves processes like hydrolysis, oxidation, dissolution, and reactions with acids that cause rocks to decompose and break down on an atomic scale when in contact with water and acids from sources like carbon dioxide, pollution, and decaying plants.
Physical weathering breaks rocks down mechanically through processes like frost wedging and thermal stress weathering. Chemical weathering involves the decomposition of minerals through reactions with water, oxygen, and acids. Biological weathering occurs through processes assisted by living organisms, such as root growth and acid production. The main types of weathering processes that break down rocks are physical, chemical, and biological weathering.
The document discusses factors that influence the rate of weathering of rocks, including climate, rock characteristics, and vegetation. It notes that chemical weathering is most intense in hot, wet climates while physical weathering is more active in cold climates. Certain rock textures like joints, bedding planes, and porous/permeable rocks weather more easily. The presence of vegetation also promotes weathering through organic acids and by holding moisture against rock surfaces.
Weathering is the process of decomposing, breaking up, or changing rocks without moving them from their original location. Erosion is the process of moving weathered rock and soil particles from their original location by forces like wind, water, or ice. Weathering can occur through chemical processes that alter the minerals in rocks or through mechanical processes that break rocks into smaller pieces without changing the minerals. Once weathered, smaller rock pieces can be eroded and transported elsewhere by natural forces.

Erosion then transports this weathered material, which is deposited in new locations through various agents such as running water, glaciers, wind, and ocean waves. This forms new landforms and shapes the Earth's surface over time through the continuous weathering, erosion, and deposition cycle.
Lecture and study guide rocks, soils, erosion, weathering and depositionKella Randolph
This document provides an overview of rocks, soils, erosion, weathering, and deposition. It discusses the three main types of rocks - igneous, sedimentary, and metamorphic - and how they are formed. Soil formation through weathering and the layers of the soil profile are explained. Various agents and processes of erosion, weathering, and deposition are defined. Methods for controlling erosion like contour farming, terracing, and planting vegetation are also outlined. The key message is the importance of protecting natural resources and keeping the earth healthy.
This document discusses different types of erosion and how they shape landscapes. It describes four primary types of erosion caused by water: splash, sheet, rill, and gully erosion. Moving water such as streams and oceans erode cliffs, coastlines, and river banks through hydraulic action, corrosion, and impact. Wind erosion shapes desert landscapes and forms arches and sand dunes. Glaciers erode through abrasion, plucking, and thrusting, carving out mountain valleys and leaving moraines. Mass movement and exfoliation also contribute to gravitational erosion. Factors like precipitation, vegetation, and human activities affect erosion rates. Terracing and windbreaks can help prevent erosion.
The document discusses various exogenic (surface) processes including weathering, mass wasting, and soil erosion. It describes three main types of weathering - physical, chemical, and biotic weathering. Physical weathering breaks rocks into smaller pieces through mechanical processes like heating/cooling or frost action without changing the chemical composition. Chemical weathering alters the chemical makeup of rocks through oxidation, carbonation, hydration, or solution. Biotic weathering is caused by living organisms through root growth, burrowing, or human activities. Mass wasting and soil erosion are also exogenic processes that transport weathered material downslope or remove soil faster than replacement through water, wind, ice, or gravity.
