"Weathering is the deterioration of rocks, soils and minerals as well as wood and artificial materials through contact with water, atmospheric gases, and biological organisms."
An exploration of the processes of weathering and erosion, how they affect the landscape, and the different types of weathering and erosion, such as chemical, physical, and biological weathering.
Plate Tectonics: The scientific theory that explains how the Earth's crust moves and some of the forces that cause weathering and erosion.
Weathering Processes: The physical, chemical, and biological processes that break down rocks and minerals into smaller particles.
Erosion Processes: The processes by which weathered materials are transported, often by water, wind, ice or gravity.
Soil Formation: Processes that occur when weathered materials accumulate and create layers of soil over time.
Glacier Formation and Movement: The ways in which glaciers form and move, and the resulting landscape features created by glacial erosion.
Coastal Processes: The interaction of coastal landforms with the sea and the processes which shape and erode these features.
Fluvial Processes: The processes that occur in rivers, such as erosion, sediment transport, deposition, and channel formation.
Landform Evolution: The long-term processes that shape landscapes, including weathering, erosion, and sedimentation.
Mass Wasting: The movement of soil and rock downhill under the influence of gravity.
Human Impact on Geomorphology: The ways in which human activities have affected the land and altered natural processes, such as deforestation and land conversion.
Rock Types and Geology: How the different types of rocks and geology affects weathering and erosion processes.
Climate Change and Geomorphology: How climate change is impacting landforms and the associated weathering and erosion processes.
Karst Topography: The unique landscape features that result from the dissolution of limestone and other soluble rocks.
Coastal Erosion: The erosion and weathering on coastlines due to the marine processes like waves, tides and currents.
Fluvial Erosion: The erosion and weathering of a river or stream's bed and banks, and the erosion caused by the flow of water in rivers or streams.
Wind Erosion: The process by which wind lifts and carries materials, such as sand, in the landform.
Biological Weathering: The process of breaking down rocks and landforms by living organisms like plants and animals.
Chemical and Physical Weathering: The processes by which changes in temperature, water flow, and exposure to chemicals break down rocks and landforms.
Sediment Transport and Deposition: The process of sediment movement and accumulation, including by rivers and coastal currents.
Volcanic Erosion: The process of erosion and weathering of a landform or rock that has resulted from volcanic activity.
Mechanical weathering: The process of breaking down rocks into smaller pieces without changing their chemical composition.
Chemical weathering: The process of breaking down rocks by changing the chemical composition of minerals.
Biological weathering: The process of breaking down rocks by the action of plants, animals, and microbes.
Water erosion: The process of wearing away rocks and soils by water flow and movement.
Wind erosion: The process of moving and abrading soil particles by wind.
Glacier erosion: The process of transporting rocks and soil by glaciers through abrasion.
Coastal erosion: The process of wearing away rocks, soil, and minerals along coastal areas by waves and tides.
Mass wasting: The process of the downhill movement of soil and rocks due to gravity.
Chemical erosion: The process of dissolving rocks by chemical processes, such as acid rain.
Thermal erosion: The process of wearing away rocks and soil due to temperature changes, such as freezing and thawing.
"...agents such as water, ice, snow, wind, waves and gravity."
"Weathering occurs in situ (on-site, with little or no movement), and so is distinct from erosion, which involves the transport of rocks and minerals..."
"Weathering processes are divided into physical and chemical weathering."
"Physical weathering involves the breakdown of rocks and soils through the mechanical effects of heat, water, ice, or other agents."
"Chemical weathering involves the chemical reaction of water, atmospheric gases, and biologically produced chemicals with rocks and soils."
"Water is the principal agent behind both physical and chemical weathering..."
"...though atmospheric oxygen and carbon dioxide and the activities of biological organisms are also important."
"Chemical weathering by biological action is also known as biological weathering."
"The materials left over after the rock breaks down combine with organic material to create soil."
"Sedimentary rock, formed from the weathering products of older rock, covers 66% of the Earth's continents..."

"Physical weathering involves the breakdown of rocks and soils through the mechanical effects of heat..."
"Physical weathering involves the breakdown of rocks..."
"agents such as water, ice, snow, wind, waves, and gravity."
"Many of Earth's landforms and landscapes are the result of weathering processes combined with erosion and re-deposition."
"Rocks, minerals, and artificial materials"
"...and much of its ocean floor."
