Many of Earth's landforms and landscapes are the result of weathering, erosion and redeposition. Weathering is a crucial part of the rock cycle; sedimentary rock, the product of weathered rock, covers 66% of the Earth's continents and much of the ocean floor. [4]
Erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust and then transports it to another location where it is deposited. Erosion is distinct from weathering which involves no movement.
Coastal erosion is the loss or displacement of land, ... Corrosion or solution/chemical weathering occurs when the sea's pH (anything below pH 7.0) ...
Honeycomb weathering – Form of cavernous weathering and subcategory of tafoni; Impact crater – Circular depression in a solid astronomical body formed by the impact of a smaller object; Joint valley – Landscape originates from the erosion of joints in the bedrock, leaving out small plateaus or ridges in between. Common in Fennoscandia.
Abrasion is a process of weathering that occurs when material being transported wears away at a surface over time, commonly occurring with ice and glaciers. The primary process of abrasion is physical weathering. Its the process of friction caused by scuffing, scratching, wearing down, marring, and rubbing away of materials.
Weathering and erosion break the original rock down into smaller fragments and carry away dissolved material. This fragmented material accumulates and is buried by additional material. While an individual grain of sand is still a member of the class of rock it was formed from, a rock made up of such grains fused together is sedimentary.
With time, erosion of the soft layer causes the cap to be undercut, eventually falling off, and the remaining cone is then quickly eroded. [14] [15] Typically, hoodoos form from weathering processes that continuously work together in eroding the edges of a rock formation known as a fin.
