Erosion followed by deposition is the process by which sediment that has been eroded and transported by natural agents like water, wind, or ice is laid down in new locations. This process helps shape the Earth's surface by reshaping and forming landscapes over time.
An angular unconformity represents a period of deformation and erosion followed by deposition of new sedimentary layers. The lower older layers are tilted or folded indicating tectonic activity, followed by erosion that removed some of the rock layers. Subsequently, new horizontal layers were deposited on top of the eroded surface, creating an angular unconformity between the older deformed layers and the younger horizontal layers.
The strongest agents of erosion are glaciers, followed by rivers, waves, wind, and finally, gravity. Glaciers are capable of shaping entire landscapes through their movement and carving ability, while gravity causes mass movements like landslides and rockfalls. Rivers, waves, and wind also play significant roles in shaping the Earth's surface through erosion.
The five types of erosion are water erosion, wind erosion, glacier erosion, wave erosion, and mass movement erosion. Each type of erosion is caused by different forces and processes that wear away or transport soil and rock material from one place to another.
Three transporting agents of erosion are water, wind, and ice. Water erosion is caused by rivers, streams, and rainfall, while wind erosion occurs in arid and windy environments. Ice erosion, known as glacial erosion, is caused by the movement of glaciers.
The 3 main types of glacial erosion are plucking, abrasion and freeze thaw.
deposition
Early volcanic activity, uplift and erosion followed by glaciation and further erosion.
Weathering, erosion, deposition, compaction, and cementation.
Elevation change in the terrain where the river flows, followed by erosion that slowly created the falls

Sand that is overlayed by additional sediments will experience compaction. Small gaps between sand particles will fill in with minerals which cement the particles together. The process takes a long, long time.

Types of erosions include sheet erosion, rill erosion, gully erosion, and streambank erosion. Sheet erosion occurs when a thin layer of soil is removed by rainfall or runoff, while rill erosion creates small channels in the soil. Gully erosion forms larger, deeper channels, and streambank erosion refers to the wearing away of soil along river or stream banks.
