Deposition science refers to the geological process in which sediments, soil, and rocks are added to a landform or landmass). Deposition can occur through various agents such as wind, ice, water, and gravity, which transport previously weathered surface material). Deposition can also refer to the buildup of sediment from organically derived matter or chemical processes). Here are some key points about deposition science:

• Causes: Deposition occurs when agents of erosion, such as wind or water, lay down sediment into new areas.

• Process: Deposition is a constructive process that changes the shape of the land. The deposition process consists of two phases: erosion and deposition.

• Types: Deposition can occur in various forms, such as delta formation, where rivers empty their water and sediment into another body of water, creating new landforms. Other types of deposition include alluvial fans, which are created when sediment carried by a mountain stream is deposited due to a rapid change in slope from a high to a low gradient.

• Examples: Deposition happens wherever there is wind or moving water. For example, rivers deposit sediments in a fan-shaped delta where they empty into the ocean. Wind can layer tiny particles of silt to create large sediment layers called loess.

Deposition science is a natural geological process that transports sand, silt, and sediment from one place and deposits it in another. Depositions overall effect is positive on earth, as it can form new islands and increase agricultural output.
