Give examples of things that undergo deposition ?
Deposition occurs when a substance goes directly from the gas state to the solid state. Like sublimation, the intermediate liquid phase is skipped over. In contrast to sublimation, the process of deposition releases energy.
An example of deposition is the formation of frost. In cold temperatures, water vapor undergoes deposition to form a thin layer of solid ice on plants and grass.

Give examples of things that undergo deposition ?
Examples of things that undergo deposition:
Deposition is a geological process in which sediments, soil, or rock particles are added to a landform or landmass. This process occurs when the energy of transporting medium, such as wind, water, or ice, decreases and is no longer able to carry the particles. As a result, the particles settle and accumulate, forming various landforms. Here are some examples of things that undergo deposition:
1. Glacial Deposition:
Glaciers are large masses of ice that move slowly over the land. As glaciers move, they pick up rocks, soil, and debris. When the ice melts or recedes, these materials are deposited in the form of moraines, drumlins, and eskers. Moraines are ridge-like landforms composed of till (unsorted mix of clay, silt, sand, and rocks) deposited by glaciers. Drumlins are elongated hills formed by the deposition of glacial till. Eskers are long, winding ridges of sand and gravel formed by streams flowing within or beneath glaciers.
2. River Deposition:
When rivers flow, they carry sediments such as sand, silt, and clay. As the velocity of the river decreases, it loses its ability to transport these sediments, leading to their deposition. River deposition creates various landforms such as deltas, floodplains, and alluvial fans. Deltas are formed where rivers meet large bodies of water and deposit sediments, creating a triangular-shaped landform. Floodplains are flat areas adjacent to rivers that experience periodic flooding, resulting in the deposition of fertile sediments. Alluvial fans are fan-shaped landforms formed at the base of mountains or hills due to the deposition of sediments carried by fast-flowing streams.
3. Wind Deposition:
Wind can transport fine-grained particles like dust and sand over long distances. When the wind speed decreases, it drops these particles, causing deposition. The deposited sediments form landforms such as sand dunes and loess deposits. Sand dunes are mounds or ridges of sand formed by the wind's action and subsequent deposition. Loess deposits are fine-grained, wind-blown sediments that accumulate to form extensive and fertile plains.
4. Coastal Deposition:
Along coastlines, wave action and longshore currents carry and transport sediments. When the energy of the waves decreases, the sediments settle and deposit, forming beaches, spits, and barrier islands. Beaches are accumulations of sand or gravel along the shoreline. Spits are elongated landforms formed by the deposition of sediment that extends from the mainland into the sea. Barrier islands are narrow, elongated islands parallel to the coast, formed by the deposition of sediments by waves and currents.
In conclusion, deposition is a fundamental geological process that occurs in various environments. Whether through glacial, river, wind, or coastal processes, deposition leads to the formation of diverse landforms that shape our planet's surface.
