What is the process of creating new land known as?

The process of creating new land is known as reclamation. This term refers to various methods used to obtain land from a water body, usually through filling in coastal areas, wetlands, or other bodies of water. Reclamation can involve the use of materials such as soil, rocks, or other construction materials to elevate land above the water level, making it suitable for various uses such as agriculture, housing, or industrial purposes.

Tides, beaches, and spits are related to coastal processes and landforms but do not describe the act of creating new land. Tides refer to the regular rise and fall of sea levels caused by the gravitational pull of the moon and sun, affecting coastal areas but not creating new land. A beach is a landform along the shoreline composed of loose particles like sand, pebbles, or cobblestones, shaped by wave action, and does not involve the construction of new land. A spit is a coastal feature formed by the accumulation of sediment extending into the water, creating a narrow landform, but does not encompass the broader concept of land reclamation. Thus, reclamation specifically captures the idea of generating new land from water, making it the correct answer.
