Water-Related Landforms and Geological Features

A delta is formed when a river meets a larger body of water, such as an ocean or lake, and deposits its sediment. Over time, the sediment builds up and creates a fan-shaped landform.

A canyon is a deep, narrow valley with steep sides, typically formed by the erosive action of a river over a long period of time.

Karst is a type of cave system formed by the dissolution of soluble rock, such as limestone or dolomite, by water over a long period of time.

A fjord is a long, narrow inlet of the sea between high cliffs, typically formed by glacial erosion.

A mesa is a flat-topped mountain with steep sides, typically formed by the erosion of a plateau.

A geyser is a natural spring that emits hot water or steam.

A bog is a type of wetland characterized by standing water and a high concentration of organic matter.

A floodplain is a low-lying area of land that is periodically flooded by water.

A beach is a type of coastal landform formed by the deposition of sediment by waves and currents.

An ocean is a large body of salt water surrounded by land.

A cascade is a type of waterfall formed when a river flows over a steep drop in elevation.

A cave is a natural underground channel or passage formed by the action of water.

A sea stack is a type of coastal landform formed by the erosion of cliffs by waves and currents.

A meander is a large, slow-moving river that flows through a floodplain.

A spit is a type of coastal landform formed by the accumulation of sediment by waves and currents.
