1) The rise and fall of water caused by friction of wind on water, is commonly known as a 'wave'. They are also known as wind waves, surface waves etc. and are found on seas, lakes, ponds etc.

2) flow of water in streams, rivers, and other channels, and is a major element of the water cycle. ... The discharge of water flowing in a channel is measured using stream gauges or can be estimated by the Manning equation. The record of flow over time is called a hydrograph.

3) Steep perpendicular face of a rock along a sea coast is called Cliff.

4) The debris of boulder and coarse material carried by a glacier is known as End Moraine or Terminal Moraine. It is found usually at the end of the glaciers as sheets or piles of debris when the glacier melts.

5) A crescent-shaped lake formed when a meander of a river or stream is cut off from the main channel.

6) The sediment in wind causes erosion by abrasion. Sand dunes form when the wind deposits sand. Loess form when the wind deposits clay and silt. Wind erosion can be prevented by keeping the ground covered with plants.

7) An isolated free standing column of rock near the coast is called a stack.

8) The river mouth is where much of this gravel, sand, silt, and clay—called alluvium—is deposited. When large amounts of alluvium are deposited at the mouth of a river, a delta is formed. ... These sediments form the flat, usually triangle-shaped land of a delta.
