Explanation:

Loess: It is an unstratified, geologically recent deposit of the silty or loamy material that is generally buff or yellowish brown in colour and is mainly deposited by the wind. Loess is a sedimentary deposit comprises largely of the silt-size grains that are loosely cemented by calcium carbonate. It is generally homogeneous and highly porous and is traversed by the vertical capillaries that permit the sediment to fracture and form the vertical bluffs.

Tombolo: A tombolo, sometimes interpreted as ayre, is a deposition landform in which an island get attached to the mainland by a narrow portion of land like a spit or bar. Once attached, the island is then called as a tied island. A tombolo is the sandy isthmus. Several islands combined together by bars which rises above the water level are known as a tombolo cluster. Two or more tombolos may form an enclosure (known as a lagoon) that can eventually fill with sediment.

Point bars: A point bar is a depositional feature formed of alluvium that accumulates on the inside bend of the streams and rivers below the slipoff slope. Point bars are situated in the abundance in mature or meandering streams. They are crescent-shaped and found on the inside of a stream bend, being very similar to, though even smaller than, towheads, or river islands. A point bar is an part of deposition whereas a cut bank is an area of erosion. Point bars are made as the secondary flow of the stream sweeps and rolls sand, gravel and small stones laterally across the floor of the stream and up to the shallow sloping floor of the point bar. 

Moraines: A moraine is any kind of glacially formed accumulation of unconsolidated glacial debris (regolith and rock) that happens in both the www.gradeup.co 57 currently and formerly in the glaciated regions on Earth (i.e. a past glacial maximum), by the geomorphological processes. Moraines are formed from the debris previously carried along by a glacier, and generally consists of somewhat rounded particles ranging in size from the large boulders to minute glacial flour. Lateral moraines are made at the side of the ice flow and terminal moraines at the foot, labeling the maximum advance of the glacier.
