Sand DunesSand dunes are heaps of sand deposited at a place by the wind’s action in thedesert areas.

Flood plains are formed in the following manners: During rains rivers overflow their banks. This leads to the flooding of the nearby areas. After the flood has receded, a layer of fine material and other material is deposited over the plain in the form of sediments. This leads to the formation of the flood plain.

ErosionErosion is the wearing away of the landscape by different agents like running water, glacier, wind, ground water and sea waves.

Plates move due to the movement in the molten magma found in the interior of the earth. Exogenic Forces Exogenic forces are those forces which act on the surface of the earth and causechanges on the surface of the earth.Examples: Weathering, gradation, erosion, deposition. Endogenic Forces Endogenic forces are those forces which originate in the interior …

The oceanic crust is subducted under the continental as it is naturally denser than the continental crust. When a continental plate collides with an oceanic plate, the oceanic plate crust subducts beneath the continental crust due to its high density and its higher specific gravity, thus forming a subduction zone.

Geologic processes such as plate tectonics impact the entire surface of the planet and have major influences on the location of natural hazards like earthquakes and volcanoes. So far, we have only studied large scale patterns in plate tectonics.

Headlands are characterised by high, breaking waves, rocky shores, intense erosion, and steep sea cliff. Headlands and bays are often found on the same coastline. A bay is flanked by land on three sides, whereas a headland is flanked by water on three sides.

A beach forms when waves deposit sand and gravel along the shoreline. and pebbles. Over time they are worn smooth from being rolled around by waves. The rocks usually reflect the local geology.

flat fertile flood plains. (v) Sand dunes are low hill-like structures formed by the deposition of sand in the deserts. (vi) Beaches are formed when the sea waves deposit sediments along the shores of the sea.

Hydraulic action is the erosion that occurs when the motion of water against a rock surface produces mechanical weathering. Most generally, it is the ability of moving water (flowing or waves) to dislodge and transport rock particles.
