Geomorphic Processes

Seif is similar to barchan but it has only one wing or point.

The breaking down of rocks by the action of wind, water and climate is called weathering.

No,  people and animal also cause soil erosion. People cause it by cutting down of trees and animals cause it by over grazing the fields. So this is a wrong statement.

This is a right answer. Soil conservation is protecting the soil from erosion.  Land slide is the sliding away of loose rocks down the slope of a hill. Soil erosion is the removal of top soil by natural forces like wind water and rain and deposition of top soil into rivers and lakes is called silting.

A canyon is a deep ravine between cliffs often carved from the landscape by a river. Rivers have a natural tendency to reach a baseline elevation, which is the same elevation as the body of water it will eventually drain into, forming a canyon. 

'Bay' is a body of water forming an indentation of the shoreline, larger than a cove but smaller than a gulf. 'Fjord' is a long, narrow, deep inlet of the sea between high cliffs. 'Isthmus' is a narrow strip of land, bordered on both sides by water, connecting two larger bodies of land.

Meanders are characteristic features formed by rivers as they erode and deposit sediment on alternating banks, creating curved or winding channels. Moraines are glacial features, inselbergs are isolated rock hills, and cirques are glacially carved amphitheater-shaped valleys.

Weathering is the in-place breakdown and decomposition of rocks through exposure to atmospheric agents like water, temperature changes, and chemical action. Erosion involves the removal and transport of weathered material. Denudation is the combined process of weathering and erosion.

Hydrogeology (hydro- meaning water, and geology meaning the study of the Earth) is the area of geology that deals with the distribution and movement of groundwater in the soil and rocks of the Earth's crust (commonly in aquifers).

Removal of the soil by the action of wind and water is known as erosion.

Soil is formed when rocks are broken down by the action of wind, water and climate. This process is called weathering.

The phenomenon of absorption of water by soil is termed percolation.

This is the correct answer. Loosening and turning of soil is called tilling or ploughing. This is done by using a plough, which is either drawn by a pair of bulls or driven by a tractor.

A delta is a landform formed at the mouth of a river where it deposits sediment as it flows into a larger body of water like an ocean or lake. The river slows down, dropping its load of silt, sand, and clay, creating a triangular or fan-shaped low-lying plain. Pediplains are erosional plains, peneplains are nearly flat erosion surfaces, and coastal plains are broader features along coasts.
