Test: Various Landforms - Delhi Police Constable MCQ

Landforms are natural features that make up the Earth's surface, such as mountains, valleys, plains, and plateaus.

Canyons are formed through erosion by rivers or glaciers, cutting through the land over time.

The Grand Canyon was primarily formed by the Colorado River cutting through layers of rock over millions of years.

Mountains are high landforms with a peak or summit that rises significantly above the surrounding terrain.

The Himalayas are mainly located in the continent of Asia, spanning several countries including India, Nepal, Bhutan, and China.

Valleys are often formed through the movement of tectonic plates, which can create rifts and depressions in the Earth's crust.

Sand dunes are depositional landforms formed by the accumulation of sand through wind action.

The process of breaking down rocks into smaller particles by natural forces is known as weathering. 

• Weathering involves the disintegration of rocks through physical, chemical, or biological processes.


• It occurs due to factors like temperature changes, water, wind, and biological activity.


• Physical weathering breaks rocks mechanically, while chemical weathering alters their chemical structure.


• Biological weathering involves plants and animals contributing to rock breakdown.

Weathering is fundamental in soil formation and landscape changes.

Fjords are formed by glacial erosion, where glaciers carve out deep, U-shaped valleys that become flooded by seawater.

Plateaus are flat, elevated areas above sea level, often with steep slopes and step-like appearance.

Weathering refers to the mechanical and chemical breakdown of rocks into smaller particles and is a key factor in the formation of various landforms.

Sandbars are coastal erosional landforms that are long, narrow ridges of sand formed by the action of waves and currents.

Erosion is the process by which soil and other materials are carried away by natural forces like water and wind.

Deltas are landforms formed by the deposition of sediment carried by a river as it enters a larger body of water, such as a sea or lake.

Submergence refers to the process of land being submerged under water, often due to rising sea levels.

Plains are flat, extensive landforms with fertile soil, making them ideal for agricultural activities.

Orogeny refers to the process of mountain-building through the collision of tectonic plates.

Eskers are long, winding ridges of gravel and sediment formed by the melting of icebergs and glaciers.

River erosion is the process by which a river wears away its banks and bed, leading to the deepening and widening of its valley over time.

The Great Barrier Reef is primarily located off the coast of Australia and is one of the most significant coral reef systems globally, known for its rich biodiversity and natural beauty.
