How Landforms Are Formed

Landforms are natural physical features on Earth's surface formed by geological processes. They include mountains, which form from tectonic movements, volcanoes, and erosion, as well as valleys, islands, dunes, deserts, plains, peninsulas, rivers, and plateaus. Landforms can be created rapidly through events like volcanic eruptions or slowly over millions of years from the wearing down of rock by forces of nature such as wind, water, and ice.

HOW LANDFORMS Landforms

ARE FORMED The surface of earth is a collaboration of the various physical features. These
natural physical features on the earth’s surface called as landforms.  Landforms
Dunes are defined as the natural physical features found on the surface of the earth
Dunes are mounds or small hills made up of sand that are created created as a result of various forces of nature such as wind, water, ice, and
due to the action of and water flow (under water dunes). It may be movement of tectonic plates. Some landforms are created in a matter of few
dome-shaped, crescent-shaped, star-shaped, linear-shaped, and hours, while others take millions of years to appear.
many more. The height of a dune hill can be as low as 1 meter, or
as high as 10 meter and more.
Mountains
Mountains are landforms higher than the surrounding areas. They are formed
due to the tectonic movements, earthquakes, volcanic eruptions and erosion of
Islands the surrounding areas caused due to wind, water and ice. Mountains are found
An island is a piece of land which is surrounded by water from all in the oceans and on land.
sides and formed either due to volcanic eruptions or due to hot
spots in the lithosphere.
Plateaus
Plateaus are flat highlands that are separated from the surroundings due to
steep slopes. They are formed by collisions of tectonic plates, magma action that
causes the elevation in earth’s crust

Valleys
Valleys are low-lying areas of land between hills and mountains that are formed
due to the actions of glaciers and rivers over millions of years. Depending on the
shape they are classified as V shaped valleys and U shaped valleys. V-shaped
valleys are formed by the flowing rivers and U-shaped valleys are formed due to
glaciers.

Deserts
Due to lack of adequate rainfall, desert is a dry piece of land with little or no
vegetation. They are mostly found mainly in rain shadow areas which are
leeward of a mountain range with respect to the wind direction. In deserts, the
atmospheric air is very dry, and daytime temperature is high.
Rivers
Rivers are natural flowing streams of fresh water descending from
mountains. They mostly flow toward a lake, sea, ocean or another river. Plains

Plains are flat or the low relief areas on the surface of the earth. It might be
Peninsulas
formed as a result of the sedimentation of eroded soil from the top of the hills
Peninsulas are large land areas that extend into water bodies. They
and mountains or might be due to flowing lava deposited by the agents of wind,
remain surrounded by water on three sides. Peninsulas are formed by
water, and ice.
