Hey everyone,for now i have a new inquiry question that is on land forming processes,
What is a land form?
A landform is a natural feature on the landscape,any natural forming rocks or dirt,natural physical features of the earth’s surfaces examples; valleys, plateaus, mountains, plains, hills,canyon, loess, or glaciers.Landform together make up a given terrain and their arrangement in the landscape make up a topography.Major types of land forms on the earth include mountains,valleys,plateaus,glaciers,hills,Loess,plains and desert.
Mountains are lands physical features cantilever high exceeding the hills and very high up the land surface with steep top routinely shaped up to a peak. They are created through the action of incredible forces in the earth such as like volcanic eruptions.Many a times, mountains occur in the ocean compared in the land and some are seen as mountain islands as their peaks exceed out of the water. Mountain formation culminate from the forces of erosion, volcanicity, or uplifts in the earth’s crust
A valley is a lowland area or surface depression of the earth between higher lands such as like mountains or hills. In simple way, it can be definition as a natural trough bounded by mountains or hills on the surface of the earth sloping down to the lake, ocean or stream, which is formed because of water or ice erosion. On this basis, the rivers or streams flowing through the valley empty the land’s precipitation into the oceans.
Plateaus are fairly flat areas exorbitant than the land surrounding it. The surrounding areas may have very steep slopes. Some plateaus such as the Tibet are situated between mountain ranges. Plateaus cover wide land areas and together with their enclosed basins they covers approximately 45% of the complete earth’s land surface.
Glaciers are the perennial ice sheets on the earth. They are huge masses of ice that slowly move over the land surface, preeminent in high mountains and the cold Polar Regions. The very modest temperatures in the regions are the enabling factor for the growth of snow and densification into ice.
Hills are embossed areas on the surface of the earth with distinctive summits, but are not as high as mountains. Hills are created as a consequence of accumulation of rock debris or sand deposited by wind and glaciers. They can also be formed by faulting when the faults go slightly upwards. Hills are generally present in areas like low mountain valleys and plains.
Loess is a fine-grained unstratified accumulation of clay and silt deposited by the wind. It appears brown or yellowish in color and is brought about by olden glacial activity in an area. It is sedimentary deposits of clay and silt mineral particles which take place on land in some parts of the world. The thickness of loess deposits are a few meters and one of their basic feature is known as the ‘cat steps’.
Plains are broad flat areas on the earth’s surface stretching over in a wide area. Plains are lower than the land in their surrounding and can be found both inland and along the coast. Coastal plains rise up from the seal level up to the point they meet raised landforms such as plateaus or mountains. The Atlantic Coastal plain is an example of a substantially populated and fertile coastal plain.
Deserts are the hot and dry areas of the world. There are the arid and semi-arid lands with little or no vegetation. Deserts constitute approximately 20% of the earth’s total land cover and are differentiated by little or no rainfall. The deserts are divided into four major categories including the;Semi-Arid Deserts, the Hot and Dry Deserts, the Cold Deserts, and the Coastal Deserts.
Here are the sites i got my research;
