Land, also known as dry land, ground, or earth, is the solid terrestrial surface of Earth not submerged by the ocean or another body of water. It makes up 29.2% of Earth's surface and includes all continents and islands. Earth's land surface is almost entirely covered by regolith, a layer of rock, soil, and minerals that forms the outer part of ...
A landform is a natural or anthropogenic [1][2] land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and ...

There is no standard geological meaning for mountains. But it is usually defined as a landform that rises above anything around it, forming a steep slope and a pointed, relatively narrow summit. Generally, mountains are higher than hills. They are created through the action of incredible forces in the earth such as volcanic eruptions. Often, mounta...
A valley is a lowland area or surface depression of the earth between higher lands such as mountains or hills. In simple terms, it can be defined 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 created because of water or ice erosion. On this basis, the rivers or stre...
Plateaus are one of the major landforms. These are supposed to be fairly flat areas sharply higher than the land surrounding it. Plateaus are existent in every continent and cover almost one third of the earth’s periphery. The Qinghai-Tibetan plateau, located in central Asia is the highest and the largest plateau in the world. According to National...
Glaciers are the perennial ice sheets on the planet. They are huge masses of ice that slowly move over the land or ocean surface. Glaciers are predominantly seen in the peaks of high mountains and in the cold Polar Regions. Low temperatures and consistent snowfall for millions of years in the regions are the enabling factors for the buildup of thes...
Hills are raised landforms on the face of the earth with distinctive, usually rounded summits, but are not as high as mountains. The height of a hill on average never exceeds 300 meters or 1000 feet. Hills are created as a result of accumulation of rock debris or sand deposited by wind and glaciers. They can also be created by faulting, when the fa...
Loess is a fine-grained unstratified accumulation of clay and silt deposited by the wind. It appears brown or yellow in color and is brought about by past glacial activities in an area. The thickness of loess deposits are just a few meters and one of their basic features is known as the ‘cat steps’. It’s held together by few clay particles and is m...
Plains are broad flat areas on the earth’s surface stretching over a wide territory. They cover more than one-third of the total land area on earth. Plains are lower than the land in their surrounding and can be found both inland and along the coast. Coastal plains rise from the sea level up to the point where they meet raised landforms such as pla...
Deserts are the hot and dry areas of the world. They are the arid and semi-arid lands with little or no vegetation. Deserts constitute approximately 20% of the earth’s total land and are distinguished by little or zero rainfall. The deserts are divided into four major categories including the Semi-Arid Deserts, the Hot and Dry Deserts, the Cold Des...
Rivers are the largest stream of water that flows through land and descend down to other water bodies like ocean, lake or other rivers. Rivers are not exactly landforms but parts of other landforms like mountains, prairies and valleys. The Mississippi and Missouri of the USA, The Nile of Egypt or The Ganges of India are good examples of Rivers. Riv...
Oceans are huge water sources. The reason for regarding oceans as landforms is its vastness; which covers three-fourth or 71% of the earth surface. During the degassing era, when the newly formed earth started to cool down, the hydrogen atoms inside the gas started to reform as rain water. These rainwaters poured down to the earth basins and filled...
Jun 24, 2024 · Land, also known as dry land, ground, or earth, refers to the solid terrestrial surface of the Earth that is not submerged by water. It encompasses the continents, islands, and all the natural features and resources on the Earth’s surface. Land is an essential component for various human activities and supports diverse ecosystems and habitats.
Jul 3, 2023 · Landforms are natural features that shape the Earth's surface. They are the result of various geological processes and can be found across the planet, encompassing a wide range of shapes, sizes, and formations. Landforms provide valuable insights into the Earth's history and are crucial in understanding the dynamic processes that have shaped ...
The terrain of the land surface varies greatly and consists of mountains, deserts, plains, plateaus, and other landforms. The elevation of the land surface varies from a low point of −418 m (−1,371 ft) at the Dead Sea, to a maximum altitude of 8,848 m (29,029 ft) at the top of Mount Everest. The mean height of land above sea level is about ...

Our home planet Earth is a rocky, terrestrial planet. It has a solid and active surface with mountains, valleys, canyons, plains and so much more. Earth is special because it is an ocean planet. Water covers 70% of Earth's surface. Earth's atmosphere is made mostly of nitrogen and has plenty of oxygen for us to breathe.
