What we call a mountain range one day can be a valley the next. There are four main categories of landforms, and these are mountains, hills, plateaus, and plains. Buttes, canyons, valleys, and basins all qualify as minor landforms. The mountain formation process is itself is an astonishing act.

The mountain at the top of the list is Mount Everest in Nepal. It is located at an elevation of 8,850 metres (29,035 ft). It is a section of the Himalayas, which spans a number of Asian countries.

Types of land

Plains

The majority of the Earth's surface is made up of low and high plains, which can be distinguished from one another by having a mainly level profile that can range from having gentle rolling hills to being completely flat. The "floodplains" and deltas of big rivers, as well as the Atlantic-Gulf Coastal Plain of the United States, are typical examples of the types of landforms that can be found in regions with considerable sediment accumulation.

Plateaus

It is possible to think of plateaus as elevated plains, which would be elevated flattish places. Plateaus are surrounded on at least one side by lower-lying ground and frequently have rather steep scarps along their edges. These landforms could have originated from very ancient mountains that were worn down by erosion over time, while others could have been formed by block faulting.

Valleys, Canyons and Caves

The carving of valleys is typically a collaborative effort between faulting and the eroding action of rivers and glaciers, which are moving masses of ice. These glacially carved troughs often come to sustain lakes, such as in the Finger Lakes region of New York State. Glaciers have a tendency to carve valleys in the shape of a U as they move along drainages. In contrast, running water has a tendency to carve out valleys in the shape of a V.

Deserts

The ecological landscapes that are known as deserts are characterised by extremely arid conditions, with low precipitation and high evaporation. Deserts typically feature abundant mountains, plains, plateaus, and canyons, all of which are distinct sub-varieties of desert landforms. Deserts are defined by their extremely arid conditions. These landscape features include dried lakebeds, gravel plains, and sand dunes. Deserts are the result of a complex interaction between numerous natural elements, the most important of which is the climate both now and in the past.

Mountains

Mountains are massive formations that rise to a height that is significantly higher than the surrounding terrain and typically create pointed peaks. Tectonic activity is the process by which the movement of the Earth's tectonic plates results in the formation of most mountains.

How are mountains formed?

How are mountains formed

In a process known as plate tectonics, the largest mountain ranges in the world are formed when two or more portions of the Earth's crust, called plates, collide with one another and buckle up like the hood of a vehicle in a head-on collision. Around 55 million years ago, a catastrophic event began that would eventually become the Himalaya Mountains in Asia. The Himalayas are home to 30 of the tallest mountains on Earth. Mount Everest's peak, at an elevation of 29,035 feet (8,850 metres), is the planet's highest point.

Mauna Kea, an inactive volcano on the island of Hawaii in the Pacific Ocean, holds the record for vertical height. It is estimated that the peak of Mauna Kea is only 13,796 feet (4,205 metres) above sea level, yet its base is a whopping 33,474 feet (10,203 metres).

Let us learn more about the types of mountains.

Category of Mountains

Volcanic mountains

 Volcanic mountains are a distinct class of mountains. A volcano is a vent or aperture through which magma, ash, gases, and water vapour are thrown out. Volcanic mountains consist of - Magma chamber, Vent, Lava, Crater, and pyroclastic flow.

Volcanic soil or the land near a volcanic mountain is particularly fruitful. This is because all the needed nutrients come out with the volcanic eruption. Volcanic mountain or volcano may be active, dormant or extinct, based on the level of its activity.

Fold mountains

The movement and collision of tectonic plates on the earth's crust can be traced back to the formation of this type of mountain. The land in between the plates, which has been squeezed and has a tendency to fold as a result of the collision of the plates, These folds will eventually reach a very great height and culminate in the formation of the fold mountains. The Himalayas are an excellent illustration of such a range of mountains.However, it came into existence as a result of a collision between the Indo-Australian tectonic plate and the Asian tectonic plate.

Block Mountains

Because of the additional strain exerted by the lands on either side, a fault block in the ground has risen to a level that is higher than the sea. Horsts is the term used to describe when it rises to build taller blocks. Grabens are what you get when the fault collapses and forms troughs instead of ridges. Meanwhile, the Sierra Nevada in the United States of America is the best example.

 Residual Mountains

As their name suggests, the leftover mountains are the consequence of erosion that occurred over a period of billions of years. The effects of erosion have shrunk the scale of these mountains, which were once much larger. Denuded mountains is another name for these types of mountains. Meanwhile, the best instances of this are found in the Highlands of Scotland, the Balkan Peninsula, and the Scandinavian Mountains.

The Domes Mountains

Magma globs that float to the earth's crust and push the surface underneath can cause a big dome to form that is composed of very hard rocks. The crust of the planet expands as a result of this natural phenomena. This expansion will eventually result in the formation of a mountainous dome. The Black Hills of South Dakota, which are located in the United States of America, are an excellent example.

These concepts students learn in schools in their geography lesson. For clear understanding Online tuition classes are also available in geography and other subjects such as sociology online tuition for students to get clear and well informed understanding.
