Humans live on land, which has many forms and features that change from one region to another. A landform is a physical feature on the surface of our planet Earth. Landforms take shape over millions of years and have a significant connection with the environment and life.
Landforms can broadly be divided into three categories: mountains, plateaus, and plains.
Mountains are landforms that are much higher than the surrounding landscape. They are recognized by a broad base, steep slopes, and a narrow summit. Depending on their height, some mountains are permanently snow-capped.
Mountain slopes are often covered with montane forest, where conifer trees such as pines, firs, spruce, and deodar are common. These trees are tall, cone-shaped, and have thin, pointed leaves. At higher altitudes, trees give way to grasses, mosses, and lichens.
Mountain Fauna: Mountains are home to diverse animals, including the golden eagle, peregrine falcon, Canadian lynx, snow leopard, ibex, Himalayan tahr, mountain hare, yak, grey fox, and black bear.
The mountain terrain is rugged and steep, making regular farming difficult. Cultivation is practiced on slopes by cutting steps, known as terrace farming. Herding is often preferred over agriculture.
Tourism & Culture: Tourism is a major source of income (skiing, hiking, mountaineering, paragliding). Many traditional communities consider mountains sacred (e.g., Mount Everest is called 'Chomolungma' by Tibetans and 'Sagarmatha' by Nepalis; Mount Kailash is sacred to Hindus, Buddhists, Jainists, and Bon followers).
Challenges: Mountain life involves natural hazards such as flash floods, landslides, avalanches, cloudbursts, and extreme cold weather, alongside human-made challenges like uncontrolled tourism.
A plateau is a landform that rises up from the surrounding land and has a more or less flat surface, often with steep slopes on one or more sides.
Plains are landforms with an extensive flat or gently undulating surface, generally not more than $300\text{ m}$ above sea level.
Fertile plains have historically been the cradles of the first civilizations. Today, a large portion of the world's population lives in plains.
Deserts are large, dry expanses of land with very little precipitation. They have unique flora and fauna adapted to harsh conditions.
Ancient Tamil Sangam poetry classifies landscapes into five distinct tiṇais, reflecting a deep connection between humanity and nature:
| Tiṇai | Landscape | Main Occupation |
|---|---|---|
| Kuriñji | Mountainous regions | Hunting and gathering |
| Mullai | Grassland and forests | Cattle rearing |
| Marudam | Fertile agricultural plains | Farming |
| Neydal | Coastal regions | Fishing and seafaring |
| Pālai | Arid, desert-like regions | Journeying and fighting |
