In geology and physical geography , a plateau ( / p l ə ˈ t oʊ , p l æ ˈ t oʊ , ˈ p l æ t oʊ / ; French: [plato] ; pl. : plateaus or plateaux ), also called a high plain or a tableland , is an area of a highland consisting of flat terrain that is raised sharply above the surrounding area on at least one side. Often one or more sides have deep hills or escarpments . Plateaus can be formed by a number of processes, including upwelling of volcanic magma , extrusion of lava , and erosion by water and glaciers . Plateaus are classified according to their surrounding environment as intermontane, piedmont, or continental. A few plateaus may have a small flat top while others have wider ones.

After Indian Independence in 1947, majority of the region was organised into four states Bombay State , Hyderabad State , Madras State , and Mysore State . The Reorganisation of Indian states on linguistic lines in the 1950s resulted in the creation of the states of Andhra Pradesh , Karnataka , Kerala , Maharashtra , and Tamil Nadu . Telangana

Bhakri made of millets and roti or chapathi made of wheat served with dal are popular in the north and western parts of the region. Idli and dosa served with sambar and chutney for breakfast and rice served with sambar and rasam for lunch are popular in
300-542: A river was already there, though not necessarily on exactly the same course. Then, subterranean geological forces caused the land in that part of North America to gradually rise by about a centimeter per year for millions of years. An unusual balance occurred: the river that would become the Colorado River was able to erode into the crust of the Earth at a nearly equal rate to the uplift of the plateau. Now, millions of years later,

Geographers have defined the extent of Deccan region using various physical features and indices such as rainfall, vegetation, or soil type. As per

The parallel Sierra of Andes delimit one of the world highest plateaux: the Altiplano , (Spanish for "high plain"), Andean Plateau or Bolivian Plateau. It lies in west-central South America, where the Andes are at their widest, is the most extensive area of high plateau on Earth outside of Tibet. The bulk of

Another example is the Highveld which is the portion of the South African inland plateau which has an altitude above approximately 1,500 metres, but below 2,100 metres, thus excluding the Lesotho mountain regions. It is home to some of the largest South African urban agglomerations . In Egypt are the Giza Plateau and Galala Mountain , which

The highest African plateau is the Ethiopian Highlands which cover the central part of Ethiopia. It forms the largest continuous area of its altitude in the continent, with little of its surface falling below 1,500 metres (4,921 ft), while the summits reach heights of up to 4,550 metres (14,928 ft).

In northern Arizona and southern Utah the Colorado Plateau is bisected by the Colorado River and the Grand Canyon . This came to be over 10 million years ago,
840-605: The Earth's crust following a massive volcanic eruption . The eruption event occurred during the end of the cretaceous period (66 mya ) and is the second largest volcanic eruption ever recorded on land. Scientists state that the volcanic event would have released large amounts of ash , dust and carbon dioxide into the atmosphere. The release would have blocked sunlight resulting in lower temperatures and caused major climatic changes on Earth. The eruption would have resulted in high levels of sulfur , chlorine and other toxic gases in

In 1880,

Underlying the lava deposits are granite and sedimentary rocks formed during

The Tibetan Plateau covers approximately 2,500,000 km (970,000 sq mi), at about 5,000 m (16,000 ft) above sea level. The plateau is sufficiently high to reverse the Hadley cell convection cycles and to drive the monsoons of India towards

The word Deccan is an anglicised version of the Prakrit word dakkhaṇa , which evolved from the Sanskrit word dakṣiṇa , meaning "south".

The Altiplano plateau hosts several cities like Puno, Oruro, El Alto and La Paz the administrative seat of Bolivia. Northeastern Altiplano is more humid than the Southwestern, the latter of which hosts several salares , or salt flats, due to its aridity. At the Bolivia-Peru border lies Lake Titicaca ,

1740-742: The crust. Tectonic plateaus are formed by tectonic plate movements which cause uplift, and are normally of a considerable size, and a fairly uniform altitude. Examples are the Deccan Plateau in India and the Meseta Central on the Iberian Peninsula . Plateaus can also be formed by the erosional processes of glaciers on mountain ranges, leaving them sitting between the mountain ranges. Water can also erode mountains and other landforms down into plateaus. Dissected plateaus are highly eroded plateaus cut by rivers and broken by deep narrow valleys. An example

The British Empire took control of the region from the British East India Company in 1857. During the British colonial rule , the region was divided between the Madras Presidency , Bombay Presidency , Hyderabad State , and Mysore . The region played

The region receives most of the rainfall during the months of July to September and the rains feed the rivers that flow into basins and then into the Bay of Bengal.

The region forms one of the major watersheds of India, with many perennial river systems such as Godavari , Krishna , and Kaveri flowing through
2460-442: The north-western United States is an example. They may be formed by upwelling of volcanic magma or extrusion of lava. The underlining mechanism in forming plateaus from upwelling starts when magma rises from the mantle , causing the ground to swell upward. In this way, large, flat areas of rock are uplifted to form a plateau. For plateaus formed by extrusion, the rock is built up from lava spreading outward from cracks and weak areas in
