25-742: The Garhjat Hills is a mountain range formed by a series low-lying hills, plateaux , ridges and meadows that stretch into Odisha from the Utkal Plains in the Chotanagpur region of Jharkhand and the Chhattisgarh Plains. The range, also known as the Odisha Highlands, runs in a north east to south west direction for about 382 km along the Odisha coast, covering 76,800 km (29,700 sq mi). The range rises abruptly and steeply in

50-402: A mountainous region, elevated mountainous plateau or high hills . Generally, upland refers to a range of hills, typically from 300 m (980 ft) up to 600 m (2,000 ft), while highland is usually reserved for ranges of low mountains . However, the two terms are interchangeable and also include regions that are transitional between hilly and mountainous terrain. Probably

75-525: Is at work while the mountains are being uplifted until the mountains are reduced to low hills and plains. The early Cenozoic uplift of the Rocky Mountains of Colorado provides an example. As the uplift was occurring some 10,000 feet (3,000 m) of mostly Mesozoic sedimentary strata were removed by erosion over the core of the mountain range and spread as sand and clays across the Great Plains to

100-592: Is the Central Highlands area, which covers most of the central-western parts of the state. Many of these areas are highly elevated alpine regions. The Ozarks cover nearly 120,000 square kilometres (46,000 sq mi), making it the most extensive highland region between the Appalachians and Rockies. This region contains some of the oldest rocks in North America. The spine of the mountains stretches across

125-823: The Alpide belt . The Pacific Ring of Fire includes the Andes of South America, extends through the North American Cordillera , the Aleutian Range , on through Kamchatka Peninsula , Japan , Taiwan , the Philippines , Papua New Guinea , to New Zealand . The Andes is 7,000 kilometres (4,350 mi) long and is often considered the world's longest mountain system. The Alpide belt stretches 15,000 km across southern Eurasia , from Java in Maritime Southeast Asia to

150-538: The Annamite Range . If the definition of a mountain range is stretched to include underwater mountains, then the Ocean Ridge forms the longest continuous mountain system on Earth, with a length of 65,000 kilometres (40,400 mi). The position of mountain ranges influences climate, such as rain or snow. When air masses move up and over mountains, the air cools, producing orographic precipitation (rain or snow). As

175-841: The Eastern Ghats . It derives its name from the Hindi term for ' fort ', garh . The region was named by the Mughals who conquered Odisha under Akbar . Under the Marathas too Odisha was divided into the Mughalbandhi and Garhjat provinces and the latter was ruled by 24 vassal chiefs who paid tribute to the Marathas. These states, the Orissa Tributary States , later came to be known as the Garhjat states or

200-678: The Garhjats because they were located in the region of the range. These hills cover the present day districts of Sundargarh , Sambalpur , Deogarh , Jharsuguda , Baragarh , Angul and Kendujhar in northern Odisha. Rourkela in Sundargarh district is a major industrial town. The Garhjat hills are bounded by the Chotanagpur Plateau in the north, the Utkal plains in the east, the Mahanadi basin or

225-772: The Iberian Peninsula in Western Europe , including the ranges of the Himalayas , Karakoram , Hindu Kush , Alborz , Caucasus , and the Alps . The Himalayas contain the highest mountains in the world, including Mount Everest , which is 8,848 metres (29,029 ft) high. Mountain ranges outside these two systems include the Arctic Cordillera , Appalachians , Great Dividing Range , East Siberians , Altais , Scandinavians , Qinling , Western Ghats , Vindhyas , Byrrangas , and

250-594: The Mithrim Montes and Doom Mons on Titan, and Tenzing Montes and Hillary Montes on Pluto. Some terrestrial planets other than Earth also exhibit rocky mountain ranges, such as Maxwell Montes on Venus taller than any on Earth and Tartarus Montes on Mars . Jupiter's moon Io has mountain ranges formed from tectonic processes including the Boösaule , Dorian, Hi'iaka and Euboea Montes . Highland Highlands or uplands are areas of high elevation such as

275-638: The United States (notably Western North Carolina ), highveld , used in South Africa and Roof of the World , used for Tibet . The central Afghan highlands are in the center of Afghanistan , mostly located between 2,000 and 3,000 m above sea level. They have a very cold winter, and a short and cool summer. These highlands have mountain pastures during summer ( sardsīr ), watered by many small streams and rivers. There are also pastures available during winter in

300-672: The Chhattisgarh plains in the west and the Eastern Ghats to the south. Geologically, the region comprises crystalline rocks such as granites and gneisses that belong to the Archaean period . The Talcher , Barakar and Kamathi series of rocks containing shales and sandstones occur in the Sambalpur and Dhei districts. The northern Garhjat hills are a part of the Chotanagpur plateau while

325-1083: The United Kingdom include the Southern Uplands in Scotland, the Pennines , North York Moors , Dartmoor and Exmoor in England , and the Cambrian Mountains in Wales . Many countries and regions also have areas referred to as highlands . These include parts of Afghanistan , Tibet , Ethiopia , Canada , Kenya , Eritrea , Yemen , Ghana , Nigeria , Papua New Guinea , Syria , Turkey and Cantabria . Similar terms used in other countries include high country , used in New Zealand , New South Wales , Victoria , Tasmania and Southern Queensland in Australia , and parts of

350-623: The air descends on the leeward side, it warms again (following the adiabatic lapse rate ) and is drier, having been stripped of much of its moisture. Often, a rain shadow will affect the leeward side of a range. As a consequence, large mountain ranges, such as the Andes, compartmentalize continents into distinct climate regions . Mountain ranges are constantly subjected to erosional forces which work to tear them down. The basins adjacent to an eroding mountain range are then filled with sediments that are buried and turned into sedimentary rock . Erosion

375-646: The best-known area officially or unofficially referred to as highlands in the Anglosphere is the Scottish Highlands in northern Scotland , the mountainous region north and west of the Highland Boundary Fault . The Highland council area is a local government area in the Scottish Highlands and Britain's largest local government area. Other highland or upland areas reaching 400 m or higher in

400-478: The east and slopes gently to a dissected plateau in the west running from north-east ( Mayurbhanj ) to south-west ( Malkangiri ). The whole area is also marked by intermontane basins which cut across the region in a number of broad and narrow river valleys and flood plains. The average height of the range is about 900 metres above mean sea level. Geographically the Garhjat Range is a northward prolongation of

425-485: The east. This mass of rock was removed as the range was actively undergoing uplift. The removal of such a mass from the core of the range most likely caused further uplift as the region adjusted isostatically in response to the removed weight. Rivers are traditionally believed to be the principal cause of mountain range erosion, by cutting into bedrock and transporting sediment. Computer simulation has shown that as mountain belts change from tectonically active to inactive,

450-629: The endemic vertebrates are restricted to this ecoregion. The highlands of Iceland cover about 40% of the country and are mostly inhospitable to humans. They are generally considered to be any land above 500 m. The mountainous natural region of the Thai highlands is found in Northern Thailand. The Cameron Highlands is a highland area and hill station in Northern Malaysia. Shillong in India in

475-593: The island of New Guinea, forming the densely populated highlands of Papua New Guinea , and the Highland Papua , Indonesia . The Central Highlands of Sri Lanka are rain forests, where the elevation reaches 2,500 m (8,200 ft) above sea level. The Sri Lanka montane rain forests represent the montane and submontane moist forests above 1,000 m (3,300 ft) in the central highlands and in the Knuckles mountain range . Half of Sri Lanka's endemic flowering plants and 51 percent of

500-563: The neighboring warm lowlands ( garmsīr ), which makes the region ideal for seasonal transhumance . The highlands in Australia are often above the elevation of 500 m. These areas often receive snowfall in winter. Most of the highlands lead up to large alpine or sub-alpine mountainous regions such as the Australian Alps , Snowy Mountains , Great Dividing Range , Northern Tablelands and Blue Mountains . The most mountainous region of Tasmania

525-617: The rate of erosion drops because there are fewer abrasive particles in the water and fewer landslides. Mountains on other planets and natural satellites of the Solar System, including the Moon , are often isolated and formed mainly by processes such as impacts, though there are examples of mountain ranges (or "Montes") somewhat similar to those on Earth. Saturn 's moon Titan and Pluto , in particular, exhibit large mountain ranges in chains composed mainly of ices rather than rock. Examples include

550-817: The region's population and the Gonds are a major tribal group of this region. Malaria is a major public health concern in these hills. Some of the important peaks of the Garhjat Hills include the Malayagiri , Manakamacha and Meghasani . The Mahanadi river bisects these hills and to its south, the hills tend to gain elevation. The highest peak to the south is the Mahendragiri in Gajapati district . Mountain range Mountain ranges are usually segmented by highlands or mountain passes and valleys . Individual mountains within

575-521: The same mountain range do not necessarily have the same geologic structure or petrology . They may be a mix of different orogenic expressions and terranes , for example thrust sheets , uplifted blocks , fold mountains, and volcanic landforms resulting in a variety of rock types . Most geologically young mountain ranges on the Earth's land surface are associated with either the Pacific Ring of Fire or

600-617: The southern part is an extension of the Eastern Ghats and can be divided into three - the northern uplands, the Mahanadi valley, and the south-western hills. The important rivers that drain the Garhjat hills are the Brahmani , the Mahanadi , the Baitarani and the Subarnarekha . The Odisha Highlands are densely forested with tropical semi-evergreen and tropical dry and moist deciduous forests . The Scheduled Tribes account for as much as 37% of

625-525: The state of Meghalaya is a hill station that is surrounded by highlands. Officers of the British Raj referred to Shillong as "The Scotland of the East". Highland continents —or terrae —are areas of topographically unstable terrain , with high peaks and valleys. They resemble highlands on Earth , but the term is applied to much larger areas on other planets. They can be found on Mercury , Venus , Mars , and
