West Tian Shan mountains. The Tian Shan is a mountain range in central Asia that extends through western China, Kazakhstan, and Kyrgyzstan. [1] The Tian Shan is 2,800 kilometres (1,700 mi) long, and up to 7,400 metres (24,300 ft) high. Throughout the Tian Shan there are several intermontane basins separated by high ranges. [1]
The Tian Shan are a mountain range north of the Tibetan Plateau and the Taklamakan Desert. Uplift of these mountains began 24 million years ago. It was a direct response to the continued extension of the Indian collision zone. The mountain range is still uplifting today along with the Himalaya. [9] [10]
Altogether, the glacial Tian Shan glaciation occupied an area of approximately 118,000 square kilometers. The glacier snowline was about 1200m lower during the last ice age than it is today. This would result in a depression of the average annual temperature of 7.2 to 8.4 °C for the Last Glacial Maximum compared with today, assuming a ...
Urumqi Glacier No.1 (Chinese: 乌鲁木齐1号冰川 or 乌鲁木齐一号冰川) or Urumqi River Glacier No.1 (Chinese: 乌鲁木齐河1号冰川 or 乌鲁木齐河一号冰川), Tianshan Glacier No.1 (Chinese: 天山1号冰川 or 天山一号冰川), is the glacier closest to an urban area in the world, located only 120 km southwest to downtown Ürümqi, Xinjiang, China. [1]
The Paleozoic rocks in the Tien Shan mountains are the remnants of accreted island arcs, mainly from the Ordovician onward. During the Vendian , the Northern Turkestan domain was part of the Kipchak island arc system between the East European and Siberian continent, separated by the Terksey back-arc basin which had originated as a rift basin.
The ecoregion stretches around the lower altitudes of the Tian Shan mountain ridge, running for approximately 2,000 km from western Kyrgyzstan to eastern Xinjiang Province in China. [1] It separates the arid Tarim Basin and Taklimakan Desert to the south from the Junggar Basin and Kazakh Shield to the north.
The Tian Shan foothill arid steppe ecoregion (WWF ID: PA0818) covers the northern and western approaches to the Tian Shan mountains, centered on Lake Issyk-Kul in Kyrgyzstan. This region receives more moisture from Central Asia, thereby supporting more vegetation and diversity of plant and animal species than the deserts to the south.
Franz Josef Glacier in New Zealand Features of a glacial landscape. Glacier morphology, or the form a glacier takes, is influenced by temperature, precipitation, topography, and other factors. [1] The goal of glacial morphology is to gain a better understanding of glaciated landscapes and the way they are shaped. [2]
