Aravalli Range

The Aravali Range (हिन्दी, संस्कृत= अरावली) literally meaning 'line of peaks', is a range of mountains in western India running approximately 692 km in a northeastern direction across Indian states of Gujarat, Rajasthan, Haryana and punjab.

Features

The Aravalli range are the oldest Plateau mountains in India. The northern end of the range continues as isolated hills and rocky ridges into Haryana state, ending in Delhi. The famous Delhi Ridge is the last leg of the Aravalli Range, which traverses through South Delhi and terminates into Central Delhi where Raisina hill is its last extension. It is one of the world's oldest mountain ranges. It dates back to a pre-Indian subcontinental collision with the mainland Eurasian Plate. The southern end is at Palanpur near Ahmedabad, Gujarat. The highest peak is Guru Shikhar in Mount Abu in Rajasthan. Rising to 5650 feet (1722 meters), it lies near the south-western extremity of the range, close to the border with Gujarat state. The city of Udaipur with its lakes lies on the south slope of the range in Rajasthan. Numerous rivers rise amidst the ranges including the Banas River, the Luni River, the Sahibi, the Sakhi, and the Sabarmati River.The Aravalli Range is the eroded stub of a range of ancient folded mountains. The range rose in a Precambrian event called the Aravalli-Delhi orogen. The range joins two of the ancient segments that make up the Indian craton, the Marwar segment to the northwest of the range, and the Bundelkhand segment to the southeast. Old fold mountains are characterized by having stopped growing higher due to the cessation of upward thrust caused by the stopping of movement of the tectonic plates in the Earth's crust below them. In ancient times they were extremely high but since have worn down almost completely by millions of years of weathering. In contrast, the Himalayas are continuously rising young fold mountains of today.

South Asia

South Asia or Southern Asia is a term used to represent the southern region of the Asian continent, which comprises the sub-Himalayan SAARC countries and, for some authorities, adjoining countries to the west and east. Topographically, it is dominated by the Indian Plate, which rises above sea level as Nepal and northern parts of India situated south of the Himalayas and the Hindu Kush. South Asia is bounded on the south by the Indian Ocean and on land (clockwise, from west) by West Asia, Central Asia, East Asia, and Southeast Asia. The terms "Indian subcontinent" and "South Asia" are sometimes used interchangeably.

The current territories of Afghanistan, Bangladesh, Bhutan, Maldives, Nepal, India, Pakistan, and Sri Lanka form the countries of South Asia. In addition, with deviating definitions based on often substantially different reasons, the British Indian Ocean Territory, Mauritius, and the Tibet Autonomous Region are included as well. South Asia is home to well over one fifth of the world's population, making it both the most populous and the most densely populated geographical region in the world. The South Asian Association for Regional Cooperation(SAARC) is an economic cooperation organisation in the region which was established in 1985 and includes all eight nations comprising South Asia.

Delhi

Delhi (/ˈdɛli/, Hindustani pronunciation: [d̪ɪlliː] Dilli), officially the National Capital Territory of Delhi, is the capital territory of India. Delhi is historically and culturally connected to both the Upper Doab of the Yamuna-Ganges river system and the Punjab region. It is bordered by Haryana on three sides and by Uttar Pradesh to the east. It is the largest city in India in terms of geographical area - about 1,484 square kilometres (573 sq mi). It has a population of about 16.3 million, making it the second most populous city and second most populous urban agglomeration in India and 3^rd largest urban area in the world. Such is the nature of urban expansion in Delhi that its growth has expanded beyond the NCT to incorporate towns in neighbouring states and at its largest extent can count a population of about 25 million residents as of 2014.

Delhi has been continuously inhabited since the 6th century BC. Through most of its history, Delhi has served as a capital of various kingdoms and empires. It has been captured, ransacked and rebuilt several times, particularly during the medieval period, and modern Delhi is a cluster of a number of cities spread across the metropolitan region.
