Andaman Islands in the context of "Burma plate"

In biology, the canopy is the aboveground portion of a plant cropping or crop, formed by the collection of individual plant crowns. In forest ecology, the canopy is the upper layer or habitat zone, formed by mature tree crowns and including other biological organisms (epiphytes, lianas, arboreal animals, etc.). The communities that inhabit the canopy layer are thought to be involved in maintaining forest diversity, resilience, and functioning. Shade trees normally have a dense canopy that blocks light from lower growing plants.

Early observations of canopies were made from the ground using binoculars or by examining fallen material. Researchers would sometimes erroneously rely on extrapolation by using more reachable samples taken from the understory. In some cases, they would use unconventional methods such as chairs suspended on vines or hot-air dirigibles, among others. Modern technology, including adapted mountaineering gear, has made canopy observation significantly easier and more accurate, allowed for longer and more collaborative work, and broaddened the scope of canopy study.

The Andaman and Nicobar Islands is a union territory of India comprising 836 islands, of which only 31 are inhabited. The islands are grouped into two main clusters: the northern Andaman Islands and the southern Nicobar Islands, separated by a 150 km (93 mi) wide channel. The capital and largest city of the territory, Port Blair (officially Sri Vijaya Puram), is located approximately 1,190 km (740 mi) from Chennai and 1,255 km (780 mi) from Kolkata in mainland India. The islands are situated between the Bay of Bengal to the west and the Andaman Sea to the east. The northernmost point is 901 km (560 mi) from the mouth of the Hooghly River. Indira Point, located at 6°45'10″N and 93°49'36″E on the southern tip of Great Nicobar, is the southernmost point of India.

The territory shares maritime borders with Indonesia located about 165 km (103 mi) to the south, Myanmar located 280 km (170 mi) to the north-east and Thailand located 650 km (400 mi) to the south-east. The islands occupy a total land area of approximately 8,249 km (3,185 sq mi) with a population of 380,581 as per the 2011 census. The territory is divided into three districts: Nicobar, South Andaman, and North and Middle Andaman with the capitals at Car Nicobar, Port Blair and Mayabunder respectively.

Sumatra (/sʊˈmɑːtrə/) is one of the Sunda Islands of western Indonesia. It is the largest island that is fully within Indonesian territory, as well as the sixth-largest island in the world at 482,286.55 km (182,812 mi.), including adjacent islands such as the Simeulue, Nias, Mentawai, Enggano, Riau Islands, Bangka Belitung and Krakatoa archipelago.

Sumatra is an elongated landmass spanning a diagonal northwest–southeast axis. The Indian Ocean borders the northwest, west, and southwest coasts of Sumatra, with the island chain of Simeulue, Nias, Mentawai, and Enggano off the western coast. In the northeast, the narrow Strait of Malacca separates the island from the Malay Peninsula, which is an extension of the Eurasian continent. In the southeast, the narrow Sunda Strait, containing the Krakatoa archipelago, separates Sumatra from Java. The northern tip of Sumatra is near the Andaman Islands, while off the southeastern coast lie the islands of Bangka and Belitung, Karimata Strait and the Java Sea. The Bukit Barisan mountains, which contain several active volcanoes, form the backbone of the island, while the northeastern area contains large plains and lowlands with swamps, mangrove forest and complex river systems. The equator crosses the island at its centre in West Sumatra and Riau provinces. The climate of the island is tropical, hot, and humid. Lush tropical rain forest once dominated the landscape.

The Andaman Sea (historically also known as the Burma Sea) is a marginal sea of the northeastern Indian Ocean bounded by the coastlines of Myanmar and Thailand along the Gulf of Martaban and the west side of the Malay Peninsula, and separated from the Bay of Bengal to its west by the Andaman Islands and the Nicobar Islands. Its southern end is at Breueh Island just north of Sumatra, with the Strait of Malacca further southeast.

Traditionally, the sea has been used for fishery and transportation of goods between the coastal countries and its coral reefs and islands, which are popular tourist destinations. The fishery and tourist infrastructure was severely damaged by the December 2004 Indian Ocean earthquake and tsunami.

The Nicobar Islands /ˈnɪkəbɑːr/ are an archipelagic island chain in the eastern Indian Ocean. They are located in Southeast Asia, 150 kilometres (93 mi) northwest of Aceh on Sumatra, and separated from Thailand to the east by the Andaman Sea. Located 1,300 kilometres (810 mi) southeast of the Indian subcontinent, across the Bay of Bengal, they are part of India, as the Nicobar district within the union territory of the Andaman and Nicobar Islands. Together with the Andaman Islands to their north, the Nicobar Islands serve as a maritime boundary between the Bay of Bengal to the west and the Andaman Sea to the east.

In 2013, UNESCO added the Great Nicobar Island to its World Network of Biosphere Reserves, a list of internationally designated protected areas.

The Ten Degree Channel is a channel that separates the Andaman Islands and Nicobar Islands from each other in the Bay of Bengal. The two sets of islands together form the Indian Union Territory (UT) of Andaman and Nicobar Islands. This channel is 150 kilometres (93 mi) wide from north to south, and approximately 10 kilometres (6.2 mi) long from east to west. It has minimum depth of 7.3m and lies from east to west on the 10-degree line of latitude north of the equator, hence the name.
