Question: Information: - The Sittaung ( Burmese : ( s ta mj ) ; formerly , the Sittang or Sittoung ) is a river in south central Myanmar in Bago Division . The Pegu Range separates its basin from that of the Irrawaddy . The river originates at the edge of the Shan Plateau southeast of Mandalay , and flows southward to the Gulf of Martaban . Its length is 420 km and its mean annual discharge is around 50 cubic kilometers per year . - Mount Popa is a volcano 1518 metres (4981feet) above sea level, and located in central Burma (Myanmar) about southeast of Bagan (Pagan) in the Pegu Range. It can be seen from the Ayeyarwady (Irrawaddy) River as far away as in clear weather. Mount Popa is perhaps best known as a pilgrimage site, with numerous Nat temples and relic sites atop the mountain. - Bangladesh ( , "The country of Bengal"), officially the People's Republic of Bangladesh ( "Gonoprojatontri Bangladesh"), is a country in South Asia. It shares land borders with India and Myanmar (Burma). Nepal, Bhutan and China are located near Bangladesh but do not share a border with it. The country's maritime territory in the Bay of Bengal is roughly equal to the size of its land area. Bangladesh is the world's eighth most populous country. Dhaka is its capital and largest city, followed by Chittagong which has the country's largest port. - Myanmar, officially the Republic of the Union of Myanmar and also known as Burma, is a sovereign state in South East Asia bordered by Bangladesh, India, China, Laos and Thailand. About one third of Myanmar's total perimeter of 5,876km (3,651 miles), forms an uninterrupted coastline of 1,930km (1,200 miles) along the Bay of Bengal and the Andaman Sea. The country's 2014 census revealed a much lower population than expected, with 51 million people recorded. Myanmar is 676,578squarekilometres (261,227sqmi) in size. Its capital city is Naypyidaw and its largest city is Yangon (Rangoon). - An ocean (the sea of classical antiquity) is a body of saline water that composes much of a planet's hydrosphere. On Earth, an ocean is one of the major conventional divisions of the World Ocean, which covers almost 71% of its surface. These are, in descending order by area, the Pacific, Atlantic, Indian, Southern (Antarctic), and Arctic Oceans. The word "sea" is often used interchangeably with "ocean" in American English but, strictly speaking, a sea is a body of saline water (generally a division of the world ocean) partly or fully enclosed by land. - The Irrawaddy River or Ayeyarwady River (, also spelt Ayeyarwaddy) is a river that flows from north to south through Myanmar. It is the country's largest river and most important commercial waterway. Originating from the confluence of the N'mai and Mali rivers, it flows relatively straight North-South before emptying through the Irrawaddy Delta into the Andaman Sea. Its drainage basin of about covers a large part of Burma. After Rudyard Kipling's poem, it is sometimes referred to as 'The Road to Mandalay'. - The Bay of Bengal, the largest bay in the world, forms the northeastern part of the Indian Ocean. Roughly triangular, it is bordered mostly by India and Sri Lanka to the west, Bangladesh to the north, and Myanmar (Burma) and the Andaman and Nicobar Islands (India) to the east. - A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as stream, creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. - India, officially the Republic of India ("Bhrat Gaarjya"), is a country in South Asia. It is the seventh-largest country by area, the second-most populous country (with over 1.2 billion people), and the most populous democracy in the world. It is bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast. It shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the northeast; and Myanmar (Burma) and Bangladesh to the east. In the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives. India's Andaman and Nicobar Islands share a maritime border with Thailand and Indonesia. Its capital is New Delhi; other metropolises include Mumbai, Kolkata, Chennai, Bangalore, Hyderabad and Ahmedabad. - Mandalay is the second-largest city and the last royal capital of Myanmar (Burma). Located north of Yangon on the east bank of the Irrawaddy River, the city has a population of 1,225,553 (2014 census). - The Pegu Range (Pegu Yoma or Bago Yoma) is a range of low mountains or hills and uplands between the Irrawaddy and the Sittaung River in central Burma (Myanmar). The range runs from Mount Popa in the north to Singguttara Hill (Theingottara Hill) in the south. Both the Pegu River and the Sittaung River originate in the Pegu Range. - A sea is a large body of salt water that is surrounded in whole or in part by land. More broadly, "the sea" is the interconnected system of Earth's salty, oceanic watersconsidered as one global ocean or as several principal oceanic divisions. The sea moderates Earth's climate and has important roles in the water cycle, carbon cycle, and nitrogen cycle. Although the sea has been traveled and explored since prehistory, the modern scientific study of the seaoceanographydates broadly to the British "Challenger" expedition of the 1870s. The sea is conventionally divided into up to five large oceanic sectionsincluding the International Hydrographic Organization's four named oceans (the Atlantic, Pacific, Indian, and Arctic) and the Southern Ocean; smaller, second-order sections, such as the Mediterranean, are known as "seas". - The Gulf of Martaban is an arm of the Andaman Sea in the southern part of Burma. The gulf is named after the port city of Mottama (formerly known as Martaban). The Salween Sittaung and Yangon rivers empty into it. - The Andaman Sea is a body of water to the southeast of the Bay of Bengal, south of Myanmar (Burma), west of Thailand, north-west of Malay Peninsula, north of Sumatra and east of the Andaman Islands, India, from which it takes its name; it is part of the Indian Ocean. Given the information, choose the subject and object entities that have the relation of 'mouth of the watercourse'.
