Ships from which of the following countries have to cross the Strait of Hormuz to reach out to the Indian Ocean?

  1. 1.Bahrain
  2. 2.Syria
  3. 3.Qatar
  4. 4.Egypt

Select the answer using the code given below:

Answer & explanation

Answer: (b) 1 and 3

The Strait of Hormuz, between Iran and Oman, is the only sea exit from the Persian Gulf to the Gulf of Oman and the Arabian Sea. Bahrain and Qatar have coasts only on the Persian Gulf, so their ships must pass through it. Syria and Egypt lie on the Mediterranean (and Egypt also on the Red Sea), so they reach the Indian Ocean via Suez and Bab-el-Mandeb instead.

  • ✓ 1. Bahrain is an island state inside the Persian Gulf, so every voyage to the Indian Ocean passes through Hormuz.
  • ✗ 2. Syria's coast is on the Mediterranean; its ships reach the Indian Ocean through the Suez Canal and the Red Sea.
  • ✓ 3. Qatar is a peninsula on the western shore of the Persian Gulf; its LNG and oil exports leave through Hormuz.
  • ✗ 4. Egypt has Mediterranean and Red Sea coasts, so its ships sail down the Red Sea and out through Bab-el-Mandeb.

Remember · Persian Gulf states needing Hormuz: Iraq, Kuwait, Bahrain, Qatar (plus most of Saudi, UAE and Iranian ports). Red Sea exit = Bab-el-Mandeb.

  2. 2.The lake is situated in South Sudan along the eastern fringe of the Sahara desert.
  3. 3.The lake is listed as a UNESCO World Heritage Site and is also referred to as the ‘Jade Sea’.

Select the answer using the code given below:

Answer & explanation

Answer: (b) 1 and 3 only

Lake Turkana is the world's largest desert lake and a UNESCO World Heritage property nicknamed the Jade Sea for its colour. It lies in the Rift Valley of northern Kenya, reaching up to the Ethiopian border, not in South Sudan.

  • ✓ 1. UNESCO describes Lake Turkana as the largest desert lake in the world and the most saline lake in East Africa.
  • ✗ 2. The lake is in Kenya, in the Rift Valley, and extends north to the Ethiopian border. South Sudan is not involved, and it is not a Sahara-fringe lake.
  • ✓ 3. Lake Turkana National Parks, in Kenya, were inscribed on the World Heritage List in 1997. UNESCO notes the lake is fondly called the Jade Sea because of its colour.

Remember · Lake Turkana (Kenya, Rift Valley, to the Ethiopian border): largest desert lake in the world; Lake Turkana National Parks inscribed by UNESCO in 1997; called the Jade Sea.

Sources

  • UNESCO World Heritage Centre: Lake Turkana National Parks ↗ “The Lake is the most saline lake in East Africa and the largest desert lake in the world, surrounded by an arid, seemingly extraterrestrial landscape that is often devoid of life. … The long body of Lake Turkana drops down along the Rift Valley from the Ethiopian border, extending 249 kilometers from north to south and 44 km at its widest point with a depth of 30 meters. … It is Africa's fourth largest lake, fondly called the Jade Sea because of its breathtaking color. … The property is co-managed by Kenya Wildlife Service (KWS) and the National Museums of Kenya (NMK).”

Consider the following statements about river bridges connecting India with neighbouring countries:

  1. 1.‘Maitri Setu’, built over Feni river, connects Ramgarh in India with Sabroom in Bangladesh.
  2. 2.Jhulaghat suspension bridge connects India with Myanmar.
  3. 3.Mechi bridge and its approaches connect Panitanki Bypass in India with Kakarvitta in Nepal.

Which of the statements given above is/are correct?

Answer & explanation

Answer: (d) 3 only

Only statement 3 is right. Maitri Setu joins Sabroom in Tripura (India) with Ramgarh (Bangladesh), the reverse of what statement 1 says. The Jhulaghat bridge on the Kali river leads into Nepal, not Myanmar.

  • ✗ 1. Sabroom lies in South Tripura, India, and Ramgarh is on the Bangladesh side; the statement swaps the two countries.
  • ✗ 2. Jhulaghat is a town on the Indo-Nepal border named after a hanging bridge on the Kali river, through which one enters Nepal.
  • ✓ 3. The Mechi bridge is part of the upgraded Kakarvitta (Nepal) to Panitanki Bypass (India) road on NH 327B, and is the end point of Asian Highway 02 in India.

Remember · Maitri Setu: Sabroom (Tripura, India) – Ramgarh (Bangladesh) over the Feni. Jhulaghat (Pithoragarh) and the Mechi bridge (Panitanki–Kakarvitta) both lead into Nepal.
