Question 1

Which of the following is the longest river in the world by total length?

Accepted Answer

The Nile River in Africa is the longest river in the world with a total length of approximately 6,650 km. It flows through eleven countries and is a critical water source for Egypt and Sudan. The Amazon is the largest by discharge volume but not by length.

Question 2

Which of the following is the longest river in Africa by total length?

Accepted Answer

The Nile River is the longest river in Africa, with a total length of approximately 6,650 kilometers. It flows through eleven countries and is a critical water source for Egypt and Sudan. The Congo River, while the second-longest in Africa at about 4,700 km, is sometimes confused due to its massive discharge volume. The Zambezi and Niger are significant African rivers but are considerably shorter than the Nile.

Question 3

Mount Kilimanjaro, the highest peak in Africa, is located in which country?

Accepted Answer

Mount Kilimanjaro is located in Tanzania, East Africa. It stands at 5,895 meters above sea level and is a dormant volcano. While Kilimanjaro is near the Kenya-Tanzania border, the mountain itself lies entirely within Tanzanian territory. Kenya is home to Mount Kenya (5,199 m), which is Africa's second-highest peak, a common source of confusion.

Question 4

The Strait of Malacca, one of the world's most strategically important waterways, separates which two landmasses?

Accepted Answer

The Strait of Malacca separates the Malay Peninsula (part of Malaysia) from the island of Sumatra (part of Indonesia). This narrow waterway, approximately 900 kilometers long and at its narrowest point only 2.7 kilometers wide, connects the Andaman Sea to the South China Sea. It is one of the world's busiest shipping routes, with approximately one-third of global maritime trade passing through it. The Strait of Singapore, while nearby, is a different waterway that separates Singapore from Indonesia.

Question 5

The Atacama Desert, one of the driest places on Earth, is located in which South American country?

Accepted Answer

The Atacama Desert is located in Chile, stretching along the western coast of South America for approximately 1,600 kilometers. It is one of the driest non-polar deserts in the world, with some regions receiving virtually no rainfall in recorded history. The desert also extends into small portions of Peru, Bolivia, and Argentina, but the majority of it lies within Chilean territory. The Kalahari Desert is in southern Africa, not South America, making it a clear distractor.

Question 6

The Dead Sea, the lowest point on Earth's land surface, is bordered by which two countries?

Accepted Answer

The Dead Sea is bordered by Israel and Jordan. It lies at approximately 430 meters below sea level, making it the lowest point on Earth's land surface. The West Bank also borders the Dead Sea, but it is not an independent country. The Dead Sea is a hypersaline lake with a salt concentration of approximately 34.2%, making it one of the saltiest bodies of water on Earth. The Mediterranean Sea, while nearby, is a different body of water entirely.

Question 7

Which of the following straits separates the island of New Guinea from Australia?

Accepted Answer

The Torres Strait is the body of water that separates Papua New Guinea (the eastern half of New Guinea island) from Australia. It is approximately 150 km wide at its narrowest point and connects the Coral Sea to the east with the Arafura Sea to the west. This strait is a critical maritime passage in the Indo-Pacific region.

Question 8

The Gobi Desert, one of the largest deserts in Asia, is primarily located in which two countries?

Accepted Answer

The Gobi Desert is primarily located in Mongolia and China. It covers an area of approximately 1.3 million square kilometers and is the second-largest desert in Asia. The desert spans across southern Mongolia and northern China (primarily in Inner Mongolia, Gansu, and Ningxia provinces). The Gobi is characterized by its cold winters and sparse vegetation, and it has been historically significant as part of the Silk Road.

Question 9

The Amazon River, the world's largest river by water discharge, flows through how many South American countries?

Accepted Answer

The Amazon River flows through 9 South American countries: Peru, Colombia, Venezuela, Ecuador, Brazil, Bolivia, Guyana, Suriname, and French Guiana (an overseas territory of France). However, for standard competitive exam purposes, the answer typically counts sovereign nations, which would be 8 countries (excluding French Guiana as it is not an independent nation). The most common and accepted answer in Indian competitive exams is 9 if including French Guiana, or 8 if counting only independent nations. The safest answer for NDA is 9 countries, as most geography texts list all territories through which the Amazon basin extends.

Question 10

Which of the following straits separates the island of Borneo from the Philippines?

Accepted Answer

The Celebes Sea is bounded by several straits. The strait that directly separates Borneo from the Philippines is the Celebes Strait (also called Makassar Strait in some contexts, but more precisely, the waterway between them is referenced as part of the Sulu Sea and Celebes Sea system). However, the most accurate answer is that the Basilan Strait and Mindanao Strait separate the southern Philippines from Borneo. The primary strait commonly referenced in geography texts for this separation is the Celebes Strait. For NDA-level precision: the Sulu Strait separates Mindanao (Philippines) from Sabah (Malaysian Borneo), while the Celebes Strait lies to the east. The correct answer is the Sulu Strait, which is the most direct and commonly cited strait in standard geography curricula.

Question 11

The Atacama Desert, one of the driest places on Earth, is located in which South American country or countries?

Accepted Answer

The Atacama Desert spans across northern Chile and extends into southern Peru and northwestern Argentina. It is the driest non-polar desert in the world, with some weather stations recording no rainfall for over 400 years. The desert is primarily located in Chile, covering approximately 1,600 km along the Pacific coast.

Question 12

Which strait separates the island of New Guinea from Australia, and what is its approximate width?

Accepted Answer

The Torres Strait separates Papua New Guinea (the eastern half of New Guinea) from Australia's northernmost point (Cape York Peninsula). The strait is approximately 150 km (93 miles) wide at its narrowest point. It connects the Coral Sea to the east with the Arafura Sea to the west.

Question 13

The Danube River, Europe's second-longest river, flows through how many countries before emptying into the Black Sea?

Accepted Answer

The Danube River flows through 10 countries: Germany, Austria, Slovakia, Hungary, Serbia, Romania, Bulgaria, Moldova, Ukraine, and the Danube Delta region. However, it empties into the Black Sea via the Danube Delta in Romania. The river is approximately 2,857 km long and is the second-longest river in Europe after the Volga.

Question 14

Mount Kilimanjaro, Africa's highest peak, is located in which country and at what elevation?

Accepted Answer

Mount Kilimanjaro is located in Tanzania (northeastern region near the Kenya border) and stands at 5,895 meters (19,341 feet) above sea level. It is the highest mountain in Africa and the highest free-standing mountain in the world. The mountain has three volcanic cones: Kibo, Mawenzi, and Shira.

Question 15

The Amazon River, the world's largest river by discharge volume, flows through how many countries, and which country contains the largest portion of the Amazon Basin?

Accepted Answer

The Amazon River flows through 9 countries: Brazil, Peru, Colombia, Venezuela, Ecuador, Bolivia, Guyana, Suriname, and French Guiana. Brazil contains approximately 60% of the Amazon Basin and the river's mouth. The Amazon discharges approximately 209,000 cubic meters of water per second into the Atlantic Ocean, accounting for about 20% of all river water that flows into the world's oceans.

Question 16

The Atacama Desert, one of the driest places on Earth, is located in which South American country/countries?

Accepted Answer

The Atacama Desert is primarily located in Chile, stretching along the Pacific coast for approximately 1,600 km. While small portions extend into Peru and Bolivia, the vast majority (over 95%) of the Atacama Desert lies within Chilean territory, specifically in the northern regions of Chile. For competitive exam purposes, the standard answer is Chile.

Question 17

Mount Kilimanjaro, Africa's highest peak, is located in which country?

Accepted Answer

Mount Kilimanjaro is located in Tanzania, East Africa. It stands at 5,895 meters (19,341 feet) above sea level and is the highest mountain in Africa. While Kilimanjaro is near the Kenya-Tanzania border, the mountain itself lies entirely within Tanzanian territory. It is a dormant volcano with three volcanic cones: Kibo, Mawenzi, and Shira.
