Rivers and Mountains Quiz
From the Nile to K2: can you place the planet's greatest rivers and peaks?
What is the longest river in the world?
Got a hunch? Pick the answer that feels right.
Nile
The Nile runs about 6,650 km (4,130 miles) from the highlands around Lake Victoria to the Mediterranean, and most atlases still rank it first.
Brazilian researchers argue the Amazon is longer if measured from a remote Andean source, so the title remains contested.
Mount Everest is located on the border of which two countries?
Got a hunch? Pick the answer that feels right.
Nepal and China (Tibet)
Everest's summit sits on the border between Nepal and China's Tibet Autonomous Region, at 8,849 meters (29,032 feet) by the 2020 joint survey.
Nepalis call the mountain Sagarmatha and Tibetans call it Chomolungma; the English name honors surveyor George Everest, who never saw it.
Which river flows through 10 countries, more than any other river in the world?
Got a hunch? Pick the answer that feels right.
Danube
The Danube crosses 10 countries, from Germany and Austria in the west to Romania and Ukraine at its Black Sea delta, about 2,850 km in all.
It rises in Germany's Black Forest at Donaueschingen and is the only major European river that flows from west to east.
What is the tallest mountain in Africa?
Got a hunch? Pick the answer that feels right.
Mount Kilimanjaro
Kilimanjaro's Uhuru Peak stands 5,895 meters (19,341 feet) above sea level in Tanzania, and it is a free-standing volcano rather than part of a range.
Around 30,000 people attempt the climb each year, and no technical mountaineering skill is needed on the popular Marangu and Machame routes.
The Amazon River empties into which body of water?
Got a hunch? Pick the answer that feels right.
Atlantic Ocean
The Amazon reaches the Atlantic near Belem in Brazil through a mouth so wide that its freshwater plume can be traced more than 100 miles offshore.
There is no bridge across the Amazon along its entire length; the river is too wide and the surrounding land too sparsely populated to justify one.
Which mountain range separates Europe from Asia?
Got a hunch? Pick the answer that feels right.
Ural Mountains
The Urals run roughly 2,500 km from the Arctic coast to Kazakhstan and have marked the conventional boundary between Europe and Asia since the 18th century.
The range is one of the oldest on Earth, formed about 300 million years ago, which is why its highest point, Mount Narodnaya, is under 1,900 meters.
What is the largest river by volume of water discharge?
Got a hunch? Pick the answer that feels right.
Amazon
The Amazon discharges about 209,000 cubic meters of water per second, roughly a fifth of all the river water that reaches the world's oceans.
The Congo comes a distant second at around 41,000 cubic meters per second, still nearly 15 times the flow of the Nile.
K2, the second tallest mountain, is in which range?
Got a hunch? Pick the answer that feels right.
Karakoram
K2 rises 8,611 meters (28,251 feet) on the border of Pakistan and China in the Karakoram, a range separate from the Himalayas to its southeast.
K2 was not climbed in winter until a Nepali team summited in January 2021, and historically about one climber has died for every four who reached the top.
Through which capital city does the Danube River NOT flow?
Got a hunch? Pick the answer that feels right.
Prague
Prague sits on the Vltava, a tributary of the Elbe that flows north to the North Sea, well away from the Danube's course.
The Danube is the only river to pass through four national capitals: Vienna, Bratislava, Budapest and Belgrade.
What is the tallest mountain in North America?
Got a hunch? Pick the answer that feels right.
Denali (Mount McKinley)
Denali tops out at 6,190 meters (20,310 feet) in Alaska, and its rise of about 5,500 meters from base to summit is greater than Everest's.
The US federal government restored the name Mount McKinley in January 2025, while Alaska continues to use Denali, the Koyukon name meaning the high one.
The Yangtze River flows through which country?
Got a hunch? Pick the answer that feels right.
China
The Yangtze flows 6,300 km entirely within China, from the Tibetan Plateau to the East China Sea at Shanghai, making it Asia's longest river.
The Three Gorges Dam on the Yangtze is the world's largest power station by installed capacity, at 22,500 megawatts.
The Andes mountain range runs along the western coast of which continent?
Got a hunch? Pick the answer that feels right.
South America
The Andes stretch about 7,000 km through seven countries from Venezuela to Chile and Argentina, the longest continental mountain range on Earth.
Aconcagua in Argentina, at 6,961 meters, is the highest peak outside Asia and the highest in both the Western and Southern Hemispheres.
Which river is considered sacred in Hinduism?
Got a hunch? Pick the answer that feels right.
Ganges
Hindus revere the Ganges as the goddess Ganga, and bathing in it at Varanasi or Haridwar is believed to wash away a lifetime of sins.
The 2019 Kumbh Mela at Prayagraj, where the Ganges meets the Yamuna, drew an estimated 200 million pilgrims over seven weeks.
What is the highest mountain in Europe?
Got a hunch? Pick the answer that feels right.
Mount Elbrus
Mount Elbrus, a dormant volcano in Russia's Caucasus range, reaches 5,642 meters, well above Mont Blanc's 4,808 meters in the Alps.
Because some definitions put the Caucasus in Asia, Mont Blanc is sometimes cited as Europe's highest, but the Seven Summits lists all use Elbrus.
The Mississippi River empties into which body of water?
Got a hunch? Pick the answer that feels right.
Gulf of Mexico
The Mississippi ends in a bird's-foot delta below New Orleans, releasing its water into the Gulf of Mexico about 3,730 km from its source at Lake Itasca.
The US government renamed the gulf the Gulf of America on federal maps in 2025, though the name Gulf of Mexico remains standard internationally.

Is the Nile or the Amazon the longest river?
Most references list the Nile at about 6,650 km (4,130 miles). Some Brazilian studies measure the Amazon at up to 6,992 km using a more distant source, so the ranking is still debated.
How many mountains are higher than 8,000 meters?
There are 14, all in the Himalayas and Karakoram: Everest, K2, Kangchenjunga, Lhotse, Makalu, Cho Oyu, Dhaulagiri, Manaslu, Nanga Parbat, Annapurna, Gasherbrum I and II, Broad Peak and Shishapangma.
What is the deepest river in the world?
