49 free Nile River trivia questions with answers — geography quiz, new questions added Sep 2026.
The Nile is the longest river on Earth, and almost everything about it surprises. It flows north, its longest branch is not its biggest, its water mostly comes from Ethiopian rain, its present course is only about 15,000 years old, and it once carved a gorge 2,400 metres deep beneath modern Cairo when the Mediterranean dried up. This quiz covers the geography (sources, tributaries, the Sudd, the six cataracts, Lake Nasser, the shrinking delta), the hydrology (why the Blue Nile floods, how much the Sudd evaporates, what a nilometer measures) and the wildlife, from crocodiles and hippos to the invasive perch that wiped out 500 cichlid species. It also follows the river through history: the flood calendar of the pharaohs, the Kushite black pharaohs of Napata and Meroe, Herodotus and the Mountains of the Moon, Pedro Páez at Gish Abay, John Hanning Speke at Lake Victoria, the Aswan dams and the rescue of Abu Simbel, and today's fight over the Grand Ethiopian Renaissance Dam. Culture gets a look-in too, with Verdi's Aida, Bernini's fountain and Agatha Christie's Death on the Nile. Every answer was checked against Wikipedia's article on the Nile, and each question shows the sentence that supports it.

Q 01Into which sea does the Nile empty?
The Mediterranean
The Mediterranean meets the Nile at a fan of sediment shaped like the Greek letter delta, and every other river delta takes its name from this one.
Q 02Which river rivals the Nile for the title of the longest in the world?
Amazon
The Amazon carries far more water, and a 2007 Brazilian expedition claimed it was longer too; the answer depends on where each river is judged to begin.
Q 03In which direction does the Nile flow?
North
North: the current carried ancient boats downstream towards the delta, while steady winds from the north let them sail back upstream.
Q 04In the Book of Exodus, which baby was hidden in a basket among the Nile's reeds?
Moses
Moses was found there by Pharaoh's daughter, who unknowingly paid the baby's own mother to nurse him.
Q 05The two great branches of the Nile meet at which capital city?
Khartoum
Khartoum is where a pale river meets one heavy with soil from the Ethiopian Highlands, and the two streams run side by side in different shades.
Q 06The Blue Nile flows out of which Ethiopian lake?
Tana
Tana feeds the river in Ethiopia's highlands, where many hold its upper course holy as the Gihon, a river of Eden in Genesis.
Q 07Which British naval commander destroyed Napoleon's fleet at the 1798 Battle of the Nile?
Horatio Nelson
Horatio Nelson won it at sea, not on the river: he caught the French at anchor in Aboukir Bay, where their flagship L'Orient blew up in the night.
Q 08Which country shares Lake Victoria and so sits in the eleven-nation Nile Basin?
Kenya
Kenya holds only about 6% of the lake, with Uganda and Tanzania splitting the rest, but that sliver makes it one of eleven countries sharing the river's basin.
Q 09The Nile's most distant source, a Rukarara tributary, is in which country's Nyungwe National Park?
Rwanda
It sits at 2,539 metres and feeds the Kagera River, which drains into Lake Victoria.
Q 10At which Ugandan falls is the whole Nile forced through a rock gorge less than ten metres wide?
Murchison Falls
Murchison Falls squeezes the river through the gap into a pool called the Devil's Cauldron; Ernest Hemingway survived a plane crash just downriver in 1954.
Q 11What is the vast South Sudan swamp where the Nile loses about half its water to evaporation called?
The Sudd
The Sudd soaks up so much water that engineers began digging the Jonglei Canal to bypass it in 1978, only for war to halt the work within a few years.
Q 12Which tributary joins the White Nile from the west at Lake No?
Bahr el Ghazal
Bahr el Ghazal, the river of gazelles, drains a vast basin yet adds almost no water to the Nile, because most of it is lost in swamps along the way.
Q 13What swells the Blue Nile each summer, producing the flood that fed ancient Egypt?
Monsoon rains
Monsoon rains drench the Ethiopian Highlands from June to September, so the flood reached Egypt under cloudless skies, far from any storm its farmers could see.
Q 21The three seasons of the ancient Egyptian calendar were Akhet, Peret and Shemu; what did Akhet mean?
Inundation
Inundation came with a warning in the sky: the bright star Sirius returned to the dawn horizon just as the river began to rise, so its reappearance marked the New Year.
Q 22Which two plants represented Lower and Upper Egypt respectively?
Papyrus and sedge
Papyrus and sedge: the second is drawn in the pharaoh's throne title, written with a sedge and a bee, which named its holder king of both halves of the country.
Q 23The kingdom of Kush, whose 'Black Pharaohs' once ruled Egypt, had which two Nile cities as its capitals?
Napata and Meroë
Q 14Which African river, fed by rain on the Equator, carries over ten times the Nile's water?
Congo
The Congo drains a rainforest basin astride the Equator, while the Nile loses much of its water to evaporation in swamps and desert before it reaches Egypt.
Q 15What has the Nile Delta done since the Aswan High Dam began trapping silt?
Shrunk
Shrunk: the delta's soil began as rock in the Ethiopian Highlands, and with that supply cut off the sea now wears the coast away faster than it is rebuilt.
Q 16What are the six rocky rapids that interrupt the Nile in Sudan and Egypt called?
Cataracts
Cataracts is a grand word for them, since none is a true waterfall, yet for centuries these rapids stopped boats sailing straight through to Egypt.
Q 17Which Egyptian president built the Aswan High Dam and gave his name to the vast lake behind it?
Gamal Abdel Nasser
Gamal Abdel Nasser turned to the Soviet Union for money and engineers after the United States withdrew its offer to fund the dam.
Q 18The Nile Delta splits into which two main distributary branches?
Rosetta and Damietta
Rosetta and Damietta are both port towns too, and it was at Rosetta in 1799 that an officer in Napoleon's army pulled the Rosetta Stone out of an old wall.
Q 19Priests read the Nilometer's flood level each year so that officials could set what?
Taxes
Taxes: a good flood meant a good harvest, so the reading on the gauge set how much would be owed that year.
Q 20The ancient Egyptians called their country 'kmt', meaning 'black', in reference to what?
The dark colour of the flood silt
The dark colour of the flood silt marked the farmland, the Black Land, off from 'deshret', the Red Land of desert on either side.
Napata and Meroë both still have fields of steep-sided pyramids, because the Kushite kings who had worn Egypt's crown chose to be buried the old Egyptian way.
Q 24Which Egyptian god was responsible for the annual flood?
Hapy
Hapy was drawn as a plump man with heavy breasts and blue or green skin, a body meant to show the abundance his waters brought.
Q 25Why were many ancient Egyptian burial sites placed on the west bank of the Nile?
To be nearer the setting sun
To be nearer the setting sun was to be nearer the afterlife: Ra was thought to die in the west each evening and be reborn in the east, so the dead got the sunset side.
Q 26The legendary Mountains of the Moon described by Ptolemy are associated with which range?
Rwenzori
The Nile's highest sources lie on their slopes in Uganda.
Q 27Which Greek writer, called the Father of History, puzzled over a Nile that flooded in the rainless summer?
Herodotus
Herodotus was told that melting snow far to the south fed the flood and scoffed, asking how snow could lie in the hottest part of the world.
Q 28Which missing explorer, tracked down by Henry Morton Stanley in 1871, had been searching for the source of the Nile?
David Livingstone
David Livingstone had wandered far to the west and was tracing a river he took for the upper Nile; it was the Lualaba, which never joins the Nile at all.
Q 29Which European first saw Lake Victoria in 1858 and declared it the source of the White Nile?
John Hanning Speke
John Hanning Speke was due to debate his doubting rival Richard Burton in 1864, but the day before he fatally shot himself while out hunting partridge.
Q 30Which Egyptian god, worshipped along the Nile, was shown as a man with a crocodile's head?
Sobek
Sobek's temples kept tame crocodiles in their own pools, where priests hand-fed them, hung them with gold and jewels and mummified them when they died.
