129 free Trivia for 10 Year Olds trivia questions with answers — trivia quiz, new questions added Oct 2026.
77 free trivia questions for 10 year olds with answers, pitched at the age where kids know a lot more than grown-ups expect but still love being surprised. There is a space round (the hottest planet, the smallest planet, what happened to Pluto), animals (the smallest bird, what a shark's skeleton is made of, why a dolphin is not a fish), world geography (capitals of Japan, Australia and Canada, the smallest country, the biggest reef), history (the Titanic, Machu Picchu, Anne Frank, the first hot air balloon), science (volcanoes, earthquakes, dinosaurs, Darwin and Newton) and a little art and music. The rest is the stuff 8 to 11 year olds actually talk about: Minecraft, Roblox, Fortnite, Among Us, Pokémon, Lego, Zelda, Frozen, Encanto, Toy Story, SpongeBob, Percy Jackson, Harry Potter and Taylor Swift, plus a sports round on basketball, hockey, golf, Wimbledon and the Olympics. Difficulty is mixed, so younger kids will get the easy ones and an 11 year old will still have to think. Every question is multiple choice with four answers and a one-line explanation that adds an extra fact. It works on a phone, read aloud in the car, or as a family quiz night. Every answer was checked against a reference page and shows its source once you have answered.

Q 01Which planet is the hottest in the Solar System, even though another planet sits closer to the Sun?
Venus
Venus. Its thick atmosphere traps the Sun's heat like a blanket in a runaway greenhouse effect, so the surface is hot enough to melt lead.
Q 02Which is the smallest planet in the Solar System?
Mercury
Mercury. It is so small that two moons, Jupiter's Ganymede and Saturn's Titan, are actually bigger than it is.
Q 03In 2006, Pluto was officially reclassified as what kind of object?
A dwarf planet
A dwarf planet. Astronomers ruled in 2006 that a full planet must clear other objects from its orbit, and Pluto shares its path with many icy bodies in the Kuiper belt.
Q 04A light-year is a unit used to measure what?
Distance
Distance. A light-year is how far light travels in one year, about six trillion miles, so the light you see from a star 100 light-years away set off a century ago.
Q 05Which scientist used his own telescope to spot the four largest moons of Jupiter?
Galileo Galilei
Galileo Galilei. Seeing moons circle Jupiter in 1610 was strong evidence that not everything revolves around Earth, a serious blow to the old Earth-centred picture of the universe.
Q 06Dinosaurs died out in a mass extinction roughly how many million years ago?
66
66 million years ago a giant asteroid struck what is now Mexico and wiped out most dinosaurs, but one branch survived as birds, so a pigeon is technically a living dinosaur.
Q 07What is the largest organ of the human body?
The skin
The skin. It never stops rebuilding itself: new cells push up from below while dead ones flake off the top, so you get a fresh outer layer roughly once a month.
Q 08Which adult teeth usually arrive last?
Wisdom teeth
Wisdom teeth. The four of them complete the adult set of 32, and the name, borrowed from Latin, reflects that they arrive at an age when people are supposedly wiser.
Q 09A shark's skeleton is made of which material instead of bone?
Cartilage
Cartilage. It is the same bendy stuff found in your nose and ears, and because it is much lighter than bone it helps a shark stay afloat and save energy.
Q 10Dolphins live in the sea, but which group of animals do they belong to?
Mammals
Mammals. Like all of them, dolphins breathe air, so they sleep with only half the brain at a time while the other half stays alert enough to surface for each breath.
Q 11Which is the smallest bird in the world?
Bee hummingbird
Bee hummingbird. Found only in Cuba, it weighs about two grams, and the female lays just two eggs at a time, each about the size of a coffee bean.
Q 12Which rainforest animal often looks green because algae grows in its fur?
Sloth
Sloth. Each of its long hairs has tiny grooves where algae grows, and the greenish tint helps the slow-moving animal hide among the treetop leaves.
Q 13What is the name for hot melted rock once it flows out of a volcano?
Lava
Lava. Underground the same melted rock is called magma, and lava that cools very quickly hardens into obsidian, a black natural glass sharp enough that people made blades from it.
Q 21Which purpose-built city became Australia's capital as a compromise between Sydney and Melbourne?
Canberra
Canberra. Neither rival would accept the other as capital, so a brand-new city was laid out between them to the winning plan of American architect Walter Burley Griffin.
Q 22Toronto is Canada's biggest city, but which city is its capital?
Ottawa
Ottawa. Rival cities could not agree on a capital, so the choice went to Queen Victoria, and in 1857 she picked Ottawa, a young timber town that had only just changed its name from Bytown.
Q 23Most of the Amazon rainforest is in which country?
Brazil
Brazil. About 60% of the rainforest lies inside it, and the forest is fed from another continent: winds carry dust from the Sahara across the ocean, and its minerals fertilise the trees.
Q 14Earthquakes happen mostly because of movement in what?
Tectonic plates
Tectonic plates. These huge slabs of Earth's outer shell creep along slowly, but their rough edges get stuck, and when they finally slip free the stored energy shakes the ground.
Q 15The Titanic sank on its very first voyage while sailing from England to which city?
New York
New York. The Titanic left Southampton, England, in April 1912 and struck an iceberg four days later, and its 20 lifeboats had room for only about half of the people on board.
Q 16Machu Picchu, the mountaintop city in Peru, was built by which people?
The Inca
The Inca. Their city sits nearly 8,000 feet up in the Andes, and because the Spanish invaders never found it, it is one of the few Inca sites that survived almost intact.
Q 17The Taj Mahal is in which country?
India
India. The Mughal emperor Shah Jahan built the white marble tomb for his wife Mumtaz Mahal, who died in 1631, and more than 20,000 workers laboured on it for about two decades.
Q 18The Colosseum, the giant ancient arena, is in which city?
Rome
Rome. The arena held about 50,000 spectators, and after earthquakes brought parts of it down, builders carted off the fallen stone to make palaces and churches elsewhere in the city.
Q 19The famous clock tower nicknamed Big Ben stands in which city?
London
London. Big Ben is really the nickname of the giant hour bell inside, and the tower itself was renamed the Elizabeth Tower in 2012 to mark Queen Elizabeth II's 60 years on the throne.
Q 20What is the capital city of Japan?
Tokyo
Tokyo. The city was called Edo until 1868, when the emperor moved there from Kyoto, the imperial home for over a thousand years, and it was renamed Tokyo, meaning eastern capital.
Q 24What is the smallest country in the world?
Vatican City
Vatican City. The whole country sits inside the city of Rome, ringed by old walls, and fewer than 1,000 people live in it.
Q 25Which is the biggest coral structure in the world, made up of about 2,900 separate sections?
Great Barrier Reef
Great Barrier Reef. It runs for well over 1,000 miles off north-east Australia, is big enough to be seen from space, and was built by tiny animals called coral polyps.
Q 26Anne Frank wrote her famous diary while hiding from the Nazis in which city?
Amsterdam
Amsterdam. Eight people hid for two years in a secret annex behind her father's office, and the way in was hidden behind a movable bookcase.
Q 27Helen Keller, who could neither see nor hear, was the first deafblind American to do what?
Earn a college degree
Earn a college degree. She graduated from Radcliffe College in 1904 after her teacher Anne Sullivan spelled the lectures and books into her hand, word by word.
Q 28Which artist painted the Mona Lisa?
Leonardo da Vinci
Leonardo da Vinci. The portrait shows the wife of a Florentine silk merchant, but Leonardo never handed it over to the family, and it ended up with the king of France instead.
Q 29Which famous ceiling in Rome did Michelangelo paint?
The Sistine Chapel
The Sistine Chapel. He spent about four years, from 1508 to 1512, painting scenes from Genesis, and he worked standing on scaffolding with his head tipped back, not lying down as many people imagine.
Q 30Which composer was already writing music at five and playing for kings and queens as a child?
Mozart
Mozart. He was composing little pieces at five, and at seven he set off with his sister on a concert tour of western Europe that lasted more than three years.
