The Sun
This star gives Earth heat and light every day. What is it called?
The Sun
Jupiter has a giant storm that has been raging for over 300 years. What is this storm called?
The Great Red Spot
Uranus spins on its side because something big likely hit it long ago. What do we call the invisible line a planet spins around?
Its axis
Q: About 70% of Earth is covered in water, but only a tiny amount is fresh and usable for drinking. Most of Earth’s water is found in which type of water source?
Saltwater in the oceans
This planet is the closest one to the Sun. Which planet is it?
Mercury
We have daytime when our side of Earth faces the Sun. What do we call it when our side turns away?
Night
Jupiter has no solid surface because it is made mostly of gas. What do we call this type of planet?
Gas giant
Uranus is not a gas giant like Jupiter. It is made of icy materials such as methane, water, and ammonia. What type of planet is it?
An ice giant
Q: Earth spins once every 24 hours and orbits the Sun once every 365 days. What do we call Earth’s movement around the Sun?
Revolution
Mercury is one of the four rocky planets. What do we call this group of planets?
A: The terrestrial planets
True or false: The Sun is so big that more than one million Earths could fit inside it?

Jupiter’s strong gravity helps protect Earth by pulling in these space objects before they reach us?
Asteroids and comets
Because Uranus is tilted more than 90 degrees, each pole spends about 42 years in sunlight and 42 years in darkness. What do we call these long periods of weather change?
Seasons
The Moon’s gravity pulls on Earth’s oceans, causing the water to rise and fall in a regular pattern each day. What do we call these repeating changes in sea level?

Craters
The Sun is a middle‑aged star made mostly of two gases. Name the two gases.
Hydrogen and helium
Jupiter’s gravity is more than twice as strong as Earth’s. This strong pull creates powerful bands of wind that wrap around the planet. What do we call these colourful, striped layers?
Jupiter’s cloud bands (or atmospheric bands)
Uranus has 13 known rings, but they are much darker and harder to see than Saturn’s. What are these rings mostly made of?
