What this practice covers
These questions are drawn from past CIE 0654 Co-ordinated Sciences papers and filtered to space physics. You answer, you find out immediately whether you were right, and you get the reasoning for the correct option and for each distractor. Wrong answers go to a mistakes locker so you can come back to exactly those.
Practice is free. You need an account only so your progress and your mistakes are still there next time.

What examiners see students get wrong here
These are the errors that cost marks on space physics, taken from our own topic notes. Read them before you practise and you will recognise the traps in the questions.
- Saying the seasons are caused by the Earth being closer to the Sun in summer.
- Saying day and night are caused by the Earth's orbit rather than its rotation.
- Saying the Moon gives out its own light.
- Saying the Sun has no effect on tides at all, or that it has the larger effect because it is more massive.
- Saying wind or hydroelectric power comes mainly from the Moon.
- Saying planets further out move faster because they have further to travel.
- Saying an orbiting planet has constant velocity. Its speed is constant; its direction, and so its velocity, is always changing.
- Saying the Sun releases energy by fission, or by burning its fuel.
Revise it first
