Worked practice questions

The Earth spins on its own axis. What is this spinning called?

  1. Its revolution
  2. Its rotation
  3. Its reflection
  4. Its refraction
Show answer and solution

Correct answer: B. Its rotation

1. The Earth does two separate movements at the same time. 2. Spinning on its own axis is called rotation, and one turn takes a day. 3. Travelling around the Sun is called revolution, and one trip takes a year. _Source: Siyavula Natural Sciences Grade 7 (CC BY 4.0), Earth's revolution_

Why does a planet far from the Sun take longer to complete one year?

  1. Its orbit around the Sun is smaller
  2. It spins much faster on its axis
  3. It has a much smaller mass
  4. Its orbit around the Sun is bigger
Show answer and solution

Correct answer: D. Its orbit around the Sun is bigger

1. One year is the time a planet takes to travel once around the Sun. 2. A planet further out has a much bigger path to travel. 3. Covering a bigger path takes more time, so its year is longer. 4. Spinning speed sets the length of a day, not the length of a year. _Source: Siyavula Natural Sciences Grade 7 (CC BY 4.0), Earth's revolution_

What causes the seasons on Earth?

  1. The tilt of the Earth's axis
  2. The changing distance to the Sun
  3. The speed of the Earth's spin
  4. The size of the Earth's orbit
Show answer and solution

Correct answer: A. The tilt of the Earth's axis

1. The axis of the Earth is tilted and always points the same way in space. 2. As the Earth travels around the Sun, first one half then the other leans towards it. 3. The half leaning towards the Sun receives more direct sunlight and has summer. 4. The distance between the Earth and the Sun changes far too little to explain this. _Source: Siyavula Natural Sciences Grade 7 (CC BY 4.0), Why do we have seasons?_
