Planet Earth and its Movements

In this chapter you learnt that the Earth rotates on its own axis while travelling around the Sun, and what this means for day changing to night and the passage of seasons throughout the year.

You have understood:

• The science behind what it means to say the Sun rises and sets
• What an axis is and how fast the Earth spins on it, taking 24 hours for a complete rotation
• The Earth’s 365- day orbit around the sun, and how its two hemispheres experience spring, summer, fall and winter at different times.
