S3.11.2 For the adult

Inside the Earth

What would you meet if you could dig down and down?

What this chapter teaches

The Earth has a thin solid crust, a thick mantle of hot rock that is mostly solid and flows very slowly, a liquid outer core and a solid inner core. The crust is broken into plates that move a few centimetres a year. Volcanoes and earthquakes are most common where plates meet.

Three questions to ask

There is no one right wording. Listen for the idea.

  1. Which layer of the Earth is liquid, and how do we know the mantle is not?
  2. Why do volcanoes and earthquakes mostly happen at the edges of plates?
  3. What should you do if the ground starts to shake while you are indoors?

After the chapter, the learner can

  • Label the crust, mantle, outer core and inner core
  • Explain how volcanoes and earthquakes happen where plates meet
  • Describe how to stay safe in an earthquake

What they copy into their notebook

The Earth has a crust, a mantle, a liquid outer core and a solid inner core. Plates move a few centimetres a year. Volcanoes and earthquakes happen where plates meet.
