The Earth is made up of 4 layers. What are these layers called?

• crust, magma, outer core and inner core

• oceanic crust, continental crust, mantle and outer core

• inner core, outer core, mantle and crust

• surface, mantle, magma and core

The temperature at the core is about 5500°C

• TRUE

• FALSE

The distance to the centre of the Earth is about 400km?

• True

• False

Which of the following statements best describes the outermost layer of planet Earth?
