Description
Understand that Earth's crust is broken into large pieces called tectonic plates that float on hotter, softer rock beneath and move very slowly — a few centimetres per year
Mastery Evidence
- Describe Earth's crust as broken into large plates
- Explain that the plates float on hotter, partially melted rock underneath
- State that plates move very slowly, typically a few centimetres per year
Assessment Prompt
If you showed your child a map of the tectonic plates, could they explain that Earth's surface is cracked into huge pieces that move very slowly — about as fast as their fingernails grow?
