These resources will be removed by end of Summer Term 2025.

Switch to our new teaching resources now - designed by teachers and leading subject experts, and tested in classrooms.

These resources were created for remote use during the pandemic and are not designed for classroom teaching.

Lesson details

Key learning points

  1. The theory of continental drift suggests that Earth’s continents were once joined together and later drifted apart.
  2. Evidence for continental drift includes continents' jigsaw like shape, rock type and fossils matching across continents.
  3. There are two types of crust; oceanic and continental crust.
  4. Oceanic crust is dense but thin and continental crust is thicker and less dense.
  5. Plates move by the processes of slab pull and ridge push.

Keywords

  • Continent - a large landmass on Earth. There are seven: Africa, Antarctica, Asia, Europe, North America, South America, Oceania

  • Tectonic plate - large sections of the lithosphere that are on the move

  • Density - the mass of something compared to its volume

Common misconception

South America and the South American plate are the same thing.

South America is a continent (land), whereas the South American plate also includes part of the Atlantic ocean.

It is possible to model slab pull by using a chain or scarf hanging off the edge of a table. Let the students see how the weight of the item drags the rest of it down off the table.
