Transcript of Y7 L1 - Introduction to Continental Drift

Task 1
- Watch the first YouTube video clip below. Be prepared to give feedback on what the theme of the film is.
The Earth’s crust (top layer) is not a solid shell. It is made up of thick, connecting pieces called tectonic plates. These fit together like a puzzle.
Underneath the plates is thick, soft, hot flowing rock called mantle.

This is what makes tectonic plates move around like a puzzle and not be solid.
A supercontinent!
Scientists believe that 220 million years ago, today’s continents may have all been joined together as one supercontinent called Pangaea.

They looked at maps and saw the continents looked like they fit together like a puzzle.

They also found that there are similar rock types, deserts and fossils in the places where the continents look like they would join.

A Plate Tectonics Puzzle
What’s the code?
Use the legend to identify the symbols on each island or continent.
Puzzle me this.
Look at the shapes of continents and islands.What landmasses seem to fit together?
Let’s rock!
Examine the evidence and try to match up landmass boundaries that show similar rocks, fossilized desert belts, and dinosaur fossils.
Hold that Pose.
Look over the arrangement of the continents and islands and decide if the position of any of them should change. Once you're happy, tape or glue it down on the world map.
The correct answer!
LO: To find if Earth has always looked the same and to find out what continental drift means.
Introduction to Continental Drift
Solve the puzzle to discover what the Earth looked like 220 million years ago.
Write a paragraph to describe continental drift & what happened to the Earth over 220 million years.

Task 3 - Watch the video below to see a brief history of continental drift. Enjoy the music!
How different would the world be if it looked like this?!
