1. D42 Plate Tectonics

2. D42 Plate Tectonics Background 1
Geologists today know that it is not just the continents that move – it is the entire surface of the Earth!
The Earth’s surface is broken into large sections called plates.
These plates not only include the surface of the Earth but also extend down into the solid part of the upper mantle.

3. D42 Plate Tectonics Background 1
This is one reason that geologists use the term “lithosphere” to describe the combination of solid crust and upper mantle.
Plate Tectonics is the movement of these lithospheric plates.
CHALLENGE QUESTION:
How did continental drift lead to the theory of plate tectonics?
