1 Plate Tectonics

2 The Earth is made up of several layers:
Inner Core Outer Core Mantle Crust

3 Convection occurs a circular motion caused by heating and cooling
This is the process that causes the plates to move

4 Formation of Continents
The Earth is divided into “tectonic plates” that seemingly float on the Earth’s mantle The continents are parts of the Earth’s crust that extend higher than sea level (0 elevation) The continents are where they are today because of convection

7 When Worlds Collide The plates act on one another all the time
Convection moves them Tectonic plate movement causes the following recognizable formations Mountains, trenches, volcanoes, rifts

10 Other Results At plate boundaries, other things are likely to happen:
Earthquakes (strike-slip) Volcanic eruptions (convergent) Volcanic eruptions can happen anywhere the Earth’s crust is thin and there’s pressure underneath Ring of Fire

11 Types of boundaries Convergent Divergent Transform Coming together 
Moving apart  Transform Sliding past each other X
