Plate 
Tectonics
What are tectonic plates? 
Plate tectonics 
is the theory 
that Earth's 
outer shell is 
divided into 
several plates 
that glide over 
the mantle, the 
molten rocky 
layer above the 
core. 
Plates move only 1-10 centimeters per year
How do the plates move? 
 Tectonic plates interact at locations 
called plate boundaries 
 There are three types of movement at 
plate boundaries
Three Basic Types of Plate Boundaries 
Divergent 
Convergent 
Transform 
USGS Graphics 
Using hands to show relative motion
What happens to the land where 
the plate boundaries move? 
Convergent 
boundaries are 
where plates 
collide - Mountains, 
earthquakes, and 
volcanoes form 
where plates 
collide.
What happens to the land where 
the plate boundaries move? 
Places where 
plates are coming 
apart are called 
divergent 
boundaries. Rift 
valleys and ocean 
ridges form at 
these boundaries
What happens to the land where 
the plate boundaries move? 
Places where plates slide 
past each other are called 
transform boundaries. The 
sliding motion causes 
earthquakes.
Let’s sing about it 
Plates are the crust, 
Heat from the Core, 
We got the whole world looking for more, 
The plates converge, 
Or they diverge, 
Or they slide past, past, past, past, past each other - 
transform 
Mountains, trenches, Earthy-Earthquakes, 
These things can happen when the crust breaks. 
The plates converge, 
Or they diverge, 
Or they slide past, past, past, past, past each other - 
transform
