Tectonic Plate Boundaries
12/11/14

Complete a foldable :]You need three tabs- one for each boundary type (convergent, divergent, transform)
The front:
Boundary type
Picture of what the plates are doing
Key word to help remember
The inside:
Definition of plate boundary (what are the plates doing?)
The different types of crust
What each type of crust forms at each boundary
Real life examples

How do the plates move?
Convection currents, in the plastic like layer of the mantle of the earth, constantly churn in a circular motion, the hot magma rises, cools, then falls back down to the core. This movement causes tectonic plates to meet at plate boundaries .

Plate BoundariesConvergent- tectonic plates collide or combine
• Divergent- tectonic plates move apart from each other
• Transform/Transverse- tectonic plates slide/grind past each other

3. Continental – Oceanic crust
• Dense oceanic plate subducts under less dense continental plate, which creates a subduction zone.
• This can create ocean trenches (rarely), and very violent subduction volcanoes such as Mt. St. Helens. Ring
of fire- Pacific Plate
Convergent Boundaries1. Continental-Continental
crust
Fold mountains, mountain ranges. EX: The Himalayas
2. Oceanic- Oceanic crust
Creates deep trenches
Sometimes volcanoes can be formed
Ex: Marianas Trench

Oceanic-continental convergence

Divergent boundaries
Continental- Continental crust
Forms Rift Valleys, water can fill in the rift (new ocean)
Ex: The Great African Rift
Oceanic- Oceanic crust
Remember the seafloor spreading theory??
Forms mid ocean ridges
Older crust is found further away from the ridge, while younger crust is found just near the ridge.
Ex: Mid-Atlantic Ridge

Transform boundaries
Forms Transform Faults and fault lines (zones)
Ex: The San Andreas Fault line- North American Plate and the Pacific Plate

Remember! :]
Convergent- collide
Divergent- divide
Transform plates- slide
