Types of Plate Boundaries© Copyright 2008. M. J. Krech. All rights reserved.
There are four types of Plate Boundaries.
The first type of plate boundary Divergent means: moving apart.is called Divergent. Divergent means: moving apart.
The Mid-Atlantic Ridge is an example of a Divergent Plate Boundary :
Another example of a Divergent Plate Boundary is Iceland, which is splitting apart down the middle.
Features of a Divergent Boundary: (1) Rift ValleyThe Álfagjá Rift Valley in southwest Iceland Most of the world’s rift valleys are on the ocean floor.
(2) Mid-Atlantic Ridge Mountains or Volcanoes
The second type of plate boundary is called Convergent.Convergent means: moving together.
There are two types of Convergent Boundaries.The first is: Convergent - Subduction. In this type of Convergent Boundary, the denser plate subducts under the less dense plate.
Features of a Convergent- Subduction Boundary are:Volcanic Mountain Ranges Trenches
The Andes Mountains are an example of a Volcanic Mountain Chain formed by a Convergent-Subduction Boundary. The Nazca Plate is subducting under the South American Plate, forming the Andes Mtns.
The Mariana Trench is an example of a Trench formed by a Convergent-Subduction Plate Boundary.The Pacific Plate is subducting under the Eurasian Plate.
Another type of Convergent Plate Boundary is the Convergent - Collision Boundary.Two plates of the same density collide and form Folded Mountains.
Features of a Convergent-Collision Boundary are:Folded Mountains
An example of a Convergent-Collision Folded Mountain is the Himalayan Mtns.
with the Eurasian continent.India is colliding with the Eurasian continent.
The fourth type of Plate Boundary is the Transform-Sliding Boundary.These plates slide past each other.
The Features of a Transform-Sliding Boundary are:Earthquake Zone or Fault Zone
An example of a Transform-Sliding Plate Boundary is the San Andreas Fault Zone in California.
Views from the air of the San Andreas Fault Zone.
The Mid-Atlantic Ridge also has sliding (transform) boundaries.
The End BONUS: (1) Does your state sit on a Plate Boundary? (2) How do you know?

Types of Plate Boundaries
Divergent Boundary spreads apart, or divides, making new ocean floor along mid ocean ridges. Convergent Boundary comes together. Ocean crust sinks.
Plate Boundaries. Divergent Plate Boundary Description of Plate Boundary & Motion at Boundary: ON LAND – two plates spread apart; crust separates and.

Plate Boundaries Convergent – 2 plates moving towards each other.
Scientists identify the boundaries between two plates by the plate movement. There are three types of plate boundaries: 1. Divergent 2. Convergent.
