Types of Plate Boundaries © Copyright M. J. Krech. All rights reserved.
There are four types of Plate Boundaries.
The first type of plate boundary 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 Valley The 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- SubductionBoundary are: 1.Volcanic Mountain Ranges 2.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.
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?
Theory of Plate Tectonics Plate Tectonics Plate Boundaries Causes of Plate Tectonics.
How Do Earths Plates Move? Chapter 1, Section 2, pD14-19.
1.How do the rocks of the crust and lithosphere compare? Rocks in the crust are less dense and made mainly of granite. The rocks in the lithosphere are.
The Structure of the Earth and Plate Tectonics. Structure of the Earth The Earth is made up of 3 main layers: –Core –Mantle –Crust Inner core Outer core.
Topic: Earth’s Features Essential Question: What crustal features are created by the movement of Earth’s plates?
Plate Tectonics. Brief Structure of the Earth Divided into layers: –Core, mantle, crust.
Do Now # 4 What is the difference between convergent, divergent, and transform boundaries?
The Theory of Plate Tectonics. Plate Tectonics Plate tectonics is the theory that explains why and how continents move. By the 1960s evidence supported.

Chapter 8: Plate TectonicsChapter 8: Plate Tectonics 8.1: Earth has several layers 8.2: Continents change position over time 8.3: Plates move apart 8.4:
Warm Up 11/ What hypothesis states that the continents were once joined to form a single supercontinent? a. continental driftc. plate tectonics.
Plate Boundaries and Plate Interactions. Goals Classify and label the types of movement at plate boundaries, using a world map that shows relative plate.
The Theory of Plate Tectonics. The lithosphere is divided into separate sections called plates. The plates carry continents and ocean crust or both.
Plate Tectonics. The Earth's surface is made up of a series of large plates (like pieces of a giant jigsaw puzzle). These plates are in constant motion.
Plate Tectonics 6.E.2.2 Explain how crustal plates and ocean basins are formed, move and interact using earthquakes, heat flow and volcanoes to reflect.

Imagine the Earth as a hardboiled egg……………………. The thin brittle shell is the crust that humans live on. The thick jelly like white is the deep hot magma.
Plate Tectonics What evidence do scientists have to support the fact that the Earths crust is continuously moving?
Choose a category. You will be given the answer. You must give the correct question. Click to begin.
Some questions we will answer today: –How is the earth always changing? –What forces inside the earth create and change landforms on the surface? –What.
