What are the 3 different plate margins?
There are three main types of plate boundaries:
- Convergent boundaries: where two plates are colliding. Subduction zones occur when one or both of the tectonic plates are composed of oceanic crust.
- Divergent boundaries – where two plates are moving apart.
- Transform boundaries – where plates slide passed each other.
What are the main plate margins?
There are four main types of plate boundary. These are constructive, destructive, conservative and collision margins.
How many plate margins are there?
There are three types of plate boundaries: divergent, convergent and conservative.
Why is convergent boundary destructive?
A destructive plate boundary is sometimes called a convergent or tensional plate margin. This occurs when oceanic and continental plates move together. The oceanic plate is forced under the lighter continental plate. Friction causes melting of the oceanic plate and may trigger earthquakes.
What are the examples of divergent boundary?
Examples
- Mid-Atlantic Ridge.
- Red Sea Rift.
- Baikal Rift Zone.
- East African Rift.
- East Pacific Rise.
- Gakkel Ridge.
- Galapagos Rise.
- Explorer Ridge.
What are the types of plate boundaries?
Most seismic activity occurs at three types of plate boundaries—divergent, convergent, and transform. As the plates move past each other, they sometimes get caught and pressure builds up.
What is continental plate margin?
A destructive plate margin usually involves an oceanic plate and a continental plate. The plates move towards one another and this movement can cause earthquakes. As the plates collide, the oceanic plate is forced beneath the continental plate. This is known as subduction .
How many types of plate boundaries are there?
There are three kinds of plate tectonic boundaries: divergent, convergent, and transform plate boundaries. This image shows the three main types of plate boundaries: divergent, convergent, and transform. Image courtesy of the U.S. Geological Survey.

What are the 3 types of convergent plate boundaries?
What are the three different types of convergent plate boundaries? 1. Continental – Continental 2. Continental – Oceanic 3. Oceanic – Oceanic. What is an example of a continental – continental plate boundary? The Alps and the Himalayas. What is another name for a continental – oceanic boundary?
What are three plate boundaries?
What Are the Three Types of Plate Boundaries? There are three types of plate boundaries: convergent, when tectonic plates come together; divergent, when tectonic plates are moving away from each other; and transform, when two plates are sliding past one another.
What are the four types of plate movement?
– Two plates move toward each other – Also known as ‘destructive plate boundary’ as land is destroyed – Come in different forms, depending on the types of plates involved
