Plate Boundary Review

Movement-

- Plates slide past each other

What can form/happen?

​-Earthquakes

Transform Boundary

Multiple Choice

How do plates interact at a transform plate boundary?

• Plates collide

• Plates pull apart

• Plates slide past one another

Multiple Choice

What seismic activity is found at a transform plate boundary?

• Trenches

• Subduction

• Volcanoes

• Earthquakes

They come towards each other.


The less-dense plate slides under the more dense plate

​​How do the plates move?

1. ​Mountain Chains

2. Volcanoes

​​What is formed?

​Convergent Boundaries

Convergent Boundaries

When a continental plate collides with an oceanic plate, the oceanic plate will sink below the continental plate.

 

The region where one plate dives beneath another is called a subduction zone.

 

As one plate is subducted beneath the other, the rock melts under heat and pressure and transforms into magma.

 

Volcanoes are often found near convergent continental and oceanic plates.

When 2 oceanic plates smash into each other, one plate will sink beneath the other plate (creating a subduction zone), and volcanoes will form (some will be underwater volcanoes)

Convergent Boundaries

Multiple Choice

This is when two plates converge but one slides under the other due to density.

• Uplift
• Subduction
• Trench
• None of the above

Open Ended

Convergent Boundary - What forms when 2 convergent boundaries come together? (There is more than 1 correct answer)

Divergent Boundary

What is the movement on a divergent boundary?

 

 

Deep cracks form in Earth's crust as the plates separate. Called rift zones or rifts (form on continents or in ocean basins)

 

In the ocean, these rifts form underwater mountain chains (referred to as seafloor spreading)

 

Divergent Boundary

On the continental plates, a rift valley is formed in between 2 mountain ranges. 

Multiple Select

What forms when 2 plates pull away from each other?

• underwater mountains

• seafloor spreading

• vallys

• a big sink hole
