How many plate boundaries are there?
3
What are divergent plate boundaries?
When tectonic plates move away from each other.
What are convergent plate boundaries?
When two plates collide with each other.
What is the definition of transform plate boundaries?
When tectonic plates slide against each other

How fast do tectonic plates move?
2-5cm per year
Where does divergent plate boundaries happen?
Underwater
What are the two tectonic plates involved in this boundary?
Continental and oceanic
What natural disaster is created by this boundary?
Earthquakes
The two types of od tectonic plates are called?
Continental and oceanic crust
What are plate boundaries?
When tectonic plates come into contact with each other it is called plate boundaries
What is magma?
Hot fluid in the Earth's crust

Answers may vary
What kind of natural disaster does this boundary cause?
Earthquakes and volcanoes
Why will one plate sink under the other?
Because it is denser
What is another name for Transform plate boundary?
Transform fault
What is the movement of tectonic plates called?
Plate tectonics
What happens during mid-ocean ridge?
The magma in Earth's surface comes up to the water and cools. When they cool down they turn to crust. The magma will continue coming to the surface causing the crust to be pushed outward, this causes seafloor spreading
1. What is formed when two continental crust collide with each other?
2. What happens when a continental crust collides with an oceanic crust?
1. Mountains are formed.
2. The oceanic crust will sink under and melt into magma which can cause volcano eruptions.
What is an example of a transform fault
San Andreas fault
