Plant actions like them growing in between cracks causing the shifting and deforming of rocks.
What is Pangea?

What are plate tectonics?

What is the scale called that measures the magnitude of an earthquake?
Richter Scale
What is a shield volcano?
A volcano that erupts and is covered in liquid known as lava.
How do sinkholes form?
Sinkholes form because of chemical weathering where chemicals cause the ground to cave in.
What is evidence supporting the existence of Pangea?
Similar fossils found in different continents when they are separated from water.
Similar mountain ranges and plants found in different continents although they are separated by oceans.
What are some ways to stay safe during an earthquake?
Stay inside and be away from windows and walls.
