Pangea
What is Pangea?
a supercontinent
What are transform boundaries
When two plates slide past each other
What do convergent boundaries create?
Mountains.
Do plates interact with each other?
Yes!
What continents did Pangea split into?
(What are the continents today?)
Asia, Africa, North America, South America, Antarctica, Europe, and Australia
What happens to places with fault lines?
Places with fault lines have more frequent earthquakes.
What are convergent boundaries?
A convergent boundary is where two tectonic plates collide, causing natural disasters.
What are divergent boundaries?
Divergent boundaries are when two tectonic plates move away from each other and create gaps.
Where are tectonic plates?
Tectonic plates are chunks of rock that make up the Earth's outer shell.
How long ago was pangea changed?
3 million years ago
Fault lines
What can Convergent Boundaries cause?
Earthquakes, volcanoes, and sometimes the formation of mountains
What types of boundaries are there?
Divergent, convergent, and transform
Name two continents before Pangea.
Rodinia, Columbia, and even earlier ones like Ur and Vaalbara.
What has the most fault lines?
The Ring of Fire
What comes up from the gaps that divergent boundary cause?
Magma
When do these plates move?
They can move 1-10 centimeters each year.
What are the continents in the second phase of continental drift?
Laurasia and Gondwana
Name a famous fault line.
Acceptable answers:
San Andreas Fault, Alpine Fault, or North Anatolian Fault.
What usually happens when the plates bump for convergent boundaries?
One slides under the other
What does the magma that comes up from the gap form?
New land
What are all the things that tectonic plates can create?
They can cause earthquakes, volcanic activity, mountain formation, and continental drift.
