Plate TectonicsKenneth Carrillo

Plates of the Earth make up the lithosphere.
A theory that explains the shift in plates and the direction in which they move.
Shift between 2cm to 10 cm a year
What are plate tectonics?
Help us understand the movement the Earth’s crust has made over many years.
The plates of the Earth include seven large pieces.
The African, South American, North American, Eurasian, Australian, Antarctic, and Pacific plates
There are also smaller plates that exist.
Plates of the Earth
The point at which two plates meet is called a plate boundary.
There are three different types of boundaries:
Convergent Plate Boundary Divergent Plate Boundary Transform Plate Boundary
Plate Boundaries
Divergent boundaries: plates move apart from each other.
Convergent boundaries: plates shift into each other.
Transform boundaries: plates move past each other laterally.
Plate Boundaries cont.
Plate tectonics shift the lithosphere in different directions.
Also earthquakes, eruptions of volcanoes, and tsunamis have taken place.
These dangerous disasters have killed thousands of people and animals.
Homes and belongings are also destroyed.
How does it affect life on Earth?
Knowledge scientists have of plate tectonics: Size Shape Distribution of continents, mountain ranges,
and ocean basins Moving Earth plates create volcanic
eruptions, earthquakes, and tsunamis.
Problem with the Plates
Plate tectonics are a natural process that cannot be prevented or stopped.
We can only try to be prepared for the disasters that may come along with moving plates.
GPS (Global Positioning System) can track the movement of Earth plates.
