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
3.
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.
4.
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
5.
Divergent boundaries: plates move apart
from each other.
Convergent boundaries: plates shift into
each other.
Transform boundaries: plates move past
each other laterally.

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.
8.
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.
9.
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.
