What is Plate Tectonics?
Plate Tectonics is the geologic theory that
explains geologic activity of the earth resulting from the
slow movement of large sections or lithospheric
slabs called plates. In Plate Tectonics, the Earth's
crust is composed of rigid and large plates that constantly
move over a less rigid layer.
What are tectonic plates?
Tectonic plates are large slabs of rock that
make up Earth's lithosphere. Tectonic plates can carry lots of
different geological formations such as continents, oceans or
How many tectonic plates are there?
There are 14 large, irregular shaped
tectonic plates and there are many smaller tectonic plates.
Each tectonic plate has a name. The largest tectonic plate is
called the Pacific plate. Pacific plate carries the Pacific
Ocean. The smallest tectonic plate is the Juan de Fuca plate
which lies along the northwest coast of North America. Small
tectonic plates are referred to as microplates.
Theory of Plate Tectonics
The theory of plate tectonics was developed
and accepted by scientists in the 1960s. Over time, the theory
of plate tectonics has become a fundamental theory in geology.

drifting continents as well as describing Earth's geological
