Plate Tectonic Theory

• The Plate tectonic Theory was created by having the idea of continental drift. continental drift is where theres plates moving to form things. three are three different ways how plates in, they are Convergent Boundary, Divergent Boundary and Transform Boundary.

Convergent Boundary is when the plates collide to form mountains or landforms. when two plates move the hotter one will want to go up to the top because the particles are bouncing very fast so it can cool down. also when theres crack in the plates magma come to fill it in and this is called subduction.


Divergent Boundary is when the plates move apart from each other.


Transform Boundary is when the plates grind past each other to create earthquakes into the earth. Mostly in the Transform plate Boundary there will be many earthquakes.

• The earth has four layers, they are: crust, mantle, outer core, inner core.

Crust is also known as lithosphere. Crust is the thiniest layer and crust is made out of rocks and plates.

Mantle is made out of magma and mantle is the thickiest layer on the earth. Mostly Convection currents happens in the mantle.

Outer Core is liquid metal and the outer core causes magnetic field.

Inner Core is Solid metal and the inner core is dense.

• Some evidence to the plate tectonic theory is:

-Puzzle Look
-Fossils
-Mountain/Landform Location
-Mid Alantic Ridge
-Ocean Levels
-Subduction
-Convection Currents
-Climate
-Pangaea(A Supercontinent)
-Pressure
