Convergent Boundary:Plate motion is when the two tectonic plates come together or mover towards each other. The stress for Convergent Boundaries is compression. This boundary can form Mountains, Earthquakes, Volcanoes.
Divergent Boundary:Plate motion is when the two tectonic plates mover away from each other. The stress for Divergent Boundary is tension. This boundary can form Faults, Earthquakes, and Rift Valley.
Mid-Atlantic Ridge, it was discovered in the 1950s. The Atlantic is growing at the Ridge because the plates are still moving apart.
Transform Boundary:Plate motion is when the two tectonic plate do not converge or diverge but they slide past each other. The stress for Transform Boundary is shear. This boundary has landforms like Faulting and Earthquakes.
