Tectonic Plates 2020

Huge pieces of lithosphere that slowly move on the asthenosphere and consist of the crust and the rigid, uppermost part of the mantle

• tectonic plates

• North American Plate

• Eurasian Plate

• African Plate

The place where two different plates have contact.

• Pacific Plate

• Mountains

• Earthquakes

• Plate Boundaries

Occurs when two tectonic plates move toward each other and collide (the plates come together)

• convergent boundary

• subduction

• volcanic eruptions

• divergent boundary

The process in which a denser plate is pushed downward beneath a less dense plate when plates converge; occurs at continental to oceanic boundaries and oceanic to oceanic boundaries

• divergent boundaries

• volcanic eruptions

• subduction

• convergent boundary

Occurs when two tectonic plates move away from each other (in different directions)

• Divergent Boundary

• Convergent Boundary

• Volcanic eruptions

• Mountain building

Occurs when two tectonic plates slide past each other

• Transform Boundary

• Ocean Basin

• Divergent Boundary

• Spreading ridges
