STAAR REVIEW: EARTH SCIENCE (CATEGORY 3)

Exists between two tectonic plates that are moving away from each other

• Divergent Boundary

• Convergent Boundary

• Transform Boundary

• Plate Boundary

Landform created by two diverging continental plates

• Volcanic Island

• Trench

• Rift Valley

• Mountain

An underwater mountain system formed by diverging oceanic plates

• Mountains

• Mid-Ocean Ridges

• Volcanic Islands

• Trench

The formation of new areas of oceanic crust, which occurs through the upwelling of magma at midocean ridges and its subsequent outward movement on either side

• Seafloor Spreading

• Continental Drift

• Plate Tectonics

• Monkey Bread

Tectonic plates that move toward one another

• Convergent

• Divergent

• Transform

• Interstitial

Takes place at convergent boundaries of tectonic plates where one plate moves under another and is forced or sinks due to gravity into the mantle

• Mountain Formation

• Volcanic Mountains

• Rift Valleys

• Subduction

Major area in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur

• Pacific Rim

• Ring of Fire

• Fast & Furious

• Fire Ring of Glory

Tectonic plates that slide past each

• Convergent

• Divergent

• Transform

• Subducting

A sudden and violent shaking of the ground, sometimes causing great destruction, as a result of movements within the earth's crust or volcanic action

• Tornado

• Earthquake

• Hurricane

• Tsunami

Formed at the boundary of two converging continental tectonic plates

• Mountain

• Rift Valley

• Trench

• Fault
