8th Grade STAAR Review: Category 3- Earth and Space (part II)

Theorized supercontinent that existed 200-300 million years ago.

• Pangaea

• Convection Currrent

• Mid-Ocean Ridge

• Divergent

Cycle of heating, rising, cooling and sinking that causes the plates to move.

• Pangaea

• Convection Currrent

• Mid-Ocean Ridge

• Divergent

System of underwater mountain ranges that stretch along the center of the ocean floor at divergent boundaries.

• Pangaea

• Convection Currrent

• Mid-Ocean Ridge

• Divergent

Hypothesis that stated the continents have moved slowly to their current location by drifting on top of the liquid core.

• Continental Drift Hypothesis

• Theory of Plate Tectonics

• Pangaea

• Divergent

Theory that Earth's crust and part of the upper mantle are broken into sections called plates that move on a plastic-like layer of the mantle.

• Continental Drift Hypothesis

• Theory of Plate Tectonics

• Pangaea

• Divergent

Boundary created when 2 plates pull away from each causing rifts, mid-ocean ridge and new crust to form.

• Transform

• Convergent

• Subduction

• Divergent

Boundary formed when 2 plates slide past each other causing a fault.

• Transform

• Convergent

• Subduction

• Divergent

Boundary formed when 2 plates come together and form continental mountains.

• Transform

• Convergent

• Subduction

• Divergent

A convergent boundary where one plate slides below the other causing trenches, island arcs and volcanic islands.
