What geological events are explained by the Theory of Plate Tectonics?

• Weather patterns

• Ocean currents

• Mountain building, earthquakes, and volcanic activity

• Erosion and sedimentation

What happens when a mid-ocean ridge extends above the water's surface?

• It forms a trench

• It forms a plateau

• It forms an island

• It forms a valley

What allows the plates to move across the asthenosphere?

• Gravity

• Plasticity

• Magnetism

• Friction

What are the three types of convergent plate boundaries?

• Continental/continental, oceanic/continental, oceanic/oceanic

• Continental/continental, oceanic/continental, transform

• Oceanic/oceanic, transform, divergent

• Transform, divergent, subduction

What are areas of subduction called?

What type of plate boundary is the San Andreas Fault an example of?

• Convergent boundary

• Divergent boundary

• Transform boundary

• Subduction zone

What is a fault in the Earth's crust?

• A mountain range

• A break in the Earth's crust

• A type of volcano

• A river valley

What forms as a plate slowly moves over a stationary hotspot?

• A line of volcanoes

• A mountain range

• An ocean trench

• A desert

What formed the Hawaiian Islands?

• A convergent boundary

• A hotspot under the Pacific Plate

What is the role of extra heat in forming a volcano at a hotspot?
