Reading Guide Plate Tectonics

The movement of tectonic plates is primarily driven by ________.

• Ocean currents

• Mantle convection

• Wind patterns

• Solar energy

What evidence supports the theory of plate tectonics?

• A) Distribution of earthquakes

• B) Fossil evidence

• C) Sea-floor spreading

• D) All of the above.

What is the significance of fossil evidence in plate tectonics?

• It shows that continents were once connected

• It indicates the presence of ancient life

• It explains ocean currents

• It supports wind patterns

Sea-floor spreading provides evidence for plate tectonics by showing that ________.

• New crust is created at mid-ocean ridges

• Continents are stationary

• Ocean currents are constant

• Wind patterns are stable

Which geological feature is formed at convergent plate boundaries?

• Mountains

• Mid-ocean ridges

• Earthquakes

• Volcanoes

The alignment of mountain ranges on different continents supports the theory of ________.

• Continental drift

• Ocean currents

• Wind patterns

• Solar energy

The distribution of earthquakes along plate boundaries is evidence for ________.

• Plate tectonics

• Ocean currents

• Wind patterns

• Solar energy

What is the implication of plate tectonics for understanding geological processes?

• It helps explain the formation of mountains

What happens at a divergent boundary?

• A) Plates move towards each other

• B) Plates move away from each other
