Exploring Continental Drift and Tectonics

Who proposed the theory of continental drift?

• Marie Curie

• Isaac Newton

• Alfred Wegener

• Charles Darwin

What was the name of the supercontinent that existed millions of years ago?

• Atlantis

• Laurasia

• Pangaea

• Gondwana

What evidence did Alfred Wegener use to support his theory?

• Wegener's evidence was based solely on ocean currents.

• Wegener's evidence included the fit of continents, fossil correlations, geological similarities, and paleoclimatic data.

• Wegener relied on the movement of tectonic plates exclusively.

• Wegener used only satellite imagery to support his theory.

What are the two main types of tectonic plates?

• Volcanic plates and tectonic plates

• Inner core plates and outer core plates

• Sedimentary plates and metamorphic plates

• Oceanic plates and continental plates

What is the difference between oceanic and continental plates?

• Oceanic plates are thinner and denser than continental plates, which are thicker and less dense.

• Oceanic plates are thicker and denser than continental plates.

• Continental plates are found only on land, while oceanic plates are found only in oceans.

• Both oceanic and continental plates are equally thick and dense.

What geological feature is formed at convergent boundaries?

• Rift valleys

• Plateaus

• Sand dunes

• Mountain ranges, deep ocean trenches, and volcanic arcs.

What type of plate boundary is characterized by plates sliding past each other?

• Divergent boundary

• Transform boundary

• Subduction zone

• Convergent boundary

What is the process called when tectonic plates move apart?

• Continental drift

• Subduction zone

• Seafloor spreading

• Plate tectonics

How do tectonic plates affect earthquakes?

• Tectonic plates only affect ocean currents, not seismic activity.

• Tectonic plates cause earthquakes by moving and interacting at their boundaries, creating stress that is released as seismic energy.

• Earthquakes are caused solely by volcanic activity, not tectonic plates.

• Tectonic plates are stationary and do not cause earthquakes.

What role do tectonic plates play in the formation of mountains?

• Tectonic plates create mountains through volcanic activity alone.

• Tectonic plates cause mountains to form primarily through the process of convergence, where plates collide and push the Earth's crust upwards.

• Tectonic plates have no impact on mountain formation.

• Mountains are formed by the erosion of tectonic plates over time.
