Continent Drift and Plate Tectonics Review

What is continental drift?

• The theory that explains how the Earth's continents have collided and merged over time.

• The theory that explains how the Earth's continents have remained stationary over time.

• The theory that explains how the Earth's continents have disappeared over time.

• The theory that explains how the Earth's continents have moved over time.

Who proposed the theory of continental drift?

• Alfred Wegener

• Marie Curie

• Isaac Newton

• Charles Darwin

What evidence supports the theory of continental drift?

• The alignment of mountain ranges is purely coincidental.

• The theory of continental drift is based on fabricated data.

• The movement of tectonic plates is a myth.

• The matching shapes of coastlines, the distribution of fossils across continents, and the alignment of mountain ranges.

How did the theory of continental drift change our understanding of Earth's history?

• The theory of continental drift claims that the continents were created by a series of earthquakes.

• The theory of continental drift proposed that the continents were once joined together in a single landmass called Pangaea and have since moved apart over time.

• The theory of continental drift proposes that the continents were formed by volcanic activity.

• The theory of continental drift suggests that the continents are stationary and have not moved over time.

What are the major tectonic plates?

What are the three types of plate boundaries?

• Subduction boundaries, collision boundaries, and sliding boundaries

• Tectonic boundaries, fault boundaries, and rift boundaries

• Oceanic boundaries, continental boundaries, and island boundaries

• Divergent boundaries, convergent boundaries, and transform boundaries

What causes tectonic plates to move?

• Convection currents in the mantle

• Gravity

• Earth's rotation

• Friction

What are the consequences of plate tectonics?

• formation of mountains, earthquakes, volcanic activity, and creation of new landforms

• depletion of natural resources, decrease in biodiversity, and change in atmospheric composition

• formation of deserts, increase in rainfall, and change in ocean currents

• erosion of land, melting of glaciers, and change in climate
