Continental Drift

What is continental drift?

• The movement of the Earth's continents relative to each other.

• The process of continents sinking into the ocean

• The movement of the Earth's core

• The rotation of the Earth on its axis

Who proposed the theory of continental drift?

• Charles Darwin

• Marie Curie

• Isaac Newton

• Alfred Wegener

What evidence supports the theory of continental drift?

• The number of rivers on each continent

• The fit of the continents, matching geological formations, and the distribution of fossils and ancient climates

• The color of the ocean water

• The height of the mountains

What are the major tectonic plates that make up the Earth's surface?

• Atlantic Plate, Indian Plate, Arctic Plate

• Pacific Plate, South American Plate, Indian Plate

• Pacific Plate, North American Plate, Eurasian Plate, African Plate, Antarctic Plate, Indo-Australian Plate, and South American Plate

• European Plate, Asian Plate, Australian Plate

How does the movement of tectonic plates contribute to continental drift?

• It causes continents to drift apart or come together.

• It creates new continents

• It causes the Earth to stop rotating

• It has no impact on continental drift

What is the difference between convergent, divergent, and transform boundaries in the context of continental drift?

• Convergent boundaries occur when two tectonic plates move away from each other

• Divergent boundaries occur when two tectonic plates move towards each other

• Convergent boundaries occur when two tectonic plates move towards each other, divergent boundaries occur when two tectonic plates move away from each other, and transform boundaries occur when two tectonic plates slide past each other horizontally.

• Transform boundaries occur when two tectonic plates move towards each other

What are some of the effects of continental drift on the Earth's surface?

• Formation of mountains, earthquakes, and volcanic activity

• Global cooling, decrease in tectonic activity, and reduced seismic activity

• Rising sea levels, erosion, and desertification

• Increase in atmospheric pressure, expansion of oceanic crust, and decrease in volcanic eruptions

How does continental drift relate to the formation of mountain ranges and ocean basins?

• The movement of continents has no impact on the formation of mountain ranges and ocean basins

• Continental drift can cause the formation of mountain ranges and ocean basins through the movement of the Earth's continents.

• Continental drift is unrelated to the formation of mountain ranges and ocean basins

• Mountain ranges and ocean basins are formed by volcanic activity, not continental drift

What role does the theory of seafloor spreading play in the theory of continental drift?

• It provides evidence for the movement of the Earth's tectonic plates.

• It is a myth created by scientists

• It proves that the Earth is flat

• It has no role in the theory of continental drift

What are some modern technologies and methods used to study continental drift and plate tectonics?

• Telegraph and Morse code

• Compass and ruler

• GPS, satellite imagery, seafloor mapping, computer modeling

• Carrier pigeons and smoke signals
