Plate Tectonics

What are the three main types of plate boundaries?

• Divergent, Convergent, Transform

• Hot, Warm, Cold

• Solid, Liquid, Gas

• North, South, East

Explain the process of seafloor spreading as evidence for plate tectonics.

• New oceanic crust is formed through volcanic activity and then gradually moves away from the mid-ocean ridges, providing evidence for the movement of tectonic plates.

• The process of seafloor spreading is a result of the Earth's magnetic field

• Seafloor spreading is caused by the gravitational pull of the moon

• New oceanic crust is formed through erosion and then moves towards the mid-ocean ridges

How do tectonic plates move at divergent boundaries?

• Tectonic plates move sideways at divergent boundaries

• Tectonic plates move away from each other

• Tectonic plates move towards each other

• Tectonic plates do not move at divergent boundaries

Discuss the impact of plate tectonics on the formation of mountains and earthquakes.

• Plate tectonics have no impact on the formation of mountains and earthquakes

• Mountains are formed by erosion, not plate tectonics

• Earthquakes are caused by volcanic activity, not plate tectonics

• Plate tectonics influence the formation of mountains through uplift and folding, and cause earthquakes due to the movement of tectonic plates.

Who proposed the theory of continental drift and when?

• Marie Curie in 1903

• Alfred Wegener in 1912

• Charles Darwin in 1859

• Isaac Newton in 1687

What technological advancements helped in the confirmation of plate tectonics theory?

• Seafloor mapping, seismic imaging, and GPS measurements

• Fax machines, typewriters, and pagers

• Satellite television, microwave ovens, and virtual reality

• Cassette tapes, VHS players, and rotary phones

What are the two types of plate boundaries where plates move past each other horizontally?

• Tensional boundaries and compression zones

• Divergent boundaries and subduction zones

• Transform boundaries and faults

• Convergent boundaries and rift valleys

Describe the evidence of fossil distribution to support the theory of plate tectonics.

• Fossil distribution across continents that were once connected

• Fossil distribution caused by volcanic eruptions

• Fossil distribution based on climate change

• Fossil distribution across different planets

What causes tectonic plates to move at convergent boundaries?

• Subduction

• Earth's rotation

• Global warming

• Volcanic eruptions

Explain the connection between plate tectonics and the formation of volcanic activity.

• Plate tectonics has no connection to volcanic activity

• Volcanic activity is a result of underground nuclear testing

• Volcanic activity is caused by meteor impacts

• Plate tectonics causes the movement of the Earth's lithosphere, leading to the formation of volcanic activity at plate boundaries.
