Plate Tectonics

Front

What are the three main types of plate boundaries?

Back

Divergent, Convergent, Transform

Front

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

Back

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.

Front

How do tectonic plates move at divergent boundaries?

Back

Tectonic plates move away from each other.

Front

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

Back

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

Front

Who proposed the theory of continental drift and when?

Back

Alfred Wegener in 1912

Front

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

Back

Seafloor mapping, seismic imaging, and GPS measurements

Front

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

Back

Transform boundaries and faults

Front

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

Back

Fossil distribution across continents that were once connected

Front

What causes tectonic plates to move at convergent boundaries?

Back

Subduction

Front

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

Back

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