Plate Tectonics Theory Quiz

Who first proposed the theory of Continental Drift?

• Harry Hess

• Alfred Wegener

• Arthur Holmes

• Marie Tharp

What was the main evidence Alfred Wegener used to support his Continental Drift Theory?

• Distribution of fossils

• Ocean floor mapping

• GPS data

• Satellite images

What theory did Harry Hess propose to explain the mechanism behind Continental Drift?

• Plate Tectonics

• Seafloor Spreading

• Subduction Zones

• Mantle Plumes

Which of the following is NOT evidence for the theory of plate tectonics?

• Matching shapes of continents

• Similar rock formations across continents

• The constant size of Earth

• Fossil distribution across continents

Paleomagnetism provides evidence for plate tectonics through the study of:

• Magnetic fields in rocks

• The temperature of the mantle

• The composition of the ocean floor

• The movement of the magnetic north pole

What role do convection currents in the mantle play in plate tectonics?

• They cool down the Earth's core

• They cause the plates to move

• They are responsible for the magnetic field of Earth

• They create volcanoes

Mid-ocean ridges are important in the study of plate tectonics because they are:

• Sites of deep-sea trenches

• Locations where new oceanic crust is formed

• The deepest parts of the ocean

• Areas where oceanic crust is oldest

Which type of boundary occurs when two tectonic plates move away from each other?

• Convergent boundary

• Divergent boundary

• Transform boundary

• Subduction zone

The presence of the same fossil species on continents that are now widely separated supports the theory of:

• Seafloor spreading

• Continental drift

• Subduction

• Mantle convection

What is the significance of the discovery of ancient glacial deposits in tropical regions?

• It proves that the Earth was once entirely covered in ice

• It supports the theory of seafloor spreading

• It suggests that continents have moved over geological time

• It indicates that the climate has not changed over millions of years
