Mechanisms and Evidences of Plate Movement

Which of the following does not describe the mechanisms of plate movements?

• The driving forces act in the same way as the resisting forces.

• The driving forces act against the resisting forces.

• The driving forces and resisting forces act antagonistically to influence movement.

Which of the following is the main force that fuels plate movement?

• ridge push

• mantle convection

• slab pull

• mantle conduction

Which of the following is true about mantle convection?

• The colder the rocks, the less dense it is so it rise.

• The hotter the rocks, the denser it is so it will sink.

• The colder the rocks, the denser it is so it will sink.

• The hotter the rocks, the less dense it is so it will sink.

Which of the following figures best illustrate ridge push?

• 
• 
• 
• 

The following are forces that drives plate movement except ____________.

• Slab pull

• slab push

• ridge push

• drag force

Which of the following best describes slab pull?

• The hot rocks in the mantle rise and cooler rocks in the crust sink.

• The subducting plate sinks into the hot mantle pulling the rest of the plate.

• The lithosphere is pushed up by the asthenosphere then gravity pushes the plate down the ridge.

Which of the following resisting forces opposes the slab pull?

• collisional resistance

• slab resistance

• transform fault resistance

in pushing the continental drift theory, Alfred Wegener presented similarities of which two continents?

• Asia and Africa

• Asia and Europe

• South America and Africa

• South America and North America

In searching for evidences of plate movement, in which region are the fossils of tropical organisms found?

• near the equator

• in polar regions

• under the ocean

Which of the following evidences does not support Wegener's claims?

• The shape of several continents seem to fit into each other.

• Animals in South America share common ancestors with those in Africa.

• Mountain ranges of different continents are made of the same rock sequence.

• none of these
