Checkpoint 4 Review (units 7-9)

Which of the following provides evidence that the continents on tectonic plates have moved away from each other in the past?

• The compositions and thicknesses of rock layers vary at different depths.

• The frequency of volcanic activity is higher at the edges of tectonic plates.

• Ocean currents can be disrupted near the boundaries between tectonic plates.

• Fossils of the same plants and animals are found on widely separated continents.

How is this information significant to the theory of plate tectonics?

• The presence of the Mesosaurus is evidence that freshwater animals can swim across oceans.

• The presence of the Mesosaurus is evidence that continents are all made of oceanic plates.

• The presence of the Mesosaurus is evidence that these continents were once connected.

• The presence of the Mesosaurus is evidence that reptiles cannot survive plate movement.

Word bank: plant, fossil, land, continental drift, plate tectonics, water.

Be sure to add a comma then space after each word in sequential order.

Alfred Wegener developed a theory that the continents were once a single landmass, but separated over time. __________ evidence of the animal Lystrosaurus has been found in the same geological layer on the continents of Africa and Antarctica. These continents are now separated by major bodies of __________ . The discoveries of these fossils help to prove the __________ __________ theory.

Which of the following is an explanation on why magnetic striping in seafloor spreading is evidence that supports plate tectonics?

• Plate tectonics theory is the theory that describes all energy as neither created nor destroyed, but changed from one form to another.

• Plate tectonic theory is the theory that describes the Earth's lithosphere is divided pieces called “plates,” that glide over Earth's mantle through convection currents and seafloor spreading.

• Plate tectonic theory is the theory that describes all objects on Earth as being in motion and want to remain in motion unless an unbalanced force disrupts their motion.

• Plate tectonic theory is the theory that describes life's origin from the simplest living cell to the evolution of animal species.
