Plate tectonics

What type of plate boundary is most likely to occur at point B?

• Convergent

• Divergent

• Transform

• Subduction

Which of the following is NOT included in the group in relation to the movement of the Eurasian Plate and Indian-Australian Plate?

• Rift Valley

• Mountains

• Mountain ranges

• Volcanoes (small)

How did the use of rock evidence support Wegener’s theory of continental drift?

• He noted that distant landmasses have rocks of similar age and composition.

• He checked that there are glacial evidence in the rocks.

• He said that rocks contain fossils that can be used for the study.

• He studied the composition of rocks and found that they have existed for a very long time.

What would one learn from a map of global earthquakes and volcanoes?

• where plate boundaries are found

• where most mountains are formed

• where edges of continents are found

• where seafloor spreading happens

Igneous rocks along the oceanic ridges are younger than the igneous rocks farther from the ridges. Which of the following best explains why this happen?

• the ocean floor is spreading

• the ocean floor is stable

• the ocean ridges are zone of subduction

• volcanoes once existed on both sides of the ridges

Read the following statements carefully. Choose the appropriate letter from the choices given below.

A – both statements are True

B – both statements are False

C – statement A is correct and B is incorrect

D – statement B is correct and A is incorrect

Statements:

(A) Convergence of two oceanic plates would result in the formation of undersea volcanoes.

(B) Convergence between an oceanic plate and a continental plate would result in the formation of volcanoes.

• A – both statements are True

• B – both statements are False

• C – statement A is correct and B is incorrect

• D – statement B is correct and A is incorrect

Which of the following statements does NOT infer why the theory shown in the diagram below was not widely accepted in the 1920’s?

• The proponent could not explain how the continents moved.

• The proponent was not a geologist.

• The proponent suggested that the continents moved at a very rapid rate.

• The proponent found fossils of tropical plants in the Arctic and Antarctic polar regions.
