Earth Science Practice - Long

What was the first significant evidence that supported the theory of Pangea?

• Fossil evidence of identical species

• Formation of ozone layer

• Ice age

Evidence for continental drift includes how similar the coastline is of these two continents:

• North America & India

• South America and Africa

• South America and Eurasia

why do the tectonic plates move?

• The tectonic plates move due to moon’s gravity.

• The tectonic plates move due to radiation.

• The tectonic plates move due to convection current.

Which of the following is a real world example of a hot spot volcano?

• Hawaiian Islands

• The Philippines Islands

• The Australian Island

Which of the following describes what happens at the mid-ocean ridge?

• Old ocean floor is dissolved

• New ocean floor is formed

The arrows show the movement of the plates. Which two tectonic plates form a divergent boundary?

• South American Plate and African Plate

• South American Plate and Nazca Plate

What type of landform would you expect to find at the South American Plate and the African Plate Plate Boundary?

• Mid-Ocean Ridge

• Trench

• Mountain

At an oceanic/continental convergent boundary the oceanic crust is forced under the continental crust. Why does this happen?

• The oceanic crust is denser, so it gets pushed under.

• The oceanic crust is denser, so it pushes the continental crust under it.

What type of stress is shown in the convergent boundary?

• shear stress

• tension

• compression

Arrows have been added to indicate the movement of the plates sliding past each other.

What crustal feature is being formed by this tectonic activity?

• A ridge

• A fault

• A mountain
