3 - Tectonics Quiz

Scientists hypothesize that a super continent existed 200 million years ago.  This continent is called

• America
• Super Earth
• Pangea
• Eurasia

_______________ Currents within the mantle cause the earth's plates to move and shift s molten material rises and falls due to density and gravity

• Convection
• Radiation
• Conduction
• Wind

When pressure builds between two tectonic plates, it can suddenly release causing a (an) ______________________

• Earthquake
• Volcano
• Convection Current
• Gravitational Pull

In some areas of the world, like California and Japan, earthquakes are a common occurrence. How can this best be explained?

• The strong ocean currents are undermining both areas causing earthquakes.

• Both areas are located near the edge of the Pacific Ocean, the unstable sand causes earthquakes.

• Both areas are subjected to strong ocean wind and waves that causes earthquakes.

• Both areas are on the boundary of active plates, the motion of the plates causes earthquakes.

The map in the picture shows tectonic plate boundaries. This map would be useful in predicting the location of future

• droughts

• hurricanes

• earthquakes

• tornadoes

What is the correct order (starting from the surface) of Earth’s layers?

• crust, outer core, inner core, mantle

• mantle, outer core, inner core, crust

• crust, mantle, outer core, inner core

• outer core, inner core, crust, mantle

What are the two types of crust

• continental and oceanic
• ocean and upper
• lower and upper
• pizza and subway

During sea floor spreading, molten material rises up from the mantle...

• along the continents
• at the mid ocean ridges
• deep ocean trenches
• at north and south poles

What was Wegener's hypothesis called?

• The Pangea 
• Moving Continents 
• The Continental Drift
• Techtonic Plates

Why was Alfred Wegner's theory of Continental Drift not immediately accepted by scientists?

• there was no mechanism to explain how Continental Drift happened.
• The theory of Continental Drift was immediately accepted by the scientific community.
• there was no evidence to support his theory.
• Scientists did not think it was possible for the Continents to move.
