Level 2 Continental Drift & Seafloor Spreading

The preserved remains or traces of an organism that lived in the past, which shows the continents used to be together.

• Evidence from Fossils

• Evidence from Mid-Ocean Ridges

• Evidence from Deep Ocean Trench

• Evidence from Subduction.

How are fossils created?

• A. Traces of organisms harden like rock. 
• B. Dead organisms are quickly buried for millions of years.
• C. Animals get trapped.
• D. All of the above

What does the theory of continental drift state?

• The continents were once joined in a super-continent and have moved over time
• Continents are stationary and do not move
• The Earth is broken into lithospheric plates that move due to convection currents
• none of the above

Who is the scientist who proposed Continental Drift Theory?

• Albert Einstein
• Alfred Wegener
• Isaac Newton
• John Dalton

What was the name given to all the continents when they were joined as one super continent? 

• Supreme Continent
• Eurasia
• Plate tectonics
• Pangea

This was a large, ancient landmass that was composed of all the continents joined together

• seafloor spreading

• continental drift

• Pangaea

• Eurasia

Which of the following is the corresponding oceanic land form for canyons? 

• Mountain 
• trench 
• plains
• mid-ocean ridge 

Younger sea floor crust is located...

• farther from the mid-ocean ridges
• at the mid ocean ridges
• at the subduction zone
• near the continents

Which landform is represented by letter A?

• continental shelf
• continental slope
• abyssal plain
• trench

On the bottom of the ocean, there is a mountain range that divides the ocean floor into two parts.  This area is also known as underwater volcanic mountains.

• continental shelf
• continental slope
• abyssal plain
• mid-ocean ridge
