Earth Science: Bill Nye Seafloor Spreading Video Worksheet
Directions: Watch the Bill Nye Seafloor Spreading Video at __http://www.youtube.com/watch?v=GyMLlLxbfa4__. Use the information provided in the video and your knowledge of Earth Science to answer the following questions. Use complete sentences for full credit.


  1. Until the end of the second world war, most scientists imagined the ocean floor to look like what? (2 points)
They imagined the floor to look flat.

  1. How many miles long is the mid Atlantic Ridge? (1 point)
It is about 12000 miles long.

  1. The average seafloor depth is about how deep? (1 point)
The average seafloor depth is 4-5 thousand meters deep.

  1. The mountains of the mid-Atlantic Ridge sit on average about how much higher than the surrounding seafloor? (1 point)
They are about 2 and a half kilometers apart.

  1. True or false: Harry Hess discovered that the age of the seafloor becomes progressively younger as it moves farther away from the mid-ocean ridge.

False.


  1. Hess discovered that molten lava erupted along the mid-ocean ridges, creating new seafloor. As the new seafloor formed, it pushed old seafloor away from the ridge. What term did Hess give to this process? (1 point)
He called it Seafloor spreading.


  1. The process that recycles the crust of the spreading ocean floor back inside the Earth is called what? (1 point)

It is called Subduction.

Continental-continental Convergent
both plates collide creates very tall mountains
Neither plate is able to be pushed down into the aesthesnosphere. There is a creation of very high mountains, folds in the crust, and an elevated plateau.
