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) Until the second world war scientists imagined the ocean floor to look flat.

2.How many miles long is the mid Atlantic Ridge? (1 point)The mid Atlantic Ridge is 12,000 miles long.

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

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

5.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,it becomes progressively older.

6.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)The term that Hess gave to this process was Seafloor Spreading.

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

Oceanic-oceanic divergent
The plates come apart and the magma fill the gap.
The result is Mid-Ocean Ridges.

Pacific Ocean.
Oceanic-oceanic convergent
Two oceanic plates move towards each other. One is pushed down into the asthenosphere and begins to melt.
The result is trenches.

Aleutian Islands.
Continental-continental divergent
The plates move apart creates a rift valley can fill with water become an elongated sea.
The result is rift valley.

Great African rift valley. Baikal rift zone. Red Sea rift
Continental-continental Convergent
Both plates collide.
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.

Oceanic-continental convergent
The thin heavy crust goes under the continental crust.
The result is coastal volcanoes.
