Continental Drift
Pangaea animation
While the world is going to the present location India is moving faster and connects to Asia

1.In 1912 he proposed that the continents we know today were once all attached in a single landmass he called Pangaea.

2. The large super continent was Pangaea.

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)


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


  1. The average seafloor depth is about how deep? (1 point)


  1. The mountains of the mid-Atlantic Ridge sit on average about how much higher than the surrounding seafloor? (1 point)


  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.



  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)



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

Plate boundary notes

Grade:N/A
You will be creating a table for your notes on plate boundaries. You may cut and paste the table below to get started
Please cut and paste the following notes above your table:
Convergent: Coming together
Divergent: Coming apart
Transform: Moving parallel to each other
Oceanic crust: Thin but dense (heavy)
Continental crust: Thick but less dense (light)
Subduction: To move under another plate down into mantle

Oceanic-oceanic divergent
Plates that come apart magma fills gap.
mid ocean ridges, new crust

Oceanic-oceanic convergent
Two oceanic plates move towards each other. One is pushed down into the asthenosphere and begins to melt.
Creates trenches with the plates subducting each other.

Continental-continental divergent
Plates move apart to create rift valley can fill with an elongated sea.
They form a rift valley.

Great african rift valley. Baikal rift zone. Red Sea rift
Continental-continental Convergent
Both plates plates collide and creates very tall mountains and plateaus.
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 oceanic crust goes under crust as it goes down and rises.
This causes volcanoes.

Transform
Two plates sliding past each other.
This causes earthquakes and folds mountains San -Andreas fault
