Exploring the Ocean Blue

Challenger Expedition

Studying the Ocean Floor
  • The ocean is 3.8 kilometers deep on average.
  • Why do you think it is hard to study the ocean
    floor?
  • Darkness
  • Extreme Cold
  • Extreme Pressure

4
Technology
  • Sonar technology helped scientists study the
    ocean floor.

5
Lets take a trip to the ocean floor!!
6
We are going to start off the coast of Georgia
and travel to the coast of Africa!!
7
First we come to the
  • Continental Shelf
  • A gently sloping shallow area that extends
    outward from the edge of the continent.

Savannah
8
After that we reach the
  • Continental Slope
  • A steep slope.
  • This marks the true end of the continent.
  • Where the rock of the continent ends and the rock
    of the ocean begins.

9
Next stop on our list it the
  • Abyssal Plain
  • A smooth, nearly flat region.
  • Area covered with thick layer of mud and silt.

10
Dont run into the
  • Seamount
  • Under water mountains that can come above the
    ocean surface.

11
Watch out!!
  • Mid-Ocean Ridge
  • Continuous range of mountains.

12
Swim through the trench not over it.
13
Finally, we reach Africa!!!
  • We then come to a steep slope, then a gentle
    slope, and at last we are on shore in Africa!

14
Just a couple more questions!
  • What was the name of the steep slope we just went
    up?
  • What was the name of the gentle slope we just
    went up?
