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.

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

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?
