Today we used the text books to learn about the ocean floor. We discovered different landforms that were on the ocean floor, such as: continental shelf, continental slope, abyssal plain, seamounts, rift valleys, and mid-ocean ridges.
We also learned about how we know about the ocean floor, since it is so hard to get to. Sonar , which is an acronym standing for sound navigation and ranging, bounces sounds off the ocean floor, which are timed. How long it takes for the sound to return can be used to calculate how deep the ocean is. Also, satellites are used to determine ocean depths.
We also read about underwater vessels, such as Alvin, Deep Flight, and Jason II and Medea.
