Sounding the sea!

The  ocean floor features can be measured and mapped using current acoustical technology? yes they can because you can use sand waves. Commercial and military industries can both use ocean floor maps by utilizing the ocean floor.
A flat abyssal plain- is an underwater plain on the deep ocean floor, usually found at depths between 3000 and 6000 m.
An underwater seamount or guyot-  A guyot also known as a tablemount, is an isolated underwater volcanic mountain (seamount), with a flat top over 200 metres (660 feet) below the surface of the sea.
A continental shelf, break, slope, and rise- The continental shelf is the extended perimeter of each continent and associated coastal plain. Much of the shelf was exposed during glacial periods
A submarine canyon on the contential shelf- is a steep-sided valley cut into the sea floor of the continental slope, sometimes extending well onto the continental shelf.
the mid-ocean ridge - are geologically active, with new magma constantly emerging onto the ocean floor and into the crust at and near rifts along the ridge axes.
A trench and island arc-  is a type of archipelago, often composed of a chain of volcanoes, with arc-shaped alignment, situated parallel and close to a boundary between two things. A trench and island arc system.

Dancing Conitnental

  1. Sum up what you learned from the “Dancing of the Continents” activity.
  2. Integrate the above theories with your learning, using your own words.
  3. Consider how scientists of different disciplines share information.
  4. Write all of your thoughts in a cohesive, full, two-paragraph essay.

What I learned from the project is where the continents are going to break apart and drift back together. the different colors represent the different places that their called. scientists probably work harder and knowing that

What did i learn on the field trip

What i learned on the feild trip was that plankton can't swim and that they can grow to become 6-8 ft. So in Spongebob plankton can have a chance to get a crabby patty. We also learned how the plankton give fishes food and 60-80% of oxygen. We learned how that the numbers on the map are the depth of the ocean so if you are boating you dont want to go in the parts that are 20 ft or less. We also did some labs and found the temputure of the ocean and the chemial levels change and the acid rain can kill off animals and in the future there will be more jellyfish than fish because of the acsinic levels.
