  1. CRCT Question What are large flat plains located on the ocean floor? Trenches Mid-Ocean Ridges Guyots Abyssal Plains

  2. Corny Joke of the Day Why didn’t the car feel well? It had GAS

Work on Activity #3

  4. Activity #1

  5. Pros and Cons Concerns Some things were hard to read Some people did not follow the rubric There were some that had a lot of content missing Positives • Most of you were honest if you were missing some content • A lot of you did a great job with your creativity!

  6. Agree/Disagree The most abundant gas in the ocean is Hydrogen If there’s 1000 g of ocean water 3.5 of those grams would be salt Salinity is the amount of dissolved salt in water There are more gases at the bottom of the ocean Oceanographers use seismic waves to study the bottom of the ocean floor Volcanic activity is one way that salt is added to ocean water. Evaporation decreases the salinity of ocean water. Our test is next Monday

  7. How do we know what the ocean floor looks like? National Geographic “DRAIN THE OCEAN”

  8. Pick your Hat! Red Hat: What are your thoughts and feelings as your watch this? White Hat: Find important Facts and information Blue Hat: What questions to you still have after watching this Green Hat: What ideas for your project did you get from watching this? Orange hat: What facts did you already know?

  10. Mapping the ocean floor SCUBA-Self contained breathing apparatus. Makes humans able to breathe underwater Sonar-uses sound waves to map the ocean floor Submersibles-small vehicles that are designed for underwater exploration Satellites-used for temperature, salinity, storm tracker, etc.

  11. Ship using sonar and what it discovered. Sonar – (S0und Navigation and Ranging) Sonar tells us about the shape of the ocean floor by sending sound waves to the ocean floor and measuring how long it takes the energy to return. This tells us the topography of the ocean floor. Do you remember what topography is?

  12. Submersible craft are built to withstand deep ocean pressure. Often they are unmanned and have robotic "arms."

  13. Satellites

  14. Features of the Ocean Floor Shoreline – a boundary where the land and the ocean meet Continental margin – area where the underwater edge of a continent meets the ocean floor. Continental shelf – relatively flat part of a continental margin that is covered by shallow ocean water Continental slope – marks the boundary between the crust of the continent and the crust of the ocean floor.

  15. Abyssal Plains – large flat areas on the ocean floor. Seamounts and Guyots – scattered along the floor of the ocean are thousands of underwater mountains called seamounts. They are volcanic mountains that rise more than 1000 meters about the surrounding ocean floor. Flat top seamounts are called guyots. Trenches – the greatest depths found along the edges of the ocean floor Midocean ridge – mountain ranges on the ocean floor.

  16. Volcanic island

  17. Also called a seamount!

  18. Ocean Life Zones Intertidal zone – lies between the low and high tide lines. Hard for living things to survive. –where we swim! Neritic Zone – extends from the low tide line to the edge of the continental shelf. Rich in life. “Finding Nemo” Open-Ocean Zone – bathyal and abyssal zones, no sunlight, plants do not grow, little food is available, most animals are smallnear the bottom. Big animals in the open ocean
