Ocean depths, temperature, and Pressure Eric Angat Teacher

1. What are the seven spectra or color of light? Photosynthesis can only occur

1. What are the seven spectra or color of light? Photosynthesis can only occur where there is sunlight. 100 m depth is the limit of sunlight. Red, orange, yellow, green, blue, indigo, violet Red light cannot Green penetrate deep. light can penetrate a depth up to 100 m That is why corals are found in green colored ocean. Blue light can penetrate deepest.

2. Why is the color of the fish blue and black at a depth

2. Why is the color of the fish blue and black at a depth of 90 meters? Picture taken deep in Actual color, using a the ocean at 90 bright flasher, at meters or 295 feet. 90 meters or 295 feet. Because only blue and green colors can reach that depth. http: //disc. sci. gsfc. nasa. gov/education-and-outreach/additional/science-focus/ocean-color/oceanblue. shtml

3. What happens to the temperature as you go deeper into the ocean? Explain.

3. What happens to the temperature as you go deeper into the ocean? Explain. Y-axis is 0 m DEPTH 500 m (m) 1000 m 2000 m The temperature becomes colder the deeper you go into the ocean because less sunlight can reach deeper areas. Except 5 C X-axis is TEMPERATURE (C) 2324 2 C when there is an underwater volcano. C C

4. What are the layers of the ocean? 0 m 2000 m Surface layer

4. What are the layers of the ocean? 0 m 2000 m Surface layer -warm Thermoclinetransitional layer 3000 m 4000 m deeper 4000 m Bottom layer-cold

5. What happens to the pressure as you go deeper? Near Surface lowest pressure

5. What happens to the pressure as you go deeper? Near Surface lowest pressure Deepest highest pressure The deeper you go the more water is on top of you.

6. Why is sunlight ( heat) unevenly distributed on Earth? Because of Earth’s shape
