Ocean depth is also an important factor in coral reef survival. Go to https://maps.ngdc.noaa.gov/viewers/bathymetry/ Click on Mercator (upper right) and check off "Multibeam Bathymetry Mosaic". Compare this map with the map that has the red dots that indicate coral reefs on the previous page. Answer question 5 on your worksheet. The map on the next page shows the current state of aragonite (calcium carbonate) saturation in the world's oceans. Saturation is the point at which a solution can dissolve no more of a particular substance and additional amounts of that substance will appear as a precipitate. However, you can sometimes get more solute to dissolve if you change the conditions (e.g increase the temperature of the solution). This type of solution is called supersaturated. Saturation level is represented by the Greek letter omega (Q). when ? # 1, the solution is saturated, and when ? >1, the solution is supersaturated, meaning that there is more calcium carbonate dissolved in the water than is possible under normal conditions. The

Explanation / Answer

1. The majority of coral reef are found within tropical and subtropical waters and occur between 30 degree north and 30 degree South latitude. Various species of corals are found in all krna of the world from topics to the polar regions. Proximity of reef to the land results in some terrigenous sediment input to coral reef islands and open sea reefs that surrounds the lagoon.

2. Environment condition required by coral reef is the clear water that let's the sunlight to pass through. Reef building require warm water to survive.

3. The optimum temperature for coral reef is between 23 degree Celsius to 29 degree Celsius.

4. Yes, the seasonal variation affect the health of coral reefs as they are very sensitive to the change in temperature.

5. About 300 ft coral reefs favor because of the sunlight reaching the water and allowing the photosynthesis.

8. By deposition of calcium carbonate the coral reefs are formed, and calcium carbonates are very important for the regulation of pH of the ocean water that surrounds them.
