Oceanography Test 1 Study Guide Chapter 1: Knowing the Ocean World An Ocean World • Ocean creatures provide 2% of humanity’s food • 1/3 of the world’s petroleum and natural gas are pumped from beneath the ocean floor • ~ 71% world is covered by water • Ocean – vast body of saline water that occupies the depressions of the earth’s surface • 97% of the water on or near the earth’s surface is contained in the ocean; less than 3% is held in land ice‚ groundwater‚ and freshwater

in freshwater causes a decrease in density. I made three claims. First‚ the higher the salinity of the water is‚ the denser it will be. This was shown in my data by the fact that‚ with 0mL of fresh water‚ the density was 1.108 g/mL For every milliliter of fresh‚ pure water added‚ the density decreases by 0.015 grams per milliliter. I believe the density responded this way due to the fact that on average‚ seawater has a density of 1.025 g/mL. In this experiment‚ I added large amounts of freshwater (50mL

Chapter 6 Review Questions 1. Coral reefs are elaborate networks of crevices‚ ledges‚ and holes made up of calcium carbonate; coral polyps are tiny animals that build coral reefs by secreting a crust of limestone around their bodies that accumulate once multiple polyps die. Coral reefs help moderate atmospheric temperatures by removing CO2 from the atmosphere‚ act as natural barriers that help protect 15% of the world’s coastlines from erosion by battering waves and storms‚ provide habitats for

been produced however only some of those methods are widely used today. Although there are numerous methods of desalination all of them involve three liquid streams: the saline feedwater (seawater or brackish water)‚ low-salinity product water‚ and very saline concentrate (brine water). 1 The low salinity product water and the saline concentrate are output streams that are produced when the saline feedwater goes through the process of desalination.1 The desalination of the saline feedwater liquid

Lines of Latitude are parallel to the equator. True Lines of longitude are parallel to the polar axis. True What is the approximate diameter of Earth at the equator? About 8‚000 miles “Time” can be used to calculate latitude. False Why is it difficult to produce a 2-dimensional map of the earth that will faithfully reproduce to entire earth surface without distortion? There is no way to produce such a map because of the shape of the earth. According to Oceanography‚ Which of the following was the

Chapter 1 INTRODUCTION Background of the Study: For the past years‚ we‚ the proponents‚ noticed that the prices of products sold on stores keeps on increasing due to the unstable price of oil. We all know that life becomes harder and harder‚ and the products of our prime commodities and bills that we need to pay keeps on increasing. We also know that in our time today‚ we have to save money for our near future and for emergency cases. There are some ways to avoid spending too much money.

The restoration of the regions in San Francisco Estuary are based on many applications from water use‚ land use‚ dredging and waterway modification‚ wetlands management‚ and the pollution prevention and reduction fazes. I will be taking a look at the aspects of the pollution prevention and reduction within the San Francisco Estuary program. Estuaries are unique‚ dynamic transition zones‚ between the watershed and the world ocean system. In this paper I will try to discuss the abiotic and biotic

CHAPTER 6 PRETREATMENT AND CLEANING Pretreatment and cleaning are two independent processes that could also be related to each other at the same time. Such methods are crucial for seawater reverse osmosis for what they bring from cost and residence time reductions to the increase in the production quality. 6.1. Pretreatment Various pretreatment methods are used and they include: biofilter‚ subsurface intake systems‚ conventional treatment‚ biological activated carbon‚ and chlorine injection.
