describe the interaction between a water molecule and sodium chloride as it dissolves - The negative oxygen end of the water molecule is attracted to the positive sodium ion Which attributes of the water molecule arise from the unique bend in its geometry? - The hydrogen end has a positive charge, and the oxygen end has a negative charge. Why does the water molecule have polarity? - Water is geometrically bent to give one side, or pole, a positive charge and the opposite side a negative cha...

A tentative, testable statement about the general nature of a phenomenon is called a: - hypothesis What type of circulation occurs in a marginal sea where there is more evaporation than precipitation, causing inflow of ocean water at the surface and outflow of very salty water at the bottom? - antiestuarine circulation What was the earliest form of navigation? - dead reckoning You are in a ship at sea. Based on the position of the sun, it is local noon where you are. Your watch says it is 9...

The products of photosynthesis are carbon dioxide (CO2) and water (H2O). - False Compensation depth is the depth in the ocean where the photosynthetic rate exceeds the rate of cellular respiration. - False Tropical open ocean waters have the highest rate of primary productivity in the world's oceans. - False In primary production: - there is a net gain in organic carbon by organisms. In general, the rate at which energy is stored by organisms through the formation of organic matter is ca...

You are sailing on the ocean and you see the North Star (Polaris) appearing exactly half way between the horizon and a spot directly above you. You are: - at a latitude of 45 degrees N In order to be considered a scientific theory, an idea must be: - thoroughly testes over a considerable time period and be verified by many observations If you are at the coordinates 20ºS and 35ºE, where are you? - Africa How many 'named' oceans are there? - 5 You are at sea and observe that when the sun...

The tide-generating force is inversely proportional to the cube of the distance. - True There is no horizontal tide-generating force on Earth at points directly below and opposite the Moon. - True The barycenter follows: - a smooth orbit around the Sun. The difference between centripetal forces and gravitational forces is called the: - resultant force. t A If the resultant force has a significant horizontal component (tangential to Earth's surface), it produces tidal bulges on Earth, cre...

The surface tension of water - Is relatively high Which is the most abundant ion in seawater - Chloride Of the following statements about seawater salinity, which is/are true? - -The two most common dissolved components in seawater are sodium and chloride. (only option that starts with the) -Seawater salinity averages 3.5%. (both options with %) -Seawater salinity averages 35‰. All the following processes decrease the salinity of water except - Evaporation The ion in sea water that serv...
