Question 10.5 pts
Please go to NASA's Scientific Visualization Studio and look at the first animation of Ocean Currents on this webpage.You are seeing ocean flow data. For this question, focus on the Pacific and Atlantic Oceans right around the equator. For the most part, in what direction are the ocean currents moving? Fill in the blank with the best answer. Equatorial ocean currents in the Atlantic and Pacific Oceans typically move from _________ to _________.
Group of answer choices
northwest to southeast
northeast to southwest
east to west
west to east
Flag question: Question 2
Question 20.5 pts
The second graphic on this website is a voiced-over animation about changes in the salinity of the Earth's
oceans. The video is about 2.5 minutes long. Please watch it, and then answer the following question. You are asked in this question to match a salinity feature shown in the animation to a cause. Group of answer choices
In much of the center of the tropical North Atlantic stretching from Africa to the Caribbean, this big area of high salinity is caused by __
Evaporation of water__________.
[ Choose ]
The patch of low salinity water in the Atlantic Ocean next to South America and right next to the equator
is caused by Fresh water coming_________.
[ Choose ]
The patch of low salinity water near the equator in the eastern Pacific Ocean (off the west coast of South
America) is caused by abundant rainfall that adds_________.
[ Choose ]
The patch of low salinity water just south of Greenland (Labrador Sea) along the far northeast side of North America is caused by the seasonal melting of ice_______________.

Flag question: Question 3
Question 30.5 pts
On this webpage from NASA's visualization center, the very first animation is voiced over by Greg Shirah. Greg is discussing the development of a model to predict where garbage will accumulate in the Earth's oceans. The model is validated by ocean buoys. Your question is simple: where does the garbage (and ocean buoys) collect after being moved around by ocean currents? This question requires that you first learned about the general circulation of the atmosphere along with the location of pressure belts.
Group of answer choices
In ocean gyres that tend to be centered under subtropical highs
Along the equator
In ocean low pressure centers that tend to be centered under subtropical highs.
In ocean gyres that tend to be centered under the intertropical convergence zone
