The figure below shows ocean currents. Where will climate change slow the currents the most, causing colder temperatures, and why? Along the eastern side of South America, because increased temperatures will slow the movement of the Brazilian current and bring in cooler water Along the Kuroshio current, because it is carrying water north towards melting ice caps Along the N. Equatorial current, because climate change has its greatest effects at the Equator Along the northern coast of North America, because ice will melt in the Arctic and slow the Labrador and E. Greenland currents that travel south

Sally and sue were investigating the topic of friction in science. they used a small car and a ramp as seen in the picture to test what they were learning. they knew that they slipped easily on waxed floors but not on carpet, so they decided to change the material on the surface of the ramp to see what happened. they planned to use glass, carpet, aluminum foil, and sandpaper and run the car down the ramp over each surface. what would be the best research question to guide the girls' experiment? a) does the amount of surface area affect the friction on the moving car? b) will the car travel fastest on the glass surface? c) how does the angle of the ramp affect the speed of the car? d)do rougher surfaces tend to create more friction than smooth surfaces?
