Floods usually occur when precipitation falls more quickly than that water can be absorbed into the ground or carried away by rivers or streams. Waters may build up gradually over a period of weeks, when a long period of rainfall or snowmelt fills the ground with water and raises stream levels. A flood may be really fast if the water is coming so fast that it runs rapidly off the ground. This is a flash flood. Positive effects – deposits new nutrient-rich sediments when they flood, helping farming. Floods also move large amounts of sediments which provide habitats for animals. Negative effects – can destroy homes, wipe out fields and crops, damage roads. 38. A well is created by digging or drilling to reach groundwater. When water is close to the surface, wells are convenient method for extracting water. They allow for access to water when no surface water is available. If too much water is taken, the ground may sink. The aquifer may no longer have enough water to supply the needs of the people. 39. Salt makes up 3.5% of the mass of ocean water. The salts are the ions chlorine, sodium, magnesium, sulfur, and calcium, among others. 40. The pull of the moon’s gravity on Earth causes tides. The sun’s gravity is a secondary cause. When the sun and moon are lined up with Earth, at either the full moon or new moon, the tidal range is greatest and the tides are spring tides. When the sun and moon are at 90-degrees to each other relative to Earth, the tidal range is least and the tides are neap tides. 411

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
