SCIENCE. Tides are another kind of wave motion in the ocean. variations in the salinity of ocean water. Definition. Since the lunar day is 24 hours and 50 minutes long and the earth rotates through two tidal bulges in that time, high tides will be spaced 12 hours and 25 minutes apart. The most common human health problems associated with red tides and other harmful algae blooms are various types of gastrointestinal, respiratory, and neurological disorders. Ocean currents can be caused by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes or storms. Services. Basically, tides are very long-period waves that move through the oceans in response to the forces exerted by the moon and sun. Tides are a large-scale ocean process that typically leads to the slow rise and fall of water level over a period of 6-12 hours. d. between neap tide and spring tide. Gravity is one major force that creates tides. Friction, drag, and density all come into play when describing the nature of a wave, the movement of a current, or the ebb of a tide. Q. wind; density differences. Answer (1 of 4): The moon position sets the nominal height and time of course. Cause and Effect: Tides. Tides vary in frequency, direction, and movement from place to place and from time to time. Why almost, because the time between two consecutive high tides is roughly 12 hours and 50 minutes. .. Rip currents are often incorrectly referred to as rip tides. A tidal bore is a large wave or bore caused by the constriction of the spring tide as it enters a long, narrow, shallow inlet. In a more complete analysis, tides are generated by forces imposed on Earth that are caused by a combination of gravity and motion among Earth, the Moon, and the Sun. Throughout the day the sea level is constantly rising or falling. Larger tidal range occur during spring tides (spring range), when the gravitational forces of both the Moon and Sun are aligned (at syzygy), reinforcing . the rise and fall of ocean water that occurs about every 12.5 hours. Red tides can be hazardous to human health and sea life.
