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. During the moon's first and third quarter, periods of neap tides are experienced, due to the way in which the sun and moon act on the Earth to create tides.

Answer: Tides. most prevalent tidal type is semidiurnal, which is characterized by two high and two low tides per tidal day (lasting about 24 hours and 50 minutes). Wind is the primary force that causes ocean surface waves, but it does not cause the tides. Q. Rip currents are not tides, so this term can cause confusion. Tides vary in frequency, direction, and movement from place to place and from time to time. . Although the gravity pulls the land, only the water can move. At any given location on Earth, there are two high tides each day - one caused by the gravitational pull of the Sun, and the other by the gravitational pull of the Moon.

Tides are a change in the ocean water level, typically reaching a high and low level twice a day usually occurring about six hours apart. (1 point) when waves get bigger because of an approaching storm the rise and fall of ocean water that occurs about every 12.5 hours the rise of ocean water that occurs 12 . It occur when the moon is quarter. Because the centrifugal force is greater than the Moon's gravitational pull, ocean water on the opposite side of the Earth bulges outward. d. monthly tide. form due to the gravitational pull of the moon and Sun. During these tides, high tide is lower and low tide is higher compared to spring tides. Newton's law of universal gravitation states that the gravitational attraction between two bodies is directly proportional to their . a tide that occurs twice a month and results in the smallest change in sea level. a tide that occurs twice a month and results in the greatest change in sea level. During low high tides, the Earth itself is pulled slightly toward the moon, creating high tides on the opposite side of the planet. near the poles circling the equator around the .

Answer (1 of 3): original question: How does the ocean move to create tides? Rather, the term is derived from the concept of the tide "springing forth." Spring tides occur twice each lunar month all year long without regard to the season. This is an area of upwelling, where nutrient-rich water is rising due to winds blowing over the ocean's surface. By observing the Moon long enough from Earth, night after night . A type of harmful algal bloom, red tides refer to toxic blooms of microscopic algae that occur worldwide.
