A:Ocean tides are caused by the gravitational pull of the Moon and Sun. Due to the rotation of the Earth, locations will experience two high and two low tides each day. An alignment of the Sun and Moon will result in more extreme tides, known as spring tides.
A:Many factors impact the generation, severity, frequency and strength of ocean waves. One of the most important factors leading to the formation of an ocean wave is the wind. The shapes of the basins of the ocean dictate the ocean's regular movements and also affect waves.
A:Tides form when the gravitational forces of the moon and sun act on the Earth as it spins around its axis. Tides are the rise and fall of the sea level in reference to land. For example, spring tides are the result of the alignment of the sun, moon and Earth that typically occurs during new and full moons.
A:Tides, which are rising and falling sea levels, are caused by the effects of gravitational forces of the moon and sun combined with the Earth's rotation. Tidal magnitudes are affected by shoreline shape, the shape of bodies of water and environmental factors.
A:Tides are caused by a combination of three factors: the moon's gravity, the sun's gravity and the earth's own gravity. The moon's gravity is the most significant of these forces; it exerts 2.2 times more force on the tides than the sun's gravity does.
A:Tidal energy has been used since the early Middle Ages in Europe; no one person is credited with inventing it. The earliest record of communities using the power of waves to generate energy for paddlewheels dates from the 10th century.
A:When the sun heats the air, it causes the air to become lighter and float upwards. When hot air floats upwards, cooler air rushes in to take its place. The rush of the cool air against the water creates ripples, which eventually turn into waves.
A:Tides affect marine life by causing fish to gather in one spot, depending on the species and water depth. Strong tidal currents cause a concentration of bait and smaller fish that attracts larger fish to the area. Predicting tides is a tool fishermen use to improve their catches.
A:Waves break when the back of the wave moves faster than the front of the wave, causing it to spill over. The shape of a breaking wave is dictated by the shape of the ocean floor below it, with gentle slopes causing a gentle spill on a cresting wave.
A:High tide occurs on the side of the Earth that is opposite of the moon during orbit, while the side of the Earth closest to the moon experiences low tide. The gravitational pull of the Earth and moon causes high and low tide.
A:A spring tide is the tide which occurs at the time of full moon and new moon. The difference between the highest and the lowest rise of tides is highly pronounced during spring tide, and hence it can be easily distinguished.
A:Low tides and high tides occur as a result of gravitational forces between the moon and Earth. There is a gravitational force exerted on every object on the planet by the moon. The effect of the gravitational force is more apparent on bodies of water than it is on land.
A:Spring tides occur twice a month during the full and new moons. Spring tides are the result of the alignment of the Sun, Moon and Earth and the effects of their gravitational forces. Spring tides are also high tides.
A:The moon's gravitational force pulls water towards it, creating a high tide on the surface of the ocean closest to the moon. Also, the centrifugal force created by the Earth and moon orbiting around a central point creates a similar bulge on the opposite side, creating a second high tide.
A:Tidal energy is used to supply power plants with electricity. Tidal energy harnesses the power of water and the ocean in various ways. Very few commercial plants exist as tidal energy is still not widely in use.
A:The bottom layer of the ocean is the coldest because cold water has a higher density than warm water. The colder water sinks to the bottom of the ocean. This movement of water creates the ocean currents.
A:All tides, including the cycle of spring and neap tides, are caused by the gravitational pull of the sun and moon on Earth's ocean tides. Each month, the angles and alignment of the sun, moon and Earth work to influence the cycle of tides.
A:Tides, the periodic rise and fall in the levels of large bodies of water, are the product of gravitational forces. They result from the interaction of the Earth with both the sun and the moon, though the moon is the most significant influence year round.
