Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon and the Sun and the rotation of the Earth. Tides are created because the Earth and the moon are attracted to each other, just like magnets are attracted to each other. The moon tries to pull at anything on the Earth to bring it closer. But, the Earth is able to hold onto everything except the water. Since the water is always moving, the Earth cannot hold onto it, and the moon is able to pull at it. Each day, there are two high tides and two low tides. The ocean is constantly moving from high tide to low tide, and then back to high tide. There is about 12 hours and 25 minutes between the two high tides.
What else can I help you with?
What causes daily high and low tides?
The moon and earths gravitational pull (gravity)
What is the stronger of the two forces that form ocean tides?
Lunar gravity.
What is a semi diurnal tide and how is it caused?
answ2. The tides are caused by the attraction of gravity.On the side of the Earth nearest the Moon, the attraction of the Moon lessens the strength of the local perceived gravity field.On the side of the earth farthest from the Moon, the ocean there sees the gravitational pull of the whole Earth-Moon system, but the effective centre of this system is further away than the real centre of the earth. Thus the gravity field is seen as slightly less and there will be high tides there as well.When the Sun and the Moon are in alignment with the Earth, (New Moon), we have the strongest gravitational force and the tides are at their maximum height.When the Sun is on the opposite side of the Earth from the Moon, (Full Moon) then we have a weaker gravitational force, and the high tides are not quite as high as for the New Moon case.
What kind of science studies waves currents tides acoustics and ocean atmosphere interactions?
Oceanography.
What are three reasons why you have tides?
# Free surface water # Masses in separate locations # The body with free surface water is rotating.
How many high tides and low tides do most locations in a ocean have daily?
Most locations in the ocean experience two high tides and two low tides daily. This is due to the gravitational forces of the moon and the sun causing the water levels to rise and fall in a pattern known as the tidal cycle.
What are daily changes in the elevation of the ocean called?
Tide is the answer.
What are the locations of high tides?
near the ocean
Daily rise and fall of the ocean waters?
It is called the tide, or tides.
What is the term for the daily rise and fall of ocean waters?
TIDES
What is the term for the daily rise and the fall of ocean waters?
TIDES
What are the daily changes in the elevation of the ocean surface are called?
The daily changes in the elevation of the ocean surface are called tides. Tides are primarily caused by the gravitational pull of the moon and to a lesser extent by the sun.
When are ocean tides experienced most?
Tides may be semidiurnal (two high waters and two low waters each day), or diurnal (one tidal cycle per day). In most locations, tides are semidiurnal. Because of the diurnalcontribution, there is a difference in height (the daily inequality) between the two high waters on a given day. Some of the greatest differences between high and low tides re found in the Bay of Fundy (eastern Canada).
Are ocean tides inexhaustible?
Yes, ocean tides are considered a renewable energy source because they are driven by gravitational forces from the moon and sun. As long as these celestial bodies continue to exert their influence on Earth, tides will continue to occur.
The periodic daily rise and fall of ocean water?
The periodic rise and fall of ocean water is known as the tidal cycle. It is caused by gravitational forces exerted by the moon and the sun on the Earth's ocean water, resulting in bulges of water that move around the planet as the Earth rotates. Tides typically occur twice a day, causing high tide and low tide.
Why do ocean waters keep on moving?
Because of the moon, controlling the tides
How often do tidesw occur on the Texas Coast?
because an ocean tide refers to the cyclic rise and fall of seawater.these tides are caused by variations in gravatational attraction between the Earth's ,moon and the sun ,in geometric relationship with locations on the Earth's surface.the reason that tides are periodic is due mostly to Earth's rotation being cyclical.
