What Causes Ocean Tides Low Tide High Tide First Tide Second Tide Spring Tides Neap Tides

did you know that water ties are caused by the moon's gravity pulling on the earth hi everyone this is Mr and in this video we'll be learning about water tides when you go to the beach you probably notice that water is constantly moving in the ocean this is because high and low tides are caused by the gravitational force of the Moon acting on the earth within our solar system we know that the force of gravity keeps all planets orbiting around the Sun the Earth is constantly rotating on its axis and revolving around the Sun due to the Earth's gravity the Moon is also constantly rotating on its axis and revolving around the earth it takes the moon approximately 1 month or 27.3 days to complete one orbit around the Earth although the force of gravity on the moon is less than the earth because it is smaller in size its gravitational pool does have an effect on our Planet as the Earth rotates on its axis it faces the moon at certain times and the moon's gravitational force pulls on the earth this force causes water bulge in the direction of the moon this tidal Bulch causes sea levels to rise and is called high tide each day the Earth rotates into this bulge of water which is also known as the first high tide the second high tide or the Bulge on the far side of the Earth is caused by inertia the second high tide is result of counterbalance to the pull of gravity from the Moon you can also think of the earth as being squeezed and it bulging on both sides as the Earth rotates there are patterns in high and low ties throughout the day these patterns can also be seen during lunar cycle and both new and full moon there's an alignment of the Sun and the Moon to the Earth creating combined gravitational pool this combined pool causes the water in the earth to bulge more than usual causing higher Tides or what are known as spring tides it takes the moon 7 days after spring tide to orbit around the Earth and form right angle in its position to the sun this is when NE tides are formed in neep tide the gravitational pole of the Sun counteracts that of the Moon forming moderate Tides neep tides occur at the first and third quarter phase of the moon this is where the moon's orbit around the Earth is perpendicular to the sun it takes the moon approximately 1 month to complete one revolution around the earth this means that both spring tights and Ne ties occur twice in the lunar month let's review we just learned high and low tides are caused by the gravitational pull of the moon on the earth the first high tide is caused by the Earth rotating into bulge of water caused by the gravity of the Moon the second high tide occurs on the opposite side of the earth and is caused by inertia or by the Earth being squeezed spring tides are higher tids that are caused when both the Sun and Moon align in the force of gravity from both pools on the earth neep tides are moderate tides that occur 7 days after spring tide when the sun and moon form right angle to each other both spring tides and neep tides occur twice every lunar month
