Not exactly. The Moon's gravity (together with the Sun's gravity) causes the tides on Earth.
Gravity for two reasons * The water moves from a higher region to a lower one (mostly for rivers) * The moons gravity causes high a low tide, this pull the water up then drop it causing the water to stir around in currents (this is mostly for oceans)
tidal currents
the gravity of the moon greatly affects the tides.
Then we would be in big trouble, because that would mean that there is no gravity.
Currents in the coastal water masses
Currents on the Earth are put into motion by the pull of the moon and gravity. Currents are important because they help to circulate the water in the oceans and seas.
The moons gravity pulls the water and makes high tide and low tide
The moons gravity 'pulls' the earths water creating a 'tide.'
Tidal currents are primarily caused by the gravitational pull of the moon on Earth's oceans. These currents result in the rising and falling of ocean water levels, creating high and low tides along coastlines.
The two causes of ocean currents are wind and the rotation of the earth(etc) The wind blows which makes the currents in the water and the rotation of the earth(gravity) makes currents in the ocean currents. Luaye Sharawy
gravity, water pressure, air pressure, buckets, etc.
Cold water currents are currents which flow deep along the ocean floor. Cold water currents can cause temperature changes which in return can have a major impact on the overall climate of the Earth.
