what makes the tides go back and forth?

Answer 1

The gravitational pull of the moon.

Answer 2

The gravitational pull of the moon and the sun creates tides on the earth. While tides are most commonly associated with oceans and large bodies of water, gravity creates tides in the atmosphere and even the lithosphere (the surface of the earth). The atmospheric tidal bulge extends far into space but the tidal bulge of the lithosphere is limited to approximately 12 inches (30 cm) twice a day.
The moon, which is approximately 240,000 miles (386,240 km) from the earth, exerts a greater influence on the tides then does the sun, which sits 93 million miles (150 million km) from the earth. The strength of the sun's gravity is 179 times that of the moon's but the moon is responsible for 56% of the earth's tidal energy while the sun claims responsibility for a mere 44% (due to the moon's proximity but the sun's much larger size).

Due to the cyclic rotation of the earth and moon, the tidal cycle is 24 hours and 52 minutes long.

Answer 3

let me answer this. this is the most simplest question ok here we go.
at night the moon comes up then cause the moon has gravity it pulls anything towards it so the tides come forth then when the spins on its axis away from the moon we face the sun and the moons gravity is here anymore so the tides go back if u go to school u will notice you're science teacher will tell you this.

Answer 4

is the cyclic rising and falling of Earth's ocean surface caused by the tidal forces of the Moon and the Sun acting on the Earth. Tides cause changes in the depth of the sea, and also produce oscillating currents known as tidal streams, making prediction of tides important for coastal navigation (see Tides and navigation, below). The strip of seashore that is submerged at high tide and exposed at low tide, the intertidal zone, is an important ecological product of ocean tides.

Answer 5

the gravitational pull of the moon makes the tides go back and forth.

Answer 6

The Flying Spaghetti Monster

Answer 7

The Moon...and heres a story about it if youre interested...

On a far away plain stood five lonely statues.
Inside each statue lived a little fiend.
Every day they would come outside and marvel at their surroundings.
One day they each decided to take the one thing they liked best.
One took the sun,
One took the land,
One took the sky,
One took the sea,
One took the moon.
They stowed away their prizes in each of their statues,
and admired them.
But they soon realised that...
The sun could not stay up without the sky,
The sky was nowhere to be found without the land,
The land started to die without water from the sea,
The sea could not flow without the pull of the moon,
And the moon could not glow without the light from the sun.
So they decided...
...to put everything back.
And once again marvel at their surroundings.
The end

Hope that helps and that you enjoyed the story x

Answer 8

Gravity from the moon. The moon while in orbit, pulls back and forth(like it is trying to get away from the earth), causing waves.

Answer 9

Most people think just the moon, but the sun provides 50% of the tidal effect of the moon, or a third of the total.

Answer 10

The moon
