What causes the sea water in and out momentum I know winds push the water inward towards the shore but what makes it go out again moments later?

Is the momentum of an object moving in a circular path at constant speed constant?
an object which moves in a circle must have a net inward force. There are many instances of individual outwards forces which are exceeded by an individual inward force ======================== In terms of an answer to the question . . . The magnitude of its momentum is constant. But momentum is a vector ... its direction is the same as the direction of the object's velocity. So the momentum vector isn't constant. Exactly the same reasoning as velocity in circular motion at constant speed.

Why is the world round not flat?
"Gravity is a centripetal force, it exerts its tremendous force inward, toward the center of gravity, always trying to form the Earth into a perfect sphere while the angular momentum is an outward tangential inertia (centrifugal force) that causes the oblate shape of the Earth." ~http://novan.com/earth.htm

Why are roads bent inward on curves?
Roads, particularly those that are designed for high-speed travel, tend to be inclined with the bottom at the inside of the curve and the top of the incline at the outside of the curve. This is to help the driver counteract the momentum of the car, which will tend to push the car towards the outside of the curve. Momentum is the tendency of an object in motion to remain in motion on a straight line course unless acted upon by an outside force. Because the car is turning away from the straight line to follow the road, a force has to be applied to move the car from the straight line to the curve. Inclining the road helps provide this force - it helps turn the car by allowing gravity to pull the car down the incline and towards the center of the curve and counters the pull of the car towards the outside of the curve via momentum. This is why, when driving at higher speeds, you have to be careful about how quickly you try to turn your car. If you try to turn faster than you can overcome the momentum of the car, you will flip the car sideways and start rolling it.

What is the source of centripital force that a planet requires to revolve around the sun?
The Sun's gravity is a force pulling the planet directly towards the Sun. That is always exactly balanced by the planet's acceleration, which is also towards the Sun. However the planet's momentum carries it forward in its orbit so the effect of the inward acceleration is to make the planet curve towards the Sun, and that is how the planet maintains its elliptical orbit. The above details were discovered by Isaac Newton and he was able to demonstrate why Kepler's laws of planetary motion are as they are. I won't get into centrifugal/centripetal because they are often confused.
