For the same reason that people can jump up and down and planes can fly: power. Gravity is not of infinite strength. If it were, we wouldn't be able to do simple things, like raise our feet to walk or lift a book to read. Gravity is powerful enough to ensure that things don't float around, but it's not strong enough to prevent them from leaving the surfaces on which they rest if an adequate force is applied to them. Only a small amount of force or power is required to overcome the force attributable to gravity -- also known as weight. A swimming dolphin can easily produce enough power to generate enough speed to propel it through the surface of the water and continue through the air for a few meters. Thankfully, gravity is strong enough to ensure that what goes up must come down. Once the dolphin can no longer propel itself, it falls back into the ocean.
Their tail give them amaizing power.
They can jump in water.
Dolphins jump out of the water because they ar looking where they ar or they ar avoiding the preditors
all of them
No, dolphins actually do not "jump" out of the water but more propel themselves towards the top of the water at a rate such that the dolphin appears to be jumping. This is a common misconception.

Dolphins jump by swimming really fast. Once they have enough momentum they are able to propel themselves from the water which looks like they are jumping.
be one with the dolphins
Dolphins jump for MANY reasons, spinner dolphins for instince are very energetic and spin when they jump, they jump for fun, other dolphins may use this as a signal to other dolphins that they need help with catching sardines etc. Some dolphins jump because it is easy for them to look ahead when they are higher than the sea, they may use it for navigational purposes, sometimes just jump to express hapiness and their excitement, or they may jump because they are full of energy and want to play. Dolphins sometimes use it to communicate things to other dolphins, other times for hunting and some may jump for the sake of jumping. =)To breath or for people to see them.

I would not say they are not as talented but river dolphins tend to be more shy and not as enthusiastic as sea dolphins. You won't commonly see them jump out of the water and do tricks as you would see other dolphins do.
Because there stomach hurts so much.
