With the design of their flukes, also known as their tail fins, and dorsal fins a dolphin is able to jump out of the water. These fins are controlled by powerful muscles that allow the animals to leap out of the water and take in air that is needed for their survival.
The Orca (or Killer Whale) generates so much power with its flukes (its tail) that it can breach and completely clear the water with a minimal run up to the launch. Its flukes are moved up and down, as with all whales (and dolphins, which are a subgroup of the whales). == The animal dives down under water and using its tail (just as it does to move horizontally), it swims upwards as fast as it can. The generated momentum carries it up and out of the water. The Orca can launch itself completely clear of the water. It uses it powerful flukes and that "running start" to do this. Use the link to a short video of a Killer Whale. Then ask yourself how you'd like to be the kayaker in this little home movie. (The picture quality is quite good.)
it needs to swim down 100 feet in order for it to jump
Yes they do. But only some parts of the world.
they lift out of the water and...jump!
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.

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.
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.
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.

because the air provides less resistence compared to water. dolphins do it aswellBecause they can!
