Water has a different density so it carries the sound vibrations differently.
Do you know why your voice sounds squeaky with helium? Same reason, the helium allows the sound waves go faster than normal air - that's why your voice sounds higher because the sound is moving faster.

The denser the material, the faster sound will travel through it. Think of it as a vibration. Have you ever seen a crowd of people at a concert fall down? The energy travels much faster in a solid material.
By the way Applecore, helium doesn't make sound travel faster- it changes the wavelength and therefore frequency. Thats why it sounds squeaky when compared to oxygen (normally in lungs)

I think it's because there are no obstructions like grass, trees, bushes to reflect or absorb the sound waves. I have noticed this too. Also when looking through a telescope or binoculars over water the image is clearer because there are no "heat waves".

sound is carried differently over water because water is concentrated and the ions of water are stable, so they doesn't transfer the sound .so sound is carried differently over water.

Sound is a wave propagation. It moves differently at different medium due to density , viscosity, compressibility etc.

because sound bounces off water and is absorbed in water.

water travels faster in denser materials; liquids are faster than gases, such as air, and solids are faster than liquids
