Short Answer:
About 97.5% of water on Earth is salt water and 2.5% fresh water.
More Information:
All of the oceans are salt water and the oceans represent more than 96% of all water on Earth.
Of the 2.5% fresh water, only 0.3% is in liquid form on the surface. Most of the rest is frozen or underground. Less than .01 % of all water is in lakes and rivers.
A breakdown of the various forms of water is as follows, going from the largest to the smallest.
96.500% Oceans, Seas, bays
1.7400% Ice caps, glaciers, snow
0.9400% Saline Groundwater
0.7600% Fresh groundwater
0.0220% Ground ice and permafrost
0.0070% Fresh Lakes
0.0060% Saline Lakes
0.0010% Soil moisture
0.0010% Atmosphere
0.0008% Swamps
0.0002% Rivers
0.0001% Biological
Fresh and salt water are very different for one key reason, fresh water doesn't contain salt and salt water obviously does. There are different flora and fauna in fresh and salt water for this reason.
Because marine fish live in salt water because there found in the ocean.
Fresh water (of the same temperature) has the lower density ('lighter').
just add salt to fresh water
Dissolving salt in fresh water.
because its the ocean ;D
Salt water freezes at a lower temperature than fresh water, so it typically takes longer for salt water to freeze compared to fresh water. This is because the presence of salt lowers the freezing point of water.
the majority of the world water is salt water, and about 3% of the worlds water is fresh but 2% of that water is glaciers. so that leaves only 1% of the worlds water supply

on fresh salt water
Salt water is much denser than fresh water and therefore can provide a much greater buoyant force.
Salt water is water that has salt in it and it is found in oceans. Fresh water does not have salt and is found in rivers and lakes.
salt water
Ocean water has a higher salinity (salt content) than fresh water does.
Because marine fish live in salt water because there found in the ocean.
Salt water is basically just fresh water with salt mixed in.
