Saltwater is not pleasant to drink, nor is it healthy. Saltwater actually makes you get dehydrated faster by drinking it. The amount of salt in the water causes your body to try to expel the extra salt. When it does so, some water accidentally gets expelled with it.
The ocean is important to life on Earth because it is the core of the water cycle. It also provides land creatures with food. The ocean also gives saltwater fish a place to live.

The Challenger Deep in the Mariana Trench is the deepest part of any ocean in the world at a depth of 36,070 feet. Most of the deep ocean is under pressures of 3000 to 9000 pounds per square inch. The average temperature of the ocean surface waters is about 17 degrees Celsius (62.6 degrees Fahrenheit). Deep ocean water has a very low temperature, typically from 0-3 °C (32-38 °F).
We gather many resources from the oceans, such as, oil, coral, fish (aquariums), fish (food), fish (decorations), salt, sand, gravel. Manganese, copper, nickel, iron, and cobalt can even be found in the deep sea
