The ocean is filled with salt. (3.5%) If you have ever spent a day at the beach, then you probably know that the ocean water tastes much different than fresh water. It has a salty and almost dry effect in your mouth. This is because salt sucks moisture out of your body. We as living organisms drink water because our bodies need it, and because it tastes refreshing. If you were to drink salt water instead of fresh water, then the salt would suck all of the water out of your organs. This can result in death. There are many, expensive salt water filtration systems. It helps diminish the levels of salt in the water, making it safe for drinking purposes. Fresh water isn't as easy to find compared to saltwater. Most of the world is made up of oceans, but only 3% of the water is fresh.
The ocean effects all living organisms every day. It effects the rain patterns, the droughts, and even the food supply that some animals need. The tides, the circulation, and the currents, all play a large roll in your life. The sea-creatures call the ocean their home, the birds, their food supply, and the trees and plants, their water source. We all thrive because of the ocean and its many different purposes. The ocean can even change the path of one day. A sunny day could turn into a rainy one. A group of birds could get an extra meal due to the change in tides. The ocean is a very important aspect in our lives. It gives us a wide supply of food such as fish, octopus, crabs, lobsters, etc.
The ocean is related to the Earth's climate in many ways. The radiation from the sun soaks up water from the ocean. In the tropics, by the equator, the ocean acts as a giant solar panel, soaking up sunlight and reflecting heat. When the water molecules heat up, and take the form of a gas, evaporation happens. The water increases the humidity in the air and can bring storms as well. Almost all of rainfall on land has been impacted by an ocean. Ocean currents are a continuous flow of water in a certain direction. This can be influenced by wind patterns. The currents deliver the warm water, up towards the poles, and cold water, back down into the tropics.
When you travel far into the ocean, the water pressure rises, causing your eardrums to almost feel blocked. Animals in the ocean are built for high pressure situations. Their lungs can safely collapse if the pressure is too high. As the ocean gets deeper, the temperature also drops, due to the lack of sunlight and activity. There are many sea animals that can handle these cold temperatures, but others would simply die off. When the ocean gets deeper, the pressure rises and the temperature drops, causing all of the living things in those areas to adapt very differently.
