Seawater: Don't Drink The Water!

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.

Why The Ocean Is Important To Life On Earth

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.

How Ocean Current Is Related To The Earth's Climate

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.

Zones Of The Ocean

The ocean is made up of many different zones, the Sunlight zone, the Twilight zone, the Midnight zone, the Abyss and the Hadal zone. The sunlight zone is the uppermost level of the ocean. It is bathed in sunlight during the daytime. It's the brightest layer of the ocean. It gets the most abundant sunlight, resulting in a lush variety of plants. Some of the animals that live in this zone include, sharks, manta rays, sea lions, seals and sea turtles. The zone falls between 0 and 656 feet. The second zone, the Twilight zone, is dimly lit, because the sun's rays can't travel that far. No plants grow in this region of the ocean because very little sunlight reaches it. Some of the animals that live here are octopuses, squid and jellyfish. This zone falls between 656 and 3,280 feet. The third zone, the Midnight zone, doesn't receive any sunlight. Some of the sea-creatures found here have weak vision or no eyes at all. They include Viper fish, angler fish, snipe eel and tripod fish. This zone is located between 3,280 and 13,123 feet. The fourth zone, the Abyss, (this word also describes the deep sea itself) is a zone far down in the ocean. The creatures living here lack bones including the backbone. One strange animal with this condition is called a sea spider. Others are called blind shrimp and hag fish. The Abyss is located between 13,123 and 19,685 feet. The last zone of the ocean is called the Hadal zone. Depths at this rate are commonly found in canyons and deep-water trenches. The temperature of this zone is just above freezing, causing only very little live to reside here. This zone is located between 19,685 and 36,197 feet.

Pressure, Temperature And Ocean Depth

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.

Resources The Ocean Provides For Us

The ocean provides many, many things that we use on a day-to-day basis. We use the oceans waters to transport us from different continents, ship our food to stores, get ingredients for medical reasons including medicine, and in many other ways. Some ingredients found in cancer, Alzheimer's and Arthritis medication are from the ocean. The ocean also produces 50% of the world's oxygen. The ocean plays a very big role in each of our lives.
