Oceans vs. Lakes

Oceans vs. Lakes

Let’s start with distinguishing which contains freshwater, and the one that contains saltwater. Lakes make up the 0.3% of freshwater we have on earth. The ocean makes up 97% of the saltwater here on earth. There are many different types of bodies of water  with the biggest being the ocean and the smallest being a brook.


Large bodies of saltwater that surround a continent. They have two key compound ingredients that make it salty, chloride and sodium. The ocean contains 99% of the living space on earth. That means that 50-80% of life on earth lives in saltwater. Oceans contain oysters and star fish. Our earth’s survival is centrally based off of the ocean’s water cycle. Our oceans also contain sand, while lakes do not. While oceans can also be significantly colder than lakes, and produce big waves. We distinguish oceans into four different ones, which are the Atlantic Ocean, Indian Ocean, Arctic Ocean, and Pacific Ocean.


Bodies of water surrounded by land all around. Therefore, they don’t have a specific size for lakes they can be small or large while still being smaller than an ocean. Rivers are what feed water to lakes, lakes can always change. Which can become dried out over time if the river stops producing water for the lake. You can find them in mountains or even hills. Although most lakes contain freshwater, hypersaline lakes, considered to be seas by some. Hypersaline lakes were part of oceans or seas, and because a tectonic shift were divided into their own lakes. These hypersaline lakes contain high amounts of salt. The ocean is blooming with marine life, lakes have few amounts of life under the surface. There isn’t as much aquatic life in lakes as there is in oceans, 100,000 species have already been discovered in freshwater.

When trying to distinguish the difference between a lake and the ocean the key things to consider would be the size, level of salt, location, and the amount of life prospering in each. While both are important to our earth, they both have different roles on earth.
