Difference Between Ocean and Lake

Earth is full of all kinds of resources from minerals like gold and silver to all the elements like carbon that makes up a lot of substances trapped beneath the earths ground from copper to all other substances these all can be found either lying in deep surface or in atmosphere or simply on the habitual surface.

Water is the resource that simply covers up to 70 percent of the earth’s surface and is found today in many forms like water, solid glaciers and liquated form.

Though the surface might be covered with 70 percent water but still many countries like Africa are dying of water scarcity and droughts making land infertile to grow crops it is because that 67 percent water that resides in ocean contains a very high amount of salt content that is unfit for any types of personal or commercial use.

Only 3 percent of water that is found underground and froze in glaciers is fit for drinking and many countries are in a constant race to obtain this and many countries today like gulf and south Africa is suffering from water scarcity leading people to die because of thirst and food shortage.

Ocean vs Lake

The main difference between ocean and lake is that the ocean is naturally made and are existing from the time of when the earth took birth they were formed when huge cracks developed between continents leading to oceans whereas the lake is a stagnant body that is manmade or it may occur naturally, moreover the ocean is a flowing water body whereas the lake is a still or a very little flowing body.

Ocean vs Lake

Comparison Table Between Ocean and Lake

Parameters of ComparisonLakeOcean
MeaningA lake is a stagnant water body that is small in terms of water. A lake is usually found between a habitual place used by locals like villagers where water might not be available.The ocean is a vast water body that contains at least 96 percent of Earth’s water that may not be fir for commercial or even personal use as the high salt content might cause health hazards.
NatureAll lakes might be naturally occurring, and many times, they are human-made for tourist attraction or welfare.All the oceans are naturally occurring and are residing for a very long time, changing their form.
SourceIt is a source of natural water for personal and agricultural use.It is a source of saltwater source used in many industries.
Opens Into?The Lake is a stagnant water body that is independent and does not opens further into a water body but is supplied through a lake.The ocean water opens up into much more significant and smaller rivers used for many purposes and is called distributaries.
Surface Area CoveredThe Lake is a tiny water body that is scattered at different places.The ocean covers 2/3rd of the earth’s surface.

What is Lake?

Lake is a stagnant or still with very a little movement water body that is used for many commercial but mainly personal purposes.

Lake is found between any habitation or people reside near the lake for the continues water source. Lake can be naturally occurring or it may be manmade for tourist attraction and fun activities like boating and rafting.

Lake contains abundance source of fresh water which is perfectly fit for human consumption as well as places where agriculture is the way of living.

There are many types of naturally occurring lake that is, tectonically lakes which are formed when a major earthquake takes place leaving deep cracks on the surface and it fills with water over time.

Second are the glacial lakes which are formed when glaciers melt and are found at cold places.

Ox bow lakes are formed when a very high-pressure flowing river cuts out from the main river due to pressure and forms a lake is called ox bow lake.

Lakes can also lead to many diseases like dengue and malaria if river keeps on getting polluted and slows down the water flowing leading to mosquito breeding.


What are Oceans?

Oceans covers all together 70 percent of earth surface and contains high amount of alt that makes it not usable for personal or commercial use.

Ocean is defined as the part that comprises of the hydrosphere and all world ocean that is Pacific Ocean, Artic Ocean, Antarctic Ocean, Atlantic and Indian ocean comprises and makes the world ocean.

The ocean gives birth to the most valuable and rare ocean species and plants moreover only 15 percent of ocean is discovered by the mankind.

Moreover, the ocean is divided by nautical miles by many countries in nautical miles and every country owns at least 11 nautical miles of the ocean and entry is probated that is constantly guarded by coast guard.

The deepest part in the ocean is the marina trench or the challenger deep found in between the Pacific Ocean that is 35000 feet below the ocean level and amount of pressure intolerable and can be withstand by human without special suit moreover it is a place where the most amazing species like sperm whale and blue whale are found.


Main Differences Between Lake and Ocean

  1. The ocean is a significant saline source or saltwater used for many purposes like trim level electricity production as saline water is a great conductor of electricity. In contrast, lake water, a tremendous freshwater source, is used for many personal uses like drinking, cooking, etc., and domestic use like agriculture and fishing on a tiny scale.
  2. The ocean water is not fit for commercial and personal use at it might negatively affect the body, whereas a lake is an excellent source of water. Still, these lakes might give birth to many diseases like dengue as the river water is stagnant, and no activity may lead to mosquito breeding.
  3. Ocean has a lower temperature because of very deficits in activities as the water remains untouched without a lot of sun rays touching. In contrast, the lakes have an increased temperature due to constant movement.
  4. Many species are found in the centre of the ocean, which is either used for consumption or selling purposes ocean also allows large-scale fishing. In contrast, a minimal number of species are found in the lake.
  5. Oceans are bottomless and can extend up to 35 thousand feet and a min range of 13 thousand, whereas the lakes are shallow and can extend up to a thousand feet.
Difference Between Ocean and Lake


All kinds of sources are found on earth and used for many purposes, whether commercial or even personal.

Water is found in abundance on earth and covers up to at least 70 percent of the earth’s surface with water. It can be found in a lot of forms like rivers, lakes, oceans, and ponds.

Ocean takes up to 96 percent of water, and only 4 percent is fresh and can be used for personal use. Oceans are used for transportation and large-scale fishing. Lakes are used for agricultural and personal use.
