what is the difference between a lake and a sea?

Answer 1

The sea isnt surrounded by land

Answer 2

There is no objective scientific distinction between the two. A sea can be a part of the ocean that has enough cultural significance to get a name, or an arm of the ocean such as a gulf or large bay. Sea can also refer to a very large freshwater lake, or to any size saltwater lake. Most geographical features were named a long time ago by people who knew little of the rest of the world, and weren't thinking of naming things according to any system.

Answer 3

I agree that a Lake is fresh water and a Sea is salt water. However, I would disagree that a sea is much larger than a lake. There are some large lakes out there: Victoria in Africa and Superior in USA, so I think it's best to concentrate on something that's more tangible than size.
Size is like color, it's a descriptor but not an answer that can be founded on actual information. Example, you can have a white rock, but you cannot determine what that rock is by the color. You'll have to look at other things like structure, shape, edting, and what it looks like under a microscope. Diamonds look like Cubic Zerconia until they're placed under a microscope and observed.

Answer 4

A lake is a body of fresh or salt water of considerable size, surrounded by land. A sea is the salt waters that cover the greater part of the earth's surface. So a sea is much larger and has different animals and fish that live in it too.

Answer 5

# 1 Lakes refer to a body of fresh water and a sea is a body of salt water

#2 a lake is surrounded by land, on all sides

#3 a lake is much smaller than a sea

Answer 6

LAKE

A lake is a body of water or other liquid of considerable size contained on a body of land. A vast majority of lakes on Earth are fresh water, and most lie in the Northern Hemisphere at higher latitudes. In ecology the environment of a lake is referred to as lacustrine. Large lakes are occasionally referred to as "inland seas" and small seas are occasionally referred to as lakes. Smaller lakes tend to put the word "lake" after the name, as in Green Lake, while larger lakes often invert the word order, as in Lake Ontario, at least in North America.

Most lakes have a natural outflow in the form of a river or stream, but some do not, and lose water solely by evaporation and/or underground seepage. They are termed endorheic lakes (see below).

The term lake is also used to describe a feature such as Lake Eyre, which is a dry basin most of the time but may become filled under seasonal conditions of heavy rainfall.

Many lakes are artificial and are constructed for hydro-electric power supply, recreational purposes, industrial use, agricultural use, or domestic water supply.

SEA

A sea is a large expanse of saline water connected with an ocean, or a large, usually saline, lake that lacks a natural outlet such as the Caspian Sea and the Dead Sea. The term is used colloquially as synonymous with ocean, as in "the tropical sea" or "down to the sea shore", or even "sea water" to refer to water of the ocean. Large lakes, such as the Great Lakes, are sometimes referred to as inland seas. Many seas are marginal seas, in which currents are caused by ocean winds; others are mediterranean seas, in which currents are caused by differences in salinity and temperature.

The International Hydrographic Organization (IHO) is the world authority when it comes to defining seas. The current defining document is the Special publication S-23, Limits of Oceans and Seas, 3rd edition, 1953. The second edition dated back to 1937, and the first to 1928. A fourth edition draft was published in 1986 but so far several naming disputes (such as the one over the Sea of Japan) have prevented its ratification.
