The sea life

A sea is a large body of salt water. Here's a breakdown of what that entails:
* Salt Water:
* A key characteristic of seas is their salinity, meaning they contain dissolved salts. This differentiates them from freshwater bodies like lakes and rivers.
* Large Body of Water:
* Seas are extensive, often appearing boundless from the shore. They are significantly larger than lakes.
* Relationship to Oceans:
* Many seas are connected to the global ocean, acting as marginal or regional sections of it.
* However, some seas, like the Caspian Sea, are landlocked.
* Varied Characteristics:
* Seas can vary greatly in depth, temperature, and currents.
* They are home to a vast array of marine life.
* Usage of the word "sea"
* The word "sea" can be used to describe the worlds ocean, or a smaller portion of it.
* It can also be used to describe a very large amount of something, for example, "a sea of people".
In essence, a sea is a vital part of Earth's hydrosphere, playing crucial roles in climate regulation, supporting biodiversity, and facilitating global trade and transportation.
