Sea life

The term "sea" can be understood in a few different ways, but it generally refers to a large body of salt water. Here's a breakdown:
* General Definition:
* A sea is a large body of salt water.
* It can refer to the interconnected system of all the Earth's oceanic waters.
* It can also refer to specific, smaller bodies of salt water, often partially or fully enclosed by land.
* Key Characteristics:
* Salt water: Seas are characterized by their saline content.
* Vastness: They are large bodies of water, significantly bigger than lakes or rivers.
* Connection to Oceans: Many seas are connected to the global ocean, although some, like the Caspian Sea, are landlocked.
* Variability: Seas can vary greatly in size, depth, and characteristics, influenced by factors like geography, climate, and marine life.
* Distinction from Oceans:
* While the terms are sometimes used interchangeably, "sea" often denotes a smaller body of salt water, frequently a division of an ocean.
* Oceans are the major, interconnected bodies of salt water that cover most of the Earth's surface.
In essence, a sea is a significant part of the Earth's hydrosphere, playing a crucial role in regulating climate, supporting marine ecosystems, and facilitating global trade and transportation.
