The Sea life

The term "sea" encompasses a few related concepts, but fundamentally, it refers to a large body of salt water. Here's a breakdown of its key aspects:
* General Definition:
* A sea is a large body of salt water, typically a part of the ocean that is partially or wholly enclosed by land.
* It's a significant portion of the Earth's hydrosphere.
* Relationship to Oceans:
* While often used interchangeably, "sea" and "ocean" have subtle differences. Generally, oceans are the largest saltwater bodies, and seas are often considered divisions of them.
* For example, the Mediterranean Sea is a sea connected to the Atlantic Ocean.
* Characteristics:
* Seas are characterized by their salinity, which varies depending on location.
* They are dynamic environments with currents, waves, and tides.
* Seas are home to a vast array of marine life.
* Figurative Usage:
* "Sea" can also be used metaphorically to describe a vast quantity of something, such as "a sea of faces."
In essence, a sea is a vital part of our planet, playing a crucial role in climate regulation, supporting diverse ecosystems, and serving as a pathway for global trade.
