Answer:
Salt
Explanation:
One of the key characteristics of the maritime environment is its high content of salt. This is actually especially true for the oceans, which cover about 71% of the Earth's surface.
The saltiness, or salinity, of seawater is due to the presence of dissolved salts and minerals, primarily sodium chloride (NaCl), but also including other substances such as magnesium, sulfate, calcium, and potassium.
Salinity is a crucial factor affecting the marine ecosystem, influencing the water's density, freezing point, and the biodiversity of marine organisms that can thrive in these saline conditions.
