Pronunciation: [sˈiː wˈɔːtəz] (IPA) 
The spelling of "sea waters" follows the usual English rules for pluralizing nouns. The word "sea" ends in a vowel sound and the plural "-s" is added to form "seas." The word "water" ends in a consonant sound, so the plural "-s" is added to form "waters". In IPA transcription, "sea" is /siː/ and "water" is /ˈwɔːtə/. The plural "-s" is represented by the symbol /z/, making "sea waters" /siː ˈwɔːtəz/.
Sea waters refer to the salty or brackish body of water found on Earth's surface, covering approximately 71% of its total area. Formed primarily through the collection and accumulation of rainwater, sea waters are major components of the planet's hydrosphere. These vast bodies of water primarily consist of oceans, seas, and gulfs, and are crucial for sustaining marine life, regulating Earth's climate, and supporting various human activities.
Sea waters can be found across the globe, with oceans being the largest and most prominent examples. The seas and gulfs are smaller bodies of water that are partially enclosed by landmasses. The composition of sea waters is dominated by various salts, primarily sodium chloride, which gives them their characteristic salinity. Salinity levels can vary depending on factors such as proximity to freshwater sources and evaporation rates.
Sea waters serve as habitats for an incredibly diverse range of marine organisms, including fish, mammals, invertebrates, and various types of plants. These ecosystems are interconnected and play fundamental roles in maintaining global biodiversity. Additionally, sea waters act as enormous reservoirs of heat, absorbing, storing, and redistributing solar energy, thus influencing regional and global weather patterns.
Furthermore, sea waters provide a valuable resource for humans, supporting activities like fishing, transportation, trade, and recreational pursuits such as sailing, surfing, and swimming. International laws and organizations exist to address the management and conservation of sea waters to ensure their sustainable use for future generations.
The word "sea" originated from the Old English word "sæ", which can be traced back to the Proto-Germanic word "saiwiz". This Proto-Germanic term ultimately derives from the Proto-Indo-European root "*séh₂yos", meaning "lake" or "pond".
The word "water" comes from the Old English word "wæter", which has its roots in the Proto-Germanic word "*watōr". This in turn can be traced back to the Proto-Indo-European root "*wódr̥", meaning "water" or "wet".
When we combine these two parts, we get the term "sea waters", referring to the waters found in the sea or ocean.
