The seven seas are a collective term used to describe the world’s major oceanic bodies, including the Atlantic, Pacific, Indian, Arctic, Southern, Mediterranean, and Red Seas. These vast water masses cover approximately 361 million square kilometers (139 million sq mi) of the Earth’s surface, accounting for about 71% of its total area.
Oceanography: An Overview
The study of oceans is known as oceanography. This interdisciplinary field combines biology, chemistry, geology, physics, and other sciences to understand the complex interactions between the sea, atmosphere, land, and living organisms. Oceanography explores various aspects, including the 7seacasino.ca formation and circulation of ocean currents, marine ecosystems, the global water cycle, and the impact of human activities on the oceans.
The Seven Seas: A Geographical Perspective
Each of the seven seas has unique geographical characteristics that define its ecosystem:
- Atlantic Ocean : The second-largest ocean, covering about 20% of the Earth’s surface. It separates the Americas from Europe and Africa.
- Pacific Ocean : The largest ocean, accounting for approximately half of the global water area. It lies between Asia, Australia, and the Americas.
- Indian Ocean : A smaller ocean but vital to world commerce due to its strategic location connecting Asia with East Africa and the Middle East.
