A gulf is known as a part of the sea that is almost entirely surrounded by land, except for a single opening to enter or exit the land.
Gulfs are commonly formed when rocks collapse or if a piece of land sinks. Although there are quite a few gulfs in the world, there might be even more in a few decades to centuries, as the melting of ice sheets and icebergs over the world is causing the seawater levels to rise, leaving islands partially underwater.
When a piece of land or rocks collapses and forms a gulf, the water of the ocean will circulate in and out of it, making it seem like a little beach-like ocean.
One will never see a gulf form in just one go. Gulfs take a very long time to occur and can even take up to millions of years.
The four big gulfs of the world
#1 Gulf of Mexico
Gulfs are usually named after the cities that surround them, such as the biggest gulf in the world, the Gulf of Mexico. This gulf formed 300-million years ago due to a sinking seafloor. The gulf today is an extension of the Atlantic and a very valuable source for the catch of seafood, serving the United States.
#2 Gulf of Oman
Connecting to the Arabian Sea via the Strait of Hormuz, the Gulf of Oman also runs into the Parisian Gulf and borders both northern countries, Pakistan and Iran. On the south, it borders Oman, and on the west, the UAE.
#3 The Persian Gulf
Located in the western part of Asia, between the Arabian Peninsula and Iran, the Persian Gulf further extends into the Indian Ocean where it meets the Gulf of Oman.
#4 The Gulf of Aden
With some of the biggest gulfs located primarily in seas surrounding Arabian countries, the Gulf of Aden can also be found between Yemen and Somalia, in the Arabian Sea, where it connects with the Red Sea.
