10. Ocean: Largest Solar Energy Collector
The amount of greenhouse gases in the Earth’s atmosphere is increasing, and as a result, these gases build up in the atmosphere and thicken its “blanket.” More heat is subsequently trapped.
The oceans also take in a significant amount of the extra heat that would otherwise remain in the atmosphere.
This process has been going on for a while, but as greenhouse gas concentrations rise, more heat is trapped, and a significant amount of that heat is making its way into the oceans.
11. Part of The Ocean That’s the Furthest from Land
The “Point Nemo” is a common name for the oceanic location farthest from any land. Ducie Island is the closest land mass, which is located roughly 2,688 kilometers away from it in the South Pacific Ocean.
It’s a far-off, barren place, and because of its isolation, it has come to be known as a “spacecraft cemetery,” where retired satellites and other space junk are frequently deorbited and allowed to burn up over this region to lower the risk of collisions with other space junk or with inhabited areas.
12. The Indian Ocean – The Most Dangerous for Sailing
The Indian Ocean is renowned for having difficult sailing conditions. It is dangerous due to erratic monsoon winds, abrupt storms, and powerful currents.
It is hazardous due to the Agulhas Current near southern Africa and the cyclone-prone waters of the Bay of Bengal.
To manage the complexities of these seas and reduce hazards, mariners need skill and meticulous planning.
13. Atlantic Ocean Has the Highest Tides
Contrary to popular opinion, the Bay of Fundy, a Canadian body of water connected to the Atlantic Ocean, has the planet’s most extreme tides, which can reach heights of 16 meters.

Frequently Asked Questions
How Does Ocean Acidification Work?
Ocean acidification is fueled by the atmosphere’s rising carbon dioxide (CO2) level. This CO2 is largely absorbed by the oceans, which causes a chemical process that lowers the pH of the seawater. Ocean acidity increases as a result. The extra CO2 combines with the water to create carbonic acid, which subsequently releases hydrogen ions to decrease the pH and increase the corrosiveness of the water.
What is the Great Barrier Reef?
The Great Barrier Reef, the world’s biggest coral reef system and a natural wonder, is situated in the Coral Sea off the northeastern coast of Australia. It consists of thousands of unique coral reefs and islands constituting a complex and lively underwater environment across 1,400 miles (2,300 km). It is possible to view the reef from space because of its size.
Why are Some Fish Called “Schools” of Fish?
When fish gather in huge numbers to swim together for various purposes relating to survival and protection, they are frequently called “schools.” These groups, or schools, may comprise hundreds to thousands of individual fish that move in unison. The schooling behavior of these aquatic animals has many benefits.
What Causes Waves in The Ocean?
The wind’s energy transferring to the water’s surface is the primary cause of ocean waves. The wind stirs up the water as it blows across the wide expanse of the ocean. The water molecules gain energy from this friction, which causes them to orbit in circles. These orbits produce waves that develop from ripples.
How is a Tsunami Caused?
The abrupt displacement of a significant amount of water, typically caused by undersea seismic activity such as earthquakes, volcanic eruptions, or landslides, causes tsunamis. Under the ocean’s surface, an earthquake can induce a rupture that shifts the bottom considerably. This movement causes the water above the fault line to move quickly, creating strong waves that travel in all directions.
