The deepest point on earth- The Mariana Trench
4 min readNov 22, 2021
- The oceans on earth are explored only 5%
- Globally, over 50 major ocean trenches are covering an area of 1.9 million km2 or about 0.5% of the oceans.
- The Mariana trench is the deepest point on earth.
- The deepest point in the Mariana trench is the challenger deep. named after the HMS challenger II.
- The pressure in the Mariana trench is 8 tons per square inch.
- It's 1000 times the standard atmospheric pressure.
- Mariana snailfish and the frilled shark are the famous creatures in the Mariana trench.
- Mariana's trench is 11, 034 meters deep or 36, 201 feet which is almost 7 miles deep.
- The Mariana trench is made up of 2 tectonic plates….. The pacific plate and the Philippine plate.
- The temperature in the Mariana trench is 34–39 F° it’s 1 to 4 degrees Celsius.
- The Mariana Trench occurs along a plate boundary between the Philippine Plate and the Pacific Plate. The Pacific Plate is on the eastern and southern sides of this boundary, and the Philippine Plate is on the western and northern sides of this boundary.
- It has vents bubbling up liquid sulfur and carbon dioxide, mud volcanos.
- Marine life adapted to pressures 1000 times that at the sea level.
- Simply no land creature can survive the pressure of the Mariana trench.
- The immense pressure will compress every area that contains air and will collapse the lungs and pressure will push water through the mouth and fill the lungs back with water.
- There is one place deeper than the Mariana trench. It’s the Kola superdeep borehole. It’s 9 inches wide and 12,262 meters deep. It’s simply unexplorable.
- It's 1300 meters deeper than the challenger deep.
- Challengee deep is approximately 36,200 feet deep.
- The pressure at the Challenger deep is like having 1800 elephants on your head.
- In particular, ocean trenches are a feature of convergent plate boundaries, where two or more tectonic plates meet. At many convergent plate boundaries, dense lithosphere melts or slides beneath less-dense lithosphere in a process called subduction, creating a trench.
- Sea monsters do lurk beneath the waves, scientists claim. From krakens to gigantic sea serpents, terrifying monsters of the deep have haunted the imaginations of generations of mariners. Now experts in marine life claim sea monsters might exist.
- Scientists think Cthulu (a fictional sea monster, mythic legend ) might exist in the Mariana trench.
- Sunlight simply cannot penetrate the thick layer of dust so the Mariana trench is covered in pitch-black darkness.
- Deep-sea creatures mostly rely on marine snow. (dead animals parts, dead plants, dust)
- A recent study revealed that a plastic bag, like the kind given away at grocery stores, is now the deepest known piece of plastic trash, found at a depth of 10,975 meters (36,000 feet) inside the Mariana Trench. While the Mariana Trench may seem like a dark, lifeless pit, it hosts more life than you might think.
- A nuclear submarine can dive to a depth of about 300m. This one is larger than the research vessel Atlantis and has a crew of 134. The average depth of the Caribbean Sea is 2,200 meters or about 1.3 miles. The average depth of the world’s oceans is 3,790 meters, or 12,400 feet, or 2 1⁄3 miles.
- From frightful fangtooth fish and vampire squid to coffin fish and spiky, sinister sea urchins, plenty of strange and scary creatures lurk in the dark, cold depths of the ocean. Be brave and dive on in.
- Trenches make only 0.25% of the oceans.
