Is it true that its been 100 years since anyone last went to the bottom of the mariana trench?

No. 100 years ago, the deep submergence underwater vehicles had not been thought about, let alone invented and used.

The mariana trench was most likely created by?
The Marianas trench is caused by the subduction of the western edge of, the Pacific tectonic plate beneath the eastern edge of the smaller Mariana Plate that lies to the west. Since the Pacific plate is the largest of all the tectonic plates on Earth, crustal material at its western edge has had a long time since formation (up to 170 million years) to compact and become very dense; hence its great height-difference relative to the higher-riding Mariana Plate, at the point where the Pacific Plate crust is subducted. This, in turn, results in a particularly deep trench.
What are facts about the mariana trench?
The Mariana Trench (or Marianas Trench) is the deepest known part of the world's oceans, and the deepest location on the surface of the Earth's crust. It is located in the western Pacific Ocean, to the east of the Mariana Islands. The trench is about 2550 km (1580 miles) long but has a mean width of only 69 km (43 miles). It reaches a maximum depth of about 11,034 meters (36,201 feet) at the Challenger Deep, a small slot-shaped valley in its floor, at its southern end.[1]Part of the Izu-Bonin-Mariana Arc system, the trench forms the boundary between two tectonic plates, where the western edge of the Pacific Plate is subducted beneath the small Mariana Plate. Because the Pacific plate is the largest of all the tectonic plates on Earth, crustal material at its western edge has had a long time since formation (up to 170 million years) to compact and become very dense; hence its great height-difference (which translates to water depth) relative to the higher-riding Mariana Plate, at the point where the Pacific Plate crust is subducted (is forced down beneath the other). This deep area, is the Mariana trench proper. The movement of these plates is also responsible for the formation of the Mariana Islands.At the bottom of the trench, where the plates meet, the water column above exerts a pressure of 108.6 MPa, over one thousand times the standard atmospheric pressure at sea level. Some creatures of the type normally encountered that could live at these depths are few, but some fish species, like the angler fish or other deep-sea fish, have been spotted in these waters.[
Megalodon still live?
Although science says there extinct they could still be out there since only 15 percent of our ocean has been discovered and they could be living in the deepest point in the ocean which is the Mariana trench, so they could still be out there.
When did marianas Trench Become a band?
marainas trench has been a band since 2001-present
Which is the deepest point in the Indian Ocean?
At the 'Sunda Trench' ( or Java Trench) the depth is 7,725 metres (25,340 ft).AnswerIn the Diamantina Fracture Zone, 1,125kms off Australia, in the South east part of the Indian Ocean, there is trench called the Diamantina Deep, which has been measured to 8,047 metres (26, 401 feet) deep, making this the deepest point of the Indian Ocean.
The official date of trench warfare?
Trenches have been used in war since ancient times, but trench warfare was a feature unique to World War 1, from 1914 to 1918.
Who is the rest of the band members in marianas trench and how old are thay?

What was the bullets striking a soldier's chest when he is on the trench board during the World War 1?
A trench board was used in trenches to keep soldiers from touching the water that normally settled on the bottom of the trenches during the rainy season.. I'm not sure exactly the answer to your question would be since i'm not sure why a bullet would be hitting a soldier in the chest if he is laying on the bottom a trench. I will give you some calipers for WWI guns that may be used inside a trench... however there are 70 different rifles and handguns so... i can't even be sure the few I give you is correct either. 7.62×54mmR for Rifles the Browning hand guns which are the most popular officers is a .32 caliper The Colt model M1911 which was popular with American officers was a .45 caliper and the Colt Model 1917 which is a .32 Caliper. The Germans used the Luger P08 also which is a 7.65mm round.
Can humans go to the bottom of the Mariana Trench?
As far as I am aware, only two people have ever reached the bottom of the Marianas Trench. Jacques Piccard and Donald Walsh dived to 10,915 meters in a navy bathyscaphe called Trieste on January 23, 1960. I don't think this dive has ever been replicated by any manned submersibles since.
What good did tanks do in world war 1?
WW1 they did next to nothing. They had weak armor, were easy to stop, and since they were new no one came up with anystrategic designs using them. but they were used to push forward a bit in the trenches since WW1 was a all trench warfare anyone who walked forward was mowed down and even weak armored tanks did better then a guy in a cloth shirt
What foodchain does watusi cow are in?
The bottom, since they are herbivores.
What is the deepest point in the ocean and what is it?
In the Western Pacific, south of Japan and north of New Guinea, and to the east of the Mariana Islands is the lowest elevation of the surface of the Earth's crust. Known as the Mariana Trench, the trench is nearly 1,580 miles (2,550 kms) long and 43 miles (69 km) wide, its deepest part is known as the Challenger Deep. Named after the Royal Navy ship, HMS Challenger that first sounded it back in December 1872 to May 1876, who recorded a depth of 31,614 feet, (9,636 metres).Subsequent expeditions have lowered and raised the depth. In 1951, another Royal Navy vessel also called Challenger reported the depth as 35,761 ft, (10,900 m).In 1957, the Russian vessel Vityaz reported a depth of 36,200 ft, (11,034 m).In 1984, the Japanese reported a depth of 35,840 ft, (10,924 m)Since then the National Geographic has published the maximum depth at 36,200 feet (11,034 metres) in 1995.Also in 1995, the Japanese reported a depth of 35,798ft (10,911 m). This is thought to be the most accurate readings.In June 2009, an American expedition reported the maximum depth of 35,994 ft (10,971 m).In 2010, the US Center for Coastal & Ocean Mapping measured its depth at 36,070 ft (10,994 m).So if we take the 1995 Japanese readings as the most accurate, that is 6.78 miles (10.91kms) straight down. If Mount Everest was placed there, its summit would still be one mile below the surface. The pressure down there is a staggering 15,966 pounds (7.24 metric tonnes) per square inch, or roughly 1,086 times the pressure we live with at sea level.More men have walked on the Moon's surface than have visited the bottom. As of the time of writing (December 2009) only two men have visited the bottom, and that was back in 1960. Don Walsh and Jacques Piccard rode the bathyscape Trieste to the bottom, where they remained for 20 minutes. It looks like that record will stand for a long time, as no one has a manned DSV (that is in the public's knowledge) capable of reaching those depths.Yes, the Mariana trench is the deepest trench, also not to be rude but it's trench not treanch.
