Can the bottom of the ocean be reached?
But reaching the lowest part of the ocean? Only three people have ever done that, and one was a U.S. Navy submariner. In the Pacific Ocean, somewhere between Guam and the Philippines, lies the Marianas Trench, also known as the Mariana Trench. Challenger Deep is the deepest point of the Marianas Trench.
Could there be a deeper part of the ocean?
No. The Challenger Deep portion of the Mariana Trench remains the deepest point on the surface of the earth. Notice a trend? The deepest parts of the Earth’s oceans are all located in trenches associated with tectonic subduction zones (see Oceanic trench – Wikipedia ).
Could there be a deeper part of the ocean than the Mariana Trench?
Can we be sure that there isn’t a deeper spot somewhere? We can’t. Not absolutely. The Challenger Deep was first measured by the HMS Challenger expedition in 1875, a nearly 70,000-mile scientific voyage around the globe that laid the foundations for the modern science of oceanography.
Why can’t humans easily get to the bottom of the deepest parts of the ocean?
“The intense pressures in the deep ocean make it an extremely difficult environment to explore.” Although you don’t notice it, the pressure of the air pushing down on your body at sea level is about 15 pounds per square inch. If you went up into space, above the Earth’s atmosphere, the pressure would decrease to zero.

What is the deepest part of the ocean called?
The deepest part of our oceans, the region from below 20,000 feet to the very bottom of the deepest sea trench, is known as the hadal zone.
Is the Philippine Trench the deepest point on Earth?
The Philippine Trench is a submarine trench that is a narrow but long trench, lying in the east of the Philippine coast, in the western Pacific Ocean. It is also known as the Mindanao Trench, Mindanao deep of Philippine Deep. Until 1970, it was thought to be the deepest point of the earth.
What is the deep ocean floor most similar to?
True or False. The deep ocean floor is most similar in appearance and composition to the continental shelf. False New satellites allow the measurement of sea surface _____ with _____. topography, radar
How do scientists measure the depth of the ocean?
THE EXTRAORDINARY DEPTHS ARE MEASURED USING TNT. To measure the very deepest parts of the ocean, scientists use bomb sounding, a technique where TNT is thrown into the trenches and the echo is recorded from a boat, allowing scientists to estimate the depth.
