how deep is the mariana trench?

Answer 1

Did you even TRY a simple search?

Answer 2

35,838 ft/10,923m (this is called Challenger Deep...the deepest part of the trench)

The trench is the boundary where two tectonic plates meet, a subduction zone where the Pacific Plate is being subducted under the Philippine Plate. The bottom of the trench (Challenger Deep) is farther below sea level than Mount Everest is above it. The trench has a maximum depth of 10,911 meters (35,798 ft or 6.78 miles) below sea level. Taking into account its latitude and the Earth's equatorial bulge, this puts it at 6,366,400 meters (3,955.9 mi) from the center of the Earth. The Arctic Ocean, on the other hand, is about 4,500 meters (14,800 ft) deep, which would put its floor at 6,353,000 meters (3,947 mi) from the Earth's center, some 13 kilometers (8.5 mi) closer.

The Mariana Trench is located in the Pacific Ocean, just east of the 14 Mariana Islands (11"21' North latitude and 142" 12' East longitude ) near Japan. As you probably already know, it is the deepest part of the earth's oceans, and the deepest location of the earth itself. It was created by ocean-to-ocean subduction, a phenomena in which a plate topped by oceanic crust is subducted beneath another plate topped by oceanic crust.

The deepest part of the Mariana Trench is the Challenger Deep, so named after the exploratory vessel HMS Challenger II; a fishing boat converted into a sea lab by Swiss scientist Jacques Piccard.

Facts: 35,838 ft. or 10,923 m straight down. It takes almost 5 hours to freefall all the way to the very bottom.

Answer 4

Depends on the rock you're bouncing your sonar off of.
