How far below sea level is the ocean floor?

The average depth of the ocean is about 12,100 feet . The deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam.

What is the maximum sea level rise that we Cannot safely exclude?

Even if the world follows a low greenhouse gas pathway, global sea level will likely rise at least 12 inches (0.3 meters) above 2000 levels by 2100. If we follow a pathway with high emissions, a worst-case scenario of as much as 8.2 feet (2.5 meters) above 2000 levels by 2100 cannot be ruled out.

What depth in the ocean would you expect to experience no sunlight?

Such a minuscule amount of light penetrates beyond a depth of 200 meters that photosynthesis is no longer possible. The aphotic zone exists in depths below 1,000 meters. Sunlight does not penetrate to these depths and the zone is bathed in darkness.

What’s under the ocean floor?

The ocean floor is called the abyssal plain. Below the ocean floor, there are a few small deeper areas called ocean trenches. Features rising up from the ocean floor include seamounts, volcanic islands and the mid-oceanic ridges and rises.

How many miles deep is the ocean at its deepest point?

7 miles
Then explain to students that the Mariana Trench is the deepest part of the ocean and the deepest location on Earth. It is 11,034 meters (36,201 feet) deep, which is almost 7 miles.

How high will the sea rise by 2030?

4 feet
Widespread areas are likely to see storm surges on top of sea level rise reaching at least 4 feet above high tide by 2030, and 5 feet by 2050.

Where can 90\% of the of the ocean’s life be found?

sunlit zone
Because photosynthesis occurs here, more than 90 percent of all marine life lives in the sunlit zone. The sunlit zones goes down about 600 feet. Many animals inhabit this zone. Most fish live in this zone.
