It sustains us, surprises us, and holds mysteries we're only beginning to understand Dive into key topics here. Ocean acidification is a reduction in the ph of the ocean over an extended period of time, caused primarily by an increase of carbon dioxide from the atmosphere.

The solubility carbon pump, which stores much larger amounts of carbon, operates on timescales in the thousands of years and is a much slower mixing process. Without the ocean, life as we know it wouldn't be possible There are a number of key reasons why First, the ocean is the largest source of oxygen on earth
Most of this oxygen is created in the top 200 meters (656 feet) of the ocean's surface Within this depth, sunlight penetrates. What happens in the ocean as a hurricane passes over (courtesy nasa) hurricanes are the most powerful storms on the planet, spanning hundreds of miles (kilometers) We know them for the destruction they cause when they reach land Their high winds, heavy rains, and storm surges cause billions of dollars in damage each year.
Why is the ocean blue People have wondered this for hundreds of years One idea is that it reflects the sky From the coast, it may appear a deep blue on a sunny day Or gray when it's stormy Or even turn a brilliant pink during sunrise or sunset
Here, the water isn't reflecting the sky Ocean waters cover about 70 percent of the planet On average, that water is 3,800 meters (almost 2.4 miles) deep Extreme pressure is one reason why the ocean floor is still largely.
