A Correct answer
Explanation

The percentage of freshwater available on the surface of land is $3$.
Freshwater makes up a very small fraction of all water on the planet. While nearly 70 percent of the world is covered by water, only 3 percent of it is fresh. The rest is saline and ocean-based. Even then, just 1 percent of our freshwater is easily accessible, with much of it trapped in glaciers and snowfields.

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Sunlight entering the water may travel about 1,000 meters into the ocean under the right conditions, but there is rarely any significant light beyond 200 meters.

The ocean is divided into three zones based on depth and light level. The upper 200 meters of the ocean is called the euphotic, or sunlight zone. This zone contains the vast majority of commercial fisheries and is home to many protected marine mammals and sea turtles.
