Only 53% of adults know how long it takes for the Earth to revolve around the Sun.

Trick question. The Sun and the planets and the stars are revolve around Earth.

# Only 59% of adults know that the earliest humans and dinosaurs did not live at the same time.

As if! Everyone knows that the dinosaurs never actually existed. God put their bones into the ground for us to find.

# Only 47% of adults can roughly approximate the percent of the Earth's surface that is covered with water.*

Okay, those other 53% are a bunch of doofuses.
Doofi.

The water coverage is also weasely. After all, Greenland and Antartica are both almost covered with water, though it often is ignored in these answers. Solid water, but water none the less.

Also, ALL water is "fresh"; just most of it is contaminated with disolved pollutants, most notably NaCl...but that is not part of the water, and can as easily be filtered or otherwise removed as some of the crud routinely removed from "fresh water supplies" before distribution.
