Question

What percent of the Earth's water is found in the atmosphere?

• A. $0.02$
• B. $0.001$
• C. $0.2$
• D. $0.003$

Answer 1

Answer: (B)

• The ocean holds about 97 percent of the Earth's water; the remaining three percent is distributed in many different places, including glaciers and ice, below the ground, in rivers and lakes, and in the atmosphere.
• At any given time only about 0.001 percent of Earth's water is in the form of atmospheric vapour, a surprisingly small number given its crucial role in weather.
