Question: 1 / 400

What is humidity?

a) A nuclear weapon that releases atomic energy by union of light (hydrogen) nuclei at high temperatures to form helium

b) Material formed from decaying leaves and other organic matter

c) Wetness in the atmosphere

Humidity is the measure of the amount of water vapor in the atmosphere. Option A is incorrect because it describes a nuclear weapon and option B is incorrect because it describes material formed from decaying organic matter, both of which do not relate to humidity. Option D describes hybrid offspring, which is also not related to humidity. Humidity is often associated with wetness, but it specifically refers to water vapor in the air rather than physical wetness.
