The Water Cycle
Water is needed to sustain practically all life functions on planet Earth. A single drop of this compound is composed of an oxygen atom that shares its electrons with each of the two hydrogen atoms.
The cycle starts when precipitation, such as rain, snow, sleet, or hail, descends from the sky onto the ground. Water that is not absorbed immediately from the precipitation is known as runoff. The runoff flows across the land and collects in groundwater reservoirs, rivers, streams, and oceans.
Evaporation takes place when liquid water changes into water vapor, which is a gas. Water vapor returns to the air from surface water and plants.
Ultimately, condensation happens when this water vapor cools and changes back into droplets of liquid. In fact, the puffy, cotton clouds that we observe are formed by condensation. When the clouds become heavily laden with liquid droplets, precipitation ensues.

  • D. To be surprised
Correct Answer: A

Rationale: The correct answer is 'A: To consist of.' In this context, 'composed' means made up of or formed by. The sentence refers to a single drop of water being made of an oxygen atom that shares its electrons with two hydrogen atoms. Therefore, 'composed' in this context signifies the idea of something being comprised or made up of other elements.
