A student set up a terrarium, watered the soil, covered the terrarium tightly with plastic wrap, and set the terrarium in a warm, sunny window. The next day, the student observed water droplets on the inside of the plastic wrap covering the terrarium. The water droplets provide evidence that which of the following steps of the water cycle had occurred in the terrarium?

A Runoff and evaporationRunoff and evaporation
B Evaporation and condensationEvaporation and condensation
C Precipitation and runoffPrecipitation and runoff
D Condensation and transpiration

Answer 1

The water droplets observed on the inside of the plastic wrap provide evidence that evaporation and condensation occurred in the terrarium. Evaporation happens when the water from the soil is warmed by the sun and turns into vapor, and condensation occurs as that vapor cools and forms droplets on the plastic wrap. Therefore, the correct answer is:

B. Evaporation and condensation
