After a rainy morning, a group of students noticed several puddles near the playground slide. When they returned to the playground later in the afternoon, most of the puddles were gone.

What most likely happened to the water in the puddles?

• The water was absorbed by the playground equipment.

• The sun warmed the water, causing it to evaporate.

• Wind blew the water away from the puddles.

• The water turned into snow.

Answer explanation

When the sun comes out after rain, it heats the water in the puddles. This causes the water to change into water vapor and disappear into the air, a process called evaporation. This is the most likely reason the puddles were gone.
