Question

Sandra wakes up and finds the grass is covered with drops of water. It did not rain overnight, and her parents did not turn on the sprinkler. How did the water most likely get there?

Ice from a nearby pond evaporated and formed water drops.


Water drops were blown from a nearby pond onto the grass.


Water vapor from the air condensed when the air was cooled, forming liquid water.


Ice from the air melted into liquid water as it touched the grass, forming drops.

Answer 1

Water vapor from the air condensed when the air was cooled, forming liquid water.

At night the ground and grass cool; if their temperature falls to the dew point, water vapor in the air condenses on those surfaces as tiny drops (dew).
