In the water cycle, the step that shows how water moves from the biosphere to the atmosphere is when water evaporates into the atmosphere from the surface of a warming lake. This process is known as evaporation.
Here's a step-by-step explanation:
1. The Sun's heat warms the surface of the lake.
2. As the water molecules gain energy from the heat, they become more energetic and break free from the liquid state, turning into water vapor.
3. These water vapor molecules rise into the atmosphere, where they accumulate and contribute to the moisture content in the air.
4. Once in the atmosphere, the water vapor can condense to form clouds and eventually fall back to the Earth as precipitation, completing the water cycle.
Therefore, option D, "Water evaporates into the atmosphere from the surface of a warming lake," is the correct answer as it illustrates the movement of water from the biosphere (lake) to the atmosphere through evaporation.
