If I were a droplet and I was in the ocean. I would take a trip through the water cycle. The sun makes a energy to have me float up the air. Then I will travel through clouds and evaporate to the ground. Once im in the clouds you can go through the runoff or the groundwater. If I go through the runoff I will end up at the ocean that I started at. The groundwater will end up at the ocean where I started in the first place. Then I end up in the ocean I started at first.
