Cycles

In a science lesson, Rye sets up a solar still as shown. He pours dirty salty water into a wide bowl and places an empty clean cup in the middle. He covers the bowl with clear plastic and puts a small stone on the plastic above the cup, then leaves the whole setup in bright sunlight. After some hours, clean water drips into the cup. Which sequence of water cycle stages BEST explains how the clean water reached the cup?

Zheng Hao is cooking soup. He notices that when he covers the pot with a lid, water droplets soon form on the inside of the lid, and the lid feels warm when he touches it carefully. Using what he knows about the water cycle, which explanation BEST accounts for BOTH the droplets AND the warm lid?

Alexa wants to find out how the surface area of water affects the rate of evaporation. She used two containers, X and Y, with different openings. She put 100 ml of water in X and 200 ml in Y, and placed both in the sun. Why is her experiment NOT a fair test?

Ethan placed four identical beakers, each containing 200 ml of water, in different locations. In which location would the water evaporate the SLOWEST?

Most of the water in Earth's oceans is salty. However, the rain that falls in Singapore is not salty, even though much of it began as ocean water that evaporated. Which statement best explains why?
