To determine which cup best shows the amount of water covering Earth compared to land, we need to consider the actual proportion of water to land on Earth. Approximately 71% of Earth's surface is covered by water, while about 29% is land.
Given this information, the best choice would be the cup where around 70% of the total filled area represents water and the remaining 30% represents land.
Without seeing the specific amounts in the cups, the correct answer would be the cup that visually reflects a similar ratio — a cup that has significantly more water than land.
If you have descriptions or visuals of the cups, I can help you analyze them to find the closest representation of the Earth's water-to-land ratio. Please provide that information if possible!
