What is under the water in the ocean? Do you realize that there are trenches, mid-ocean ridges (mountains), and abyssal plains (flat areas with deposits of sediments)? Ask a fourth grader to show you their diagram and explain what is under all of that ocean water. Maybe they will also show you their diagram of the water cycle to explain precipitation, collection, evaporation, and condensation.
