Three students аre tаlking аbоut the best descriptiоn fоr most groundwater. Student 1: I think most groundwater is like water in large underground holes or caves. When we look at water on Earth's surface, it gathers in big pools, so I think it would be the same underground. Besides, there is not enough room in rocks for water to fit. Student 2: I think most groundwater is like water in a sponge. Water fills in lots of very small empty spaces within certain types of rocks, like sedimentary rocks. Caves do not exist in most places, so that can't be what most groundwater looks like. Student 3: Most groundwater comes from artesian wells that push the water naturally to the surface. With which student do you agree and why?
