The ocean is a dazzling, glistening sapphire blue. How did it get that color? Why is it darker in some parts than others? Is it a reflection of the sky, or is the sky a reflection of it? I was wondering those things when my family was driving in the car one day. Is it the pressure? Is it the minerals? Why do certain creatures flourish in specific environments where other creatures would die?
