KD2: Oceans

Sample Text - "Go up in a spaceship. Look at Earth. It is mostly blue. That's because almost three-fourths of Earth is covered by water. Some of the water is freshwater. It is found in rivers, lakes, and ponds. But most of Earth's water is in the salty oceans. Or should we say "ocean"? There are five oceans. But they are all connected. So it's really just one big ocean."
