  • “Earth is a unique planet, possibly one of the few in the galaxy that has water. Nearly 71% of it’s surface is ocean. From space, Earth is brilliantly blue, white in places with clouds and ice, sometimes swirling with storms. At it’s surface the ocean is in constant motion with powerful currents that stretch for thousands of miles and towering waves.
