Oceanography is the science of our oceans that mixes biology, geology, chemistry, and physics (among other sciences) to unravel the mysteries of our seas.
71% of Earth's surface is covered with water, so it is important we know something about the water surrounding us.
The Earth has an area of approximately 197 million square miles of which 140 million square miles is water. The Earth is broken up into hemispheres…Northern and Southern.
In the Northern Hemisphere, 61% is water and 39% is land, thus it is called the "Land Hemisphere".
In the Southern Hemisphere, 81% is water and 19% is land, thus it is called the "Water Hemisphere".
