The sea looks very pretty when the sun is shining on it. It can be very rough when there is a strong wind. The sea is very big. It covers three quarters of the globe! The sea is also very deep in some places. There is one spot near the Philippines , where the sea is about 11 kilometers deep. The highest mountain in the world is about 9 kilometers high.
