What Is It Like at the Bottom of the Sea?

When the sea appears on TV or in the movies, it always look endless. But do you know what it is like at the bottom of the sea? The seafloor along the coast is a beautiful world. There are flat sand beaches and hilly mountains. On the mountains, there are "forests". All kinds of fish and shrimps swim back and forth in the "forest" and mountains. On the sand beaches, there are also different kinds of strangely shaped animals either taking a walk or playing with each other. Things are quite different at the deep bottom of the sea. It is very dark and there is not even a single thread of sunlight. Yet, many fish and animals still live there.

Some fish even shine!

   flows from a higher place to a lower place rivers and lakes are deep valleys on the earth. The snow water and spring rain water from the mountins rain water and ground water all flow into the deep valleys. Gradually, the deep valleys become rivers. When the small ditches gather together. They become small river; and several small rivers will become a big one. When spring water rain and snow water

from all directions join, they form a river or a lake.
