Water is a chemical substance. A single water molecule contains two hydrogen atoms and one oxygen atom bonded together. The chemical formula for water is H2O. Water can be in one of three states. Water can be in a liquid sate, gas state (vapor) or solid state. An example of water in a liquid state is water in a lake. An example of water in a solid state is ice. An example of water in a gas state (vapor) is the steam coming off a boiling pot of water.

Water is the most important chemical substance on our planet. In fact, water is more important that oxygen. There are a few known organisms that don’t require oxygen, they’re known as anaerobic organism. However, all known organisms require water, whether consumed directly by drinking water or from water in the foods they eat. Without liquid water, life on our planet couldn’t exist. Water is an important resource on our planet that needs to be protected.

There is a lot of water on our planet. Around 71% of the Earth’s surface is covered in water. Most of the water found on Earth’s surface is in the oceans and seas. The water in the oceans and sea is saltwater and cannot be consumed by humans. Humans can only consume freshwater, like the water found in lakes, ponds, rivers and streams. In fact, 96.5% of the water on our planet is saltwater, only a small portion of it is freshwater.
