The Chemistry of the Earth

The world is full of variety. It is covered in trees, grasses, and leafy plants. The earth receives warm sunlight from above as the sun rotates in the constantly shifting sky. This is the everyday world that we see around us. This is the world that storytellers and poets write about. 

This world is also a world of chemistry. In this world, one form of matter is constantly changing into another. 

"We cannot always see it with our own eyes."

Nonetheless, it happens all the time. The earth's millions of living and non-living forms are all composed of roughly one hundred fundamental chemical elements. The same elements can be found everywhere. Only the combinations and quantities differ. This seems unbelievable, but it is true. It applies not only to the Earth but to the entire universe.
