Did You Know?

The lithosphere is the solid surface of the earth (lith- meaning "rock"); the hydrosphere is the earth's water (hydro- means "water"), including the clouds and water vapor in the air; and the atmosphere is the earth's air (atmos- meaning "vapor"). The term biosphere can include all of these, along with the 10 million species of living things they contain. The biosphere recycles its air, water, organisms, and minerals constantly to maintain an amazingly balanced state; human beings should probably do their best to imitate it. Though the word has a new sound to it, it was first used over a hundred years ago.
