When you look at Earth from the vast reaches of space, it looks like a blue marble. In the words of Carl Sagan, from his book, Pale Blue Dot, “That’s here. That’s home. That’s us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives.” Do you ever look up at the night sky and wonder what happens beyond the confines of this planet?
The earth is our home, but it has existed for much longer than the human race. Geoscientists study the earth — its composition, its irregularities, its structure — to learn more about its history, and to tell us its secrets. Geoscientists use their knowledge of geology, physics and chemistry to study the earth.
