Geology is the foundation science. Pun intended.
It is the study of how everything we can lay hands on came to be. Geology draws from every investigative discipline – physics, chemistry, biology, anthropology and a lot more ologies – to examine the wheres, whens, and whys of mountains, water, and us.
But before a geologist can start to answer questions like “How did the planet form?” and “Where did bipedal apes come from?” she must equip herself with a few basic skills that will make gathering data and weighing hypotheses a little easier.
