Probably the most useful science that encompasses every other science, math, and engineering. Without it the water you drink would kill you or not be there (groundwater aquifers), the buildings we use would subside/crack/soil compress/liquefy/corrode/fail, just about anything wouldn't exist (what do you think steal, iron, copper, titanium, etc. are mined from?), there wouldn't be oil, natural gas, or coal (the world would stop), we would still think the Earth was 6000 years old, the environment would die, and a bunch of other things you wouldn't even think of would cease.

The study of solidified dinosaur poop spanning the worlds biggest urinal and extra terrestrial planets.

A pseudo-science that lies only a few steps above sorcery. Your typical geologist has his head up his ass and takes his field way too seriously.
