GEOL 1001 Lecture 2: GEOL 1001 TEST 1 SG
Document Summary
Processes that occur on the surface and inside of the earth. History of the earth and the development of the earth. Study of deep time millions and billions of years. Slow processes andres fault (1cm/year movement speed) If we look at what chemical and physical things operate today, they also operated in the past. Example: figuring out how oil reserves form, make predictions as to where to drill. Tentative explanation for how or why things happen. We can either reject, accept, or modify our hypothesis. Agree best with what we can observe in nature. Oceans (evaporation) atmosphere (precipitation) land (rivers) repeat. Cover 71% of earth"s surface is oceans, which is 97% of water on earth. Geosphere surface to the center of the planet. Climate change (changes in the atmosphere) (heat earth) melt glaciers [hydrosphere] (drinkable water goes into the ocean) biosphere [polar bears no home] (more intense storms) geosphere (weather more) [lose beaches]
