The Scientific Study Of Earth Essay
Scientific method: the way a scientist approaches a problem; steps include observing, formulating a hypothesis, testing, and evaluating results
Hypothesis: a plausible but yet to be proved explanation for how something happens
Theory: a hypothesis that has been tested and is strongly supported by experimentation, observation, and scientific evidence.
Geosphere: the solid Earth, as a whole
Biosphere: the system consisting of all living and recently dead organisms on Earth
Atmosphere: the envelope of gases that surrounds Earth
Hydrosphere: the system comprising all of the Earth’s bodies of water and ice, both on the surface and underground
Hydrologic cycle: a model that describes the movement of water through the reservoirs of the earth system; the water cycle
Rock cycle: the set of crustal processes that form new rock, modify it, transport it, and break it down.
Tectonic cycle: movements and interactions in the interactions in the lithosphere by which rocks are cycled from the mantle to the crust and back; this cycle includes earthquakes, volcanism, and plate motion, driven by convection in the mantle
Lithosphere: Earths rocky, outermost layer, comprising the crust and the uppermost part of the mantle
Meteorite: a fragment of extraterrestrial material that falls to earth
Crust: the outermost compositional layer of the solid Earth; part of the lithosphere
Mantle: the middle compositional layer of Earth, between the core and the…
