Earth Sciences 2240F/G Study Guide - Final Guide: James Hutton, Tidal Power, Uniformitarianism
Document Summary
Earth science short answers: uniformitarianism and catastrophism, uniformitarianism. The world came to be over time, did not believe in divine intervention, unlimited geological time, same natural processes that operated the world in the past exist today, scientific: catastrophism. Baron curvier: understanding geology under biblical constraints. H2 mass of 2 (nucleus has 1 proton and 1 neutron) H3 mass of 3 (nucleus has 1 proton and 2 neutrons: half-life= time it takes half the nucleus of an, earth internal heat and structure isotope to decay, -short/long-lived radioactive isotopes: heat by radioactive decay. Core formation heat: segregation of dense material to the core released gravitational potential energy. Once accretion melted earth gravity took over to separate heavies and lights. Dissipation of tidal energy: sun and moon raise ocean tides to slow earths rotation and recede moon, energy used to break the rotation is shown as heat: plate tectonics, convergent (compression), divergent (tension), transform (shear, subduction zones.
