Document Summary
Global temperature patterns have a major impact on earth"s landscapes. Temperature changes break down exposed bedrock and in uence soil development. Flora and fauna evolve within hot or cold conditions of climate. Matter is the stuff of the universe: solids, liquids, gases: has mass and volume. Internal energy: form of kinetic energy, energy of movement. ** temperature: description of average kinetic energy of molecules in a substance. *** heat refers to energy transfer from one object/substance to another due to difference in temperature. ***thermometers are instruments used to measure temperature. 3 main temperature global scales: fahrenheit scale: used exclusively in us, celsius scale: part of international system, kelvin scale: measures absolute temperatures, no negative values. Conversions: degrees fahrenheit= (degrees celsius x 1. 8) + 32 degrees. Monday, september 18, 2017: degrees celsius= kelvin - 273, kelvin= degrees celsius + 273. ** sun only signi cant source of energy for atmospheric processes.
