Science news: appalachians are rolling mountains b/c they"ve e(cid:374)dured 700 my of being worked on; formed by converging plates (plate boundary was once there, but the land that has accumulated has pushed those mountains back) Nature: life discovery, 3. 7 m year microbial structures (during heavy bombardment stage) areas of active research. Clicker q: sun = 75/25 with hydrogen + helium; thermonuclear fusion produces helium by burning through hydrogen (2) cambrian explosion accelerated diversity of life; (3) san andreas is a transformation boundary: N. american and other plate sliding past each other horizontally. Chemical reactions, movement, just about every process of survival, reproduction, eating etc. Food we eat (photosynthesis or respiration), through cellular respiration broken down, used or stored for reserves. Breaking chemical bonds releases nrg (glucose and oxygen to carbon dioxide and water: respiration: The arrow represents where the energy for cellular work is obtained/released.
