Document Summary
Microbialites: reef like sedimentary structures composed of calcium carbontate. Matter cannot be created or destroyed, it just exists in different states. Element= fundamental type of matter with set properties. Atoms= smallest components that maintain chemical properties. Isotopes: atoms with a different number of neutrons. Water is essential to life on earth. In any aqueous solution a small number of molecules dissociate or split apart each forming an either a hydrogen ion h+ or hydroxide ion oh- Energy conversion efficiency: ratio of useful energy output to the amount needting to be input. Photoautotrophs turn light energy from the sun into chemical energy (photosynthesis) 3 types of plate boundaries: divergent, convergent and transform. Pacific belt/ ring of fire most active area. Landslides= mass wasting, downslope movement of sediment as a result of gravity. Tsunamis: swell of water caused by one of the previous mentioned phenomena. Life evolved from a primordial soup of simple inorganic chemicals dissolved in surface waters.
