Document Summary
Build-up years decades months hours hours days millennia. Si standard for distance is meter (m) Atmospheric thickness= troposphere (bottom that has storms): 11 km; exosphere (top): 550 km. Ocean depth= average depth: 4 km; deepest portions (i. e. marinas trench): 11 km. Si standard for mass is kilogram (kg) Layering of materials according to density, materials are stratified into layers. Oceans can be classified by seawater density, available light, and ecological characteristics. Order of magnitude means power of ten : ex. Ubc van is an order of magnitude greater than the number of students in ubco- van has ten times more students than. Ubco (4000 ubc van= 40,000 ubco: ex. Ubco has an order of magnitude smaller than van- it has one tenth the enrolment. Return period: (time span of data record)/(number of cases of magnitude m) Octahedral: two square pyramids stacked bottom to bottom; 8 sides.
