Unformatted text preview: c ture 1: 1 Review of basic skills This PowerPoint presentation contains a review of the following topics: Scientific notation Unit conversions Maps, cross sections, and block diagrams Graphs and charts World geography For more information on these topics, Google the above phrases. c ture 1: 2 Scientific notation Which of these is the largest quantity? A. 150,000,000 kg B. 1.5x10 9 kg C. 3.5x109 kg The last two potential answers are in scientific notation, which is useful for dealing with very small and very large numbers, both of which are common in geology (see next 2 slides). The correct answer is B. In A, the equivalent number is 1.5x10 8 kg; in C, the negative exponent indicates a very small number. c ture 1: 3 Big numbers: sizes of natural features 10 4 =10x10x10x10=10,000 m 10 13 = 10,000,000,000,000 m c ture 1: 4 Small numbers: sizes of natural features 101 =1/10 1 =0.1 m 102 =1/(10x10)=0.01 m 109 =0.000000001 m c ture 1: 5 Scientific notation Powers of 10 Billion = 1,000,000,000.0 = 10 9 (giga) (G) Million = 1,000,000.0 = 10 6 (mega) (M) Thousand = 1,000.0 = 10 3 (kilo) (k) Hundred = 100.0 = 10 2 (hecto) (h) Ten = 10.0 = 10 1 (deca) (da) One = 1.0 = 10 Onetenth = 0.1 = 101 (deci) (d) Onehundredth = 0.01 = 102 (centi) (c) Onethousandth = 0.001 = 103 (milli) (m) Onemillionth = 0.0000001 = 106 (micro) ( ) Onebillionth = 0.0000000001 = 109 (nano) (n) Examples: A km is a thousand meters. A cm is onehundredth of a meter. c ture 1: 6 240,000,000,000. Scientific notation: large numbers Convert 240,000,000,000 to scientific notation. 1. Add a decimal point to the number to be converted. 240,000,000,000. 2. Count the number of decimal places from the current decimal point to that between the first two digits. 1 2 3 4 5 6 7 8 9 10 11 3. Use the number obtained in part 2 as the exponent in the scientific notation. Standard scientific notation places the decimal point between the first two digits. 2.4x10 11 c ture 1: 7 1.3000000 Scientific notation: large numbers Convert 1.3x10 5 to a conventional number 1. Add some extra zeroes to the number to be converted....
