2. General Units and conversions: Page xii, front of lab manual
Significant Figures in calculations:
3.0 * 120 = 360 2
3 * 120 = 400 (not 360) 1
3.178 * = (not ) 4
2.17 * 2,000 (Conversion factor) = 4,340 3
7.1 * 2,000 = 14,000 (not 14,200) 2
Many of your answers should have at least 2 significant figures, but no more than 3, even if not following the “rules”

16. What is the contour interval?
Page 242
Units of Elevation?
Units of Distance?
Contour Interval: difference in elevation between two adjacent contour lines (that are not equal).
What is the contour interval?
The location indicated by “x 108” is higher in elevation than 100 feet but less than 150 feet. If no listed elevation, what you predict it to be?
