physical Geology quiz

toporgaphic maps

show the shape of the land by including elevation information

contour lines

third dimension is represented, lines of equal elevation

elevation

imaginary lines drawn to represent above datum

contour intervals

elevatin change between two lines is not a standard unit

fifth line

contour lines are not labed with on each line, but you will notice that each, is darker brown and is labaeled with an elevation

Index Contours

darker brown lines serves as a startting point when reading elevation

Benchmarks

elevations at specific points or features are marked with an “x” and the letters “BM”

relief

range of elevation represented by the contour lines on a topographic map

Gradient

measure of the steepness of a slope

Gradient math problem

slope rise/run

rule of “V”

states that there is a deflection of the contour lines on a map as they cross they valley produced by a stream
