What is a scale?
scale of a map helps you relate the distances on the map to the larger, real-life distances.
What are the three map scales?
Fractional, verbal, and bar scales.
What is a fractional scale?
shows the ratio of the map distance to the real-life distance as a fraction.
What is a verbal scale?
expresses the relationship in words, for example, “ 1 centimeter is equal to 1 kilometer.”
What is a bar scale?
simply a bar drawn on the map with the size of the bar proportional to a distance in real life.
What is a relief?
the distance between a high and low place on a map.
Whag is an elevation?
the height of an object measured from a reference level such as sea level.
What is a sea level?
the average level of the ocean; the halfway point between hight tide and low tide.
What is a topographic map?
a map that uses contour lines to show elevation.
What is a slope?
a measure of how steep land is; also called gradient.
How do you draw a contour line and what does it look like?
Look on page 194.
What is a bathymetric map?
