The ability to measure distances on a map will be very useful in later chapters as you learn how the agents that carve and
deposit landforms operate. The following exercises will help develop those skills.
(a) A river segment is shown on a topographic map as being 3.5 inches long. How long (in miles) is that segment if the
map scale is
1:24,000 1:62,500 1:100,000
(b) A stretch of shoreline is 20 miles long. How long would it appear on a map at a scale of
1:24,000 1:62,500 1:100,000
(c) What scale would you use to map a college quadrangle 300 feet long by 200 feet wide so that it fills as much as
possible of
●●
a 3″ 3 5″ index card?
●●
a 5″ 3 7″ index card?
●●
an 8½″ 3 11″ sheet of paper?
