What do hachured lines show?

What are the rules concerning hachured lines?

What are the steps to draw a topographic profile place a piece of paper between the points mark where every contour line touches the edge of the paper determine the elevation of each mark place the paper on the graph and mark the elevation of each contour line

Using the map and chart below, construct a topographic map profile.

Please match the contour map on the left with the profile on the right.

The elevation of Albany is 282 feet. The elevation at Binghamton is 1634 feet. What is the gradient in feet/mile if they are 115 miles apart? gradient = change in elevation distance = miles = 1352 ft 115 miles = 11.8 ft/mile

The elevation of Watertown is 99m. The elevation at Oswego is 144m. What is the gradient in m/km if They are 75km away from each other? gradient = change in elevation distance = km = 45 m 75 km = 0.6 m/km

If the distance between the two circled cities is 425 km, what is the temperature gradient? Show all work. gradient = change in temperature distance = = = 0.08 °F/km
