This topographic map has two different contour intervals. What is the contour interval for elevations below 1000 ft.? What is the contour interval on this map for elevations over 1000 ft.? How would the upper elevations look if they had been mapped with the same contour interval as the lower elevations? How would the lower elevations look if they had been mapped at the same contour interval as the higher elevations? What is the scale of this map?
What will be an ideal response?
Over 1000’ the interval is 200’, under 1000’ the interval is 40’. The upper elevations would be too dark, the lower elevations would lack detail.

What is the difference between an active continental margin and a passive continental margin?
A) A passive margin is the site of an ancient continental rift, left behind when seafloor spreading moved offshore, whereas an active margin is an active plate boundary. B) An active margin receives large amounts of sediment whereas a passive margin is sediment starved. C) An active margin has earthquakes whereas a passive margin has quiet erupting (aka passive) volcanos. D) A passive margin is passively carried along by plate tectonics in a transform system, like the San Andreas whereas an active margin is a trench.
