As you go, observe the elevation values and how they change across the width of the ocean basin. Is there a pattern to how the water depth changes as you move across ocean floor of different ages? Using Microsoft Words Draw feature, make a rough cross-section (i.e., elevational profile) sketch of the line traveled by your cursor, with America on the left and Europe or Africa on the right. Show the general topography of the ocean floor along your line, using the depth changes as a guide. 4. Note: your sketch doesnt need to be perfect or extremely detailed - drawing it shouldnt take longer than about ten minutes.
