On a topo map, how would you determine if a feature was a hill or a valley?

c) a hill would have v shaped contour lines which are close together
d) a valley would have close together contour lines with hachures
How would a sink hole be identified on a topo map?
a) by contour lines which show higher elevation at the center of the formation
