By looking at a map, how can you tell where the profile will be the steepest in a topographic map?

The contour lines will be closest together.

Explanation:

When contour lines are closer together, the slope is steep. When contour lines are farther apart, the slope is gentle. This is because contour lines indicate altitude. The closer the contour lines, the faster the increase in altitude, and therefore the steeper the slope.

the farther away the object is from the central star (the sun) it's gravitainal pull on the object is weaker when it is farther

explanation:

b.have there own function.
