This topographic map represents the elevation of an area 100 years ago at that time the highest point had an elevation of 214 m the highest point has since eroded a total of 7 m

which profile most likely represents the landscape today

A

Explanation:

The topographic profile from West to East would generally resemble that presented in the first diagram.

The closer contour lines are together, the steeper the slope.

The farther they are apart, the more gentle it becomes.

Since the peak has been eroded by 7m,the present day peak would be 207m and would reflect in all the contour drawn.

answer; seasons change because earth tilts on its axis; and the angle of the tilt causes the northern and southern hemisphere to trade places throughout the year;

the answer would be the third option, "no, ariel should have added 9^2 and 12^2 and compared that to 15^2."

this is found through the pythagorean theorem, which is a^2 + b^2 = c^2.

this is the correct way of solving the problem:

9^2 + 12^2 = 15^2

81 + 144 = 225

225 = 225
