Physical science is defined as the study of what?

Answer 1

matter & energy

Look at the topographic map of Stowe, Vermont   Figure below  . There is a steep hill rising just to the right of the city of Stowe. You can tell this because the contour lines there are closely spaced. The contour lines also show that the hill has a sharp rise of about 200 feet. Then the slope becomes less steep toward the right.
