your answer

water always flows up hill.
true
false

on a geologic map, what does the law of superposition mean?
your answer

what does g.p.s. stand for and what is it used for?
your answer

Explanation:

1. In cartography, index contours are bold, occur every 5th contour line and have the exact elevation written on them.
2. Water flows downhill due to the force of gravity, so the statement "Water always flows up hill" is false.
3. The law of superposition in geology states that in an undisturbed sequence of sedimentary rocks, the oldest layers are at the bottom and the youngest are at the top.
4. G.P.S. stands for Global Positioning System. It is used for determining the precise location of a point on the Earth's surface, navigation, tracking, and various other applications that require location - based information.
