Answer: contour lines.
Topographic maps are easily recognized by their contour lines.
The Earth's rocky outer crust solidified billions of
years ago, soon after the Earth formed. This crust is not a solid
shell; it is broken up into huge, thick plates that drift atop the soft,
underlying mantle.
The plates are made of rock and drift all over the globe; they move both
horizontally (sideways) and vertically (up and down). Over long
periods of time, the plates also change in size as their margins are
added to, crushed together, or pushed back into the Earth's mantle. These plates are from 50 to 250 miles (80 to 400 km) thick.
Erosion needs Earths rock
Erosion is wearing down and carrying away rocks by wind and moving water, happens faster with steep hillsides and heavy rain
