Depression
Called both Elevation Lines or Contour Lines
The contours of the water table lines are the same as the contours of other topographical lines. The only indication of water tables might be elevation lines but they are not unique to water tables.
A topographical map will show contour lines and spot heights, with mountain tops marked with their height.

An easy way to draw a pie is by first drawing a circle. Next, use lines to divide the circle into slices.
A circle has infinite lines of symmetry caused by its diameter which can be rotated inside the circle.
An open circle should have a dashed circumference, a closed circle a solid one.
Topographical lines
There are infinite lines of symmetry in a circle because its diameter can revolve inside it at any position.
Draw two diameter lines, then draw a circle inside the circle.
A fraction.
The circles are called contour lines. A contour line connects points of the same elevation. When the lines are close together on a map that show the land is steep.
Four.
Called both Elevation Lines or Contour Lines
a circle with three radius lines
revelation
A circle inside a circle with three lines is a symbol commonly associated with recycling. The inner circle represents the material being recycled, while the outer circle and three arrows symbolize the process of recycling and reusing materials to reduce waste and conserve resources.
