Mountains and hills
Often, mountains and hills are shown with brown or red colours or

contour lines. The darker the colour, the higher the mountain. Or,
if the contour lines are too close, it means the land is steep, like
a mountain. Hills, which are smaller than mountains, are usually

indicated with lighter brown or green colours or by close contour lines.

Valleys and plains
Valleys are the low areas between mountains or hills. On a map
they can be shown with green colours or inward-curving contour

lines. Plains, which are flat areas, are often represented with green
colours. Also, they can be represented with contour lines. If the lines
are far apart, it means that the land is flat.

Plateaus

These are flat areas on top of high land, usually shown with brown

colours. Also on a map, a plateau can be shown by contour lines
that are close on the sides and spread out on top. The spread-out

lines show the flat part of the plateau.

Generally, when using a map to identify relief of a certain area, pay
attention to the colours or contour lines. Understanding the relief of

the land is useful for various purposes, such as planning where to

build, and learning about the environment.
