TEKS 8.9C interpret topographic maps and satellite views to identify land and erosional
features and predict how these features may be reshaped by
weathering.
Cartographers (map makers) use data from aerial photos and remote sensing to
create maps of landforms.
Satellites orbiting the
Earth photograph
the surface to provide views of the Earth we normally would not be able to see.
These are called
topographic maps.
Topographic maps are useful because they model the three-dimensional land using lines and symbols.
Differences in elevation are
shown with the spacing between
contour lines. This is called the contour
interval.
When contour lines cross a stream or river, the lines are bent to form a “V”
shape. uphill
