Geological maps are important for understanding landslide and sinkhole hazards for several reasons: 1. Geological maps show the distribution and types of rock and soil materials in an area. Certain rock and soil types are more prone to landslides or developing sinkholes. 2. Geological structures like faults and folds are depicted on geological maps. Areas around geological structures may be more susceptible to slope failures or subsidence. 3. Topographic information on geological maps like slope gradients and elevation can help identify areas of existing or potential slope instability that could lead to landslides. Steep slopes are a risk factor. 4. Geological maps indicate the location of karst terrain where limestone bedrock can be dissolved by groundwater, leading to

1. Structural map-
maps that show folds,

geologic structures in
an area

10. The most
common
among these
three types of
maps are the
topographic
maps.
To read this type of map we need
to learn the rules of contour lines
these lines are connected and
they are the ones that can
determine the elevation and
formation of the place in the
map.
Elevation- Height above sea level

3. Contour lines form closed circle are
marked with straight lines indicate a

4. Contour lines that cross to the
valley or stream created aV shape
5.The spacing of contour lines
determined how steep the slope in
