Dalman - Summer questions
and answers 2025
Rule 1 of Contour Lines - answer Every point of a contour line has the same
elevation
Rule 2 of Contour Lines - answer Contour lines separate uphill from downhill
Rule 3 of Contour Lines - answer Contour lines do NOT touch or cross each other
except at a cliff
Rule 4 of Contour Lines - answer Every 5th contour line is darker in color, this is
an index contour line
Rule 5 of Contour Lines - answer Contour lines are closer together in steep terrain
and farther apart in flat areas
Rule 6 of Contour Lines - answer Contour lines close to form circles (or go off the
map) and the inside of the circle is the top of a hill
Rule 7 of Contour LInes - answer Closed depressions have hachure marks on the
downhill side of a contour line
Rule 8 of Contour Lines - answer Contour lines create V-patterns when they cross
a valley (or drainage). The tip of the V always points uphill
Rule 9 of Contour Lines - answer Contour lines creates V or U patterns when they
cross a ridge. The tp or blunt end of the V or U at a ridge always points downhill.
Rule 10 of Contour Lines - answer Contour lines on opposite sides of a valley or
ridge occur in pairs.
, Divergent Boundary - answer two tectonic plates moving away from each other
Convergent Boundary - answer two plates coming together
Transfrom Plate Boundary - answer two plates sliding past each other
How do you calculate the rate plate of motion? - answer distance divided by time
Tensional stress (extensional stress) - answer stretches rock
compressional stress - answer squeezes rock
shear stress - answer results in slippage and translation
Strain - answer a change in size, shape, or volume of a material
elastic deformation - answer the strain is reversible
ductile defromation - answer the strain is irreversible
fracture - answer irreversible strain where the material breaks
Joints - answer feature in rock that show no slippage or offset along the fracture
Dip Slip Faults - answer have an inclined fault plane where displacement or offset
has occurred in the direction of the dip
Normal Faults - answer faults that result from horizontal tensional stresses in
brittle rocks, the hanging wall block has moved down the footwall block
Reverse Faults - answer faults that result from horizontal compression stresses in
brittle rocks, the hanging wall bock has moved up the footwall block
