Topography
Directions: Study the following vocabulary terms
Monday 3/07/11
and RULES- Memorize them for your lab Tuesday –Friday.
CONTOUR LINES- On a map, a line that connects points of equal
elevation above sea level. Every contour line eventually closes somewhere
and forms a circle or oval shape.
RULE # 1 - Contour Lines Never Cross- Lines indicating elevation
should never intersect on a topographic map, because each line represents a
different elevation, so it is impossible to have two elevations at the same
location.

CONTOUR INTERVALS- The difference in elevation between any two
contour lines on a topographic map. What are you counting by? The
contour interval on this section of the topographic map is 20, which is
probably measured in meters. The bolded lines are called the index-see
Index contour intervals below.

RULE # 2- Measuring Steepness-the closer together contour lines are,
the steeper the slope of the hill. If the spacing between lines stays the same
then the slope is constant. If the distance between lines changes, then the
slope also changes. Both --- are still only 20 meters apart in elevation, the
slope is steeper at point A because the lines are closer together. The slope
between 180 and 200 meters is more gradual-less steep.
INDEX CONTOUR INTERVALS- A contour lines that is darker than
nearby lines and has its elevation labeled. The index contour lines are
marked at 700 and 800
http://raider.mountunion.edu/~mcnaugma/Topographic%20Maps/contou7.gif
RULE # 3- Contours Close- Contour lines form irregular circles and do
not end at a random point. Every contour line can be followed around back
to where it started, although this may be beyond your map's borders.
TOPOGRAPHIC MAP- A map that shows the shape and elevation of the
land surface using contour lines, and shows other land features. (topos- is
Greek for a place)
RULE # 4- Also Known As- Contour Maps or Relief Maps. Relief is the
difference between the highest and lowest point.
The X marks the summit and gives the exact elevation of the highest pointnot consistent with the contour intervals. The summit here is 5117 and the
contour interval for this map is 100.

Under the ocean there are many
topographical features that are
similar to the topographical features
that we see on continents.
*Abyssal plains, continental shelf,
Mid-ocean ridge, Oceanic trenches,
Seamount, and Volcanic arcs*
are some oceanic features.
Directions:
Explain how a topographic map of the
seafloor would be different then one
of the continents. Would the contour
lines work the same way?
