Take some time now to examine some common
tools that geologists use when they are doing field work.
|
Common signs found on a geologic
map include strike and dip symbols. These symbols tell the geologist
or reader the direction a bed is trending and the angle at which the
bed is positioned compared to the horizontal (generally the Earth's
surface). Read the following definitions and go to the interactive
strike and dip site and examine
strike and dip. Best viewed in Netscapr or Safari.

2. On your
bedrock map, place strike and dip
symbols where you would expect to find them on
the flanks of your anticline and syncline. (You don't need a dip
angle)
