With a tick or a cross mark which of the following are the correctly written and which are incorrect?

A correct measurement must not be ambiguous. A strike/dip (for a planes) must not be confused with a line (trends/plunges).
 
 

Next to the incorrect measurements write the corresponding correct measurement where possible.

******* Remember that for your next class you will need the following:

tape measure

 metric graph paper

 erasable soft pencil (No. 2) and eraser

 Brunton (supplied)

 Teacher's notes

Students can use either bearing or azimuth:

 Bearing is measured in degrees E or W from N or S

 Azimuth is measured in degrees clockwise from north

 Lines are measured with a trend/plunge and planes are measured with a strike/dip.

If numbers can go from 0-360

 Show an overhead + handout of geological symbols shown in Ch.3 of Davis.

 Explain key elements of a stratigraphic column: vertical scale, sedimentological symbols,

 horizontal scale as grain size.
