Four cutout block diagrams are provided at the end of this manual for additional practice and to help you visualize
structures in three dimensions. Cut and fold the diagrams as indicated, and use tape to hold the tabs together to make
three- dimensional block diagrams.
(a) Complete the blank cross-section faces for Block 1 and describe the structure present. Does the block show
horizontal or tilted strata? Folds? Faults?
(b) Complete the map view and blank cross-section faces for Blocks 2 and 3. Compare and contrast the structures in
these two blocks.
