Field geologists use a Brunton compass to

The Brunton compass is now lined up along the strike direction of the sedimentary rock units.  The red arrow is pointing along the strike direction.  What is the strike direction?

(Use the image in question 2.)  The Brunton shows that the rock unit has a strike that is indicated by the red arrow.  The rock unit is dipping in a non-vertical manner.  What are the two possible dip directions for the rock?

The top left image shows an outcrop of inclined sandstone beds in Zion National Park Utah.  The bottom left image is a close up view of the sandstone showing a Brunton compass on the sandstone.  From the extreme close up view of the Brunton compass, what is the angle of DIP of these sedimentary rock units?

What is the direction of strike of the blue (with black dots) bed in this diagram?  Notice the N (for North) on the left side of the diagram.

Using the same diagram as above, what is the direction of the dip of the yellow bed?

(Nothing strange has taken place for this diagram and the law of superposition holds true.) This is a map view, you are looking down at the horizontally bedded rocks from above. If layer A is the youngest and all of the layers of rock are horizontal, what type of structure is represented by this diagram?

(In this diagram the rock layers are not horizontal.)  What type of structure is shown by the rocks in the diagram? Notice the strike and dip symbols. This is another map view and the surface is relatively flat. (Youngest is in the center.)

Like the diagram in question 8, the beds are not horizontal  However, the oldest rock unit is now in the center.  What type of structure is shown by this diagram? 

The red "X" in the white circle is reserved for a strike and dip symbol. Which of the strike/dip symbols would geologically make sense for this spot on the map? Here is the information you need to answer this question. Mp is younger than Dck, which is younger than Dm, which is younger than Dmh, which is younger than Do. (Mp youngest is the and Do is the oldest.)

What type of structure is shown by rock units used in the above question?

What type of structure is shown on this map?  Use the strike and dip symbols.

Using the map from the previous question, which of these layers is the oldest?   Assume all of the layers are sedimentary rocks.

In this diagram the layers that are labeled GLg103 are in order from youngest to oldest. (G=Youngest and 3=Oldest) What type of structure is shown here?

This is a portion of the Grand Canyon Geologic Map produced by the United States Geologic Survey. It is a combination of a topographic map and a geologic map. Pay particular attention to the contacts of the various rock types (different colors) and the contour lines. Which strike/dip symbol correctly displays the attitude of the rocks in the mapped area? All of the symbols are in the same layer (Ph) that is written in RED to distinguish it from the other strata.

Which of these layers (as indicated by the red arrows) is the youngest?

This is a diagram of a Plunging Syncline. The diagram is part of a block diagram. The diagram is divided into 2 parts, the top represents the map view (view from above) and the bottom part of the diagram is the view from the front of the block. This is the part of the plunging syncline that would be below the surface. (If you were to print the diagram, cut it out, it would be folded along the black line at 90 degrees.) Which of the following is the correct symbol for this structure?
