The pink rock inside the shale is an igneous intrusion. What came first, the intrusion or the exposed rock? Which geologic law supports your answer?
This is a picture of a small intrusion. If you look closely, there are fossils around the intrusion, but there are no fossils inside the intrusion. Why?
This large rock fragment is a volcanic bomb that was thrown almost half a mile during an eruption. Because it cooled down outside of a volcano, it cooled quickly. Is it an intrusive or extrusive igneous rock? What size crystals does it have? By looking at color and crystal size, what is the name of this type of igneous rock?
This photo shows lava ripples that formed as a lava flow cooled about 60,000 years ago. Assuming you took this picture, did the lava flow to your left or right?
You are looking at a tilted rock bed. The white rock is limestone and the dark rock is a special type of shale called a mudstone. What type of weathering has caused the mudstone to weather faster than the limestone?
This is a picture of the cave entrance at Carlsbad Caverns, NM. Describe what type of weathering took place here.What type of topography has caused this cave to form?
