answer questions based on the lab activity. throughout the reflection, make sure you have a copy of the student guide and your data tables. complete the paragraph by using the drop - down menus. in this lab, you determined the relative ages of rock layers using the principles of relative dating. the law of superposition says that a rock layer found closer to earths surface is younger than a rock layer that is deeper in earths surface. the principle of cross - cutting relationships states that intrusions are older than the rock layer they cut across. you also determined the absolute ages of rock layers using a. the data you gathered helped you identify an unknown fossil.
Answer
Brief Explanations:
The law of superposition states that in undisturbed sedimentary rock layers, the younger layers are on top of the older layers. The principle of cross - cutting relationships indicates that intrusions are younger than the rock layers they cut across. A mass spectrometer can be used to determine the absolute ages of rock layers by analyzing isotopes.
Answer:
The law of superposition says that a rock layer found closer to Earth's surface is younger than a rock layer that is deeper in Earth's surface. The principle of cross - cutting relationships states that intrusions are younger than the rock layer they cut across. You also determined the absolute ages of rock layers using a mass spectrometer.
