Whats up a relative age dating activity key
D — oldest — at the bottom — superposition law.
All are near each other. Remember to include any erosion, faulting, tilting or folding!
Put the repairs in order from most recent repair to oldest work. Faunal succession deals with fossils.
Principle of original horizontality: Principle of crosscutting relations: Relative Dating of Rocks Chapter 16 in text. The easiest way to do relative age dating is to work from oldest to youngest.
E — intrusion — cross-cutting law.
Dolerite dyke is just a type of rock that has formed vertically. What has happened in each location so that they are different?
Key Terms and Laws: Look at the two nearly identical diagrams, Figures 7 and 8. A, B, D are sedimentary layers. Determining the age of materials by putting them in a sequence in order of which event took place from most recent to oldest comparative not exact.
A cross section of a cliff. The Laws of Geology: Igneous rocks are formed by the solidification of a liquid magma; the therefore can intrude into preexisting rocks or be poured out onto the surface of the earth: The opposite is true for an anticline a big dome-shaped fold.
The order of events in the archaeological cross section shows that the oldest remains are Roman. What causes anticlines and synclines?
If there are fossils embedded in the rock, these fossils inclusions are younger than the rock they are embedded in but older than the rock above them. If there were no letters, how could you tell B and B were the same age? DABEC old to young.
Principle of faunal succession: How do you know? Tilt — plate tectonics — Law of Horizontality.
A — next to bottom — superposition law. Sedimentary rocks that contain fragments of another rock are younger than the rocks that the fragments came from.
Label the diagram with anticline and syncline.
C — intrusion — Law of cross-cutting.
