Relative age dating lab activity
Presentation on theme: "RELATIVE AGE DATING LAB ACTIVITY"— Presentation transcript:
May 13, Open up your ISN. Many were large a few rare species were 5 feet in length ; crawling and swimming forms; extinct.
Tells us the sequence in which events occurred, not how long ago. The letters on the other cards have no significance to the sequencing procedure and should be ignored at this time.
Principle of original horizontality: Share buttons are a little bit lower. When you finish, you should have a vertical stack of cards with the top card representing the youngest fossils of this rock sequence and the "TC" card at the bottom of the stack representing the oldest fossils. Three-lobed body; burrowing, crawling, and swimming forms; extinct. Primitive form of chordate; floating form with branched stalks; extinct NAME: The study and comparison of exposed rock layers or strata in various parts of the earth led scientists in the early 19th century to propose that the rock layers could be correlated from place to place.
Time factors of millions and billions of years is difficult even for adults to comprehend.
WHO'S ON FIRST? RELATIVE DATING (Student Activity)
In order to do your best on this activity, you must understand a few of the basic principles that are applicable to relative age relationships between rocks: Miss Miller is older than her students.
Find a rock layer that has at least one of the fossils you found in the oldest rock layer. Since this card has a common letter with the first card, it must go on top of the "TC" card. This will enable your teacher to quickly check whether you have the correct sequence.
Comparing rock layers or fossils. Explain how you know The fault, it goes through the top layer, or The intrusion, it goes through the top layer, or The erosion at the surface of Earth which will become a future unconformity.
Primitive armored fish; extinct.
He was the first. We have learned that Earth is much older.
All of the fossils represented would be found in sedimentary rocks of marine origin. The age of a rock compared to the ages of other rocks.
Explain your reasons No, the igneous intrusion goes through all of the rock layers.
Arrange them from oldest to youngest with the oldest layer on the bottom and the youngest on top. Fossils provide important evidence of how relative age dating lab activity and environmental conditions have changed.
Figure 2-A gives some background information on the individual fossils. Three-lobed body; burrowing, crawling, and swimming forms; extinct NAME: This preview shows document pages 1 - 2.
The intrusion, it goes through the top layer, or. Both have an unconformity erosional surface at their top indicating rock material has been worn away. Squid-like animal with coiled, chambered shell; related to modern-day Nautilus. In this process, you will study the rocks and events in a geologic cross section and put them in the correct order from oldest to youngest.
