Relative rock dating activity


Since this card has a common letter with the first card, it must go on top of the "TC" card. The fossils within rock layer OXD i. Use this information to sequence the cards in a vertical stack of fossils in rock strata. The first card in the sequence has "Card 1, Set A" in the lower left-hand corner and represents the bottom of the sequence. Stratigraphic Section for Set B. It is not uncommon to have students reverse the M and D for example and begin the sequence with DM because that is the way they are printed on the card. This relative time scale divides the vast amount of earth history into various sections based on geological events sea encroachments, mountain-building, and depositional events , and notable biological events appearance, relative abundance, or extinction of certain life forms. By correlating fossils from various parts of the world, scientists are able to give relative ages to particular strata. All of the fossils represented would be found in sedimentary rocks of marine origin. The cards should be duplicated, laminated, and cut into sets and randomly mixed when given to the students. Once an organism disappears from the sequence it cannot reappear later. Sequence the remaining cards by using the same process. The sequence must be exactly in the order as written. By using this information from rock formations in various parts of the world and correlating the studies, scientists have been able to establish the geologic time scale. Sequencing the rock layers will show the students how paleontologists use fossils to give relative dates to rock strata. It is good at this time to remind them that these letters represent fossils in a rock layer and that one fossil next to another within a rock layer implies no particular sequencing; they both are approximately the same age as that particular rock layer. Keep in mind that extinction is forever. Starting with the top card, the letters should be in order from youngest to oldest. Explore this link for additional information on the topics covered in this lesson: For Set B , you may want to color code each organism type i. This activity illustrates this law because when the cards are placed in the correct order, the vertical stack shows the oldest fossils in a rock layer in the bottom of the stack and the youngest fossils in rock stratum on the top. Find a rock layer that has at least one of the fossils you found in the oldest rock layer. The letters on the other cards have no significance to the sequencing procedure and should be ignored at this time. Return to top To enhance this activity, have students match the fossil sketches to real fossils. If certain fossils are typically found only in a particular rock unit and are found in many places worldwide, they may be useful as index or guide fossils in determining the age of undated strata. The fossils represented by the letters on this card are "younger" than the "T" or "C" fossils on the "TC" card which represents fossils 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. Keep in mind that extinction is forever. The following question may help clarify this point. The cards in Set B represent rock layers containing various fossils. The first card in the sequence has "Card 1, Set A" in the lower left-hand corner and represents the bottom of the sequence. The fossils within rock layer OXD i. Relative dating tells scientists if a rock layer is "older" or "younger" than another. If certain fossils are typically found only in a particular rock unit and are found in many places worldwide, they may be useful as index or guide fossils in determining the age of undated strata. It may be useful to share with students after they have completed Set B and answered the Interpretation Questions. Sequence the remaining cards by using the same process. For Set B , you may want to color code each organism type i.
