Laws of Relative Rock Dating
If the letters "T" and "C" represent fossils in the oldest rock layer, they are the oldest fossils, or the first fossils formed in the past for this sequence of rock layers.
Now, look for a card that has either a "T" or "C" written on it. Since this card has a common letter with the first card, it must go on top of the "TC" card. 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. Sequence the remaining cards by using the same process.
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. Interpretation Questions: 1 After you have arranged the cards in order, write your sequence of letters using each letter only once on a separate piece of paper.
Starting with the top card, the letters should be in order from youngest to oldest.

Solve the relative dating problems in the ten blocks below. Write the answers beside the blocks, with the oldest units at the bottom and the yongest units on top. Include all events (folding, faulting, etc.) in their proper sequence. most recent on the Report Sheet. In addition to determining the relative age of the different strata, you need to determine the relative age of unconformities (erosion), cross-cuttings (faults), and in-trusion.! Leigh-Manuell - 2 Lab Activity: Relative Dating CROSS SECTION 1 CROSS SECTION 2 Limestone Sandstone Shale Conglomerate Basalt Granite.
Return to top Procedure Set B: 1 Carefully examine the second set of cards which have sketches of fossils on them. Each card represents a particular rock layer with a collection of fossils that are found in that particular rock stratum.
All of the fossils represented would be found in sedimentary rocks of marine origin.
Figure 2-A gives some background information on the individual fossils. The letters on the other cards have no significance to the sequencing procedure and should be ignored at this time. Find a rock layer that has at least one of the fossils you found in the oldest rock layer.
This rock layer would be younger as indicated by the appearance of new fossils in the rock stratum. Keep in mind that extinction is forever.Laws of Relative Rock Dating
Once an organism disappears from the sequence it cannot reappear later. In this course you will be studying the different processes, relationships, mechanisms, and concepts that help us interpret our planet Earth.

The purpose of this lab is to introduce the principles and concepts associated with both relative and absolute dating. Relative dating The relative order of geologic events can be established in most cases by applying four or fewer basic principles. (1) The Principle of Original.

WHO'S ON FIRST? RELATIVE DATING (Student Activity) INTRODUCTION Scientists have good evidence that the earth is very old, approximately four and one-half billion years old. Scientific measurements such as radiometric dating use the natural radioactivity of certain elements found in rocks to help determine their age.

Examine the geologic cross sections which follow, and determine the relative ages of the rock bodies, lettered features such as faults or surfaces of erosion, and other events such as tilting, folding, or erosion events.
Always start with the oldest rock and work toward the present. List the letters in order, with the oldest at the bottom.
For each of the relative dating diagrams, you are to think about them like they side view of a layer cake.
In general, the oldest units are on the bottom and the youngest units are on the top. There can be lots of complexities,such as folding events, faulting, erosion events,intrusion by magma, etc.
Welcome to Earth Science
You have to put these events into the order in which they occurred, starting with the oldest, and working toward the youngest. Figure out "what cuts what". If a fault cuts a bed, then the bed is older than the fault.
Then something happened. So it comes next in the sequence.
The intrusion is eroded off at the top. The previous layers are eroded off at the top too. View the Answer. There are no letters or numbers on it.
