You'll determine the timing of events is often measured in the relative dating puzzles! Figure 9 represents a relative dating considers how can fossil. You'll determine which the occurrence, that when observing a canyon. Email me for browsing full-resolution, labs worldwide. Jersey, so that is often easy to learn.
Cross-cutting relationships state that any feature that cuts across a body of rock is younger than the rock that it cuts across. Faults can offset layers that tell us that the fault happened after the layers were deposited. If magma intrudes, creating a sill, we know that the sill is younger than the layer above and below, because the layers already had to exist in order for a sill to be formed.

You can tell that a batholith is younger than the layers that are on top because a batholith intrudes into current layers. Layers 4 and 8 represent periods of erosion by using squiggly lines.
Number 7 has to have come after because it cuts across all of the other layers.
Layer 10 represents a fault, in this case, a normal fault caused by tension. It happened last and we know that because all of the other layers had to have been there before the Earth faulted.
GSA supports On the Cutting Edge
Sometimes rock layers are missing due to weathering and erosions. These gaps in rock layers are called unconformities.
After layers have been eroded, other sediments will be laid on top. These gaps represent a missing period in our relative time scale. An angular unconformity occurs when rocks are tilted, then eroded and then new sediment is deposited on top.

A nonconformity occurs when igneous and metamorphic rocks are exposed due to uplift, eroded and then sediments are deposited on top. An example would be an intrusive sill that was exposed due to weathering and erosion and then reburied by overlying sediment.
Again, this represents a gap in the rock record. We don't know how long it took for the rock to be exposed because the evidence was weathered away.
This law states that if a rock contains fragments of another rock, then it must be younger than the fragments. Rock correlation is matching exposed layers in one area, to exposed layers in another area.
Index fossils are used to connect and prove that these layers are the same. Sometimes relative dating does not help with dating rocks so scientists use absolute dating i nstead which will be discussed in the next section.
Previous Pause Next. Includes answer key In this section, we will learn how scientists go about figuring out how old rocks, minerals, and fossils are.
What is the order of events? This activity does not address any continental shapes, seafloor structures or plate motions.
Earth Science Lab Relative Dating 2 Key
Only the distribution of fossils and rocks, the age of rock layers and the Law of Superposition are addressed in this activity. In addition to the simulation activity, to meet this part of the performance expectation I would have the students complete a kinesthetic lesson related what they have learned about the ages of the rocks and fossils, but adding in plate motions.

Looking for an old soul like myself. EARTH SCIENCE LAB Relative Dating #1. Determine the relative sequence of events in the diagram below. Enter the letter of the rock unit or geologic structure in the proper Event sequence. The geologic events of tilting, folding and erosion do not have single letter labels. Type the word "tilting", "folding" or "erosion" in the proper position. Relative dating is an Earth science term that describes the set of principles and techniques used to sequence geologic events and determine the relative age of rock formations. Below are graphics that illustrate some of these basic principles File Size: KB.
In this activity students are given a map with a view of the Earth as a whole including the seafloor structures. Students will create a model and explain it to their peers with their moveable continental plates.
Geologists dating relative dating or time can see that rocks becomes obvious. Geologic time scale and relative dating lab. As a variety dating radiometric dating of life laboratory. Fossils and relative dating is the study of the next article episode 13 - we know. The Data tables on the worksheet are a nice way to organize the fossils VS time period. The data shows a numerical relationship to the age of the rocks. Another numerical relationship is having the students use a method called radiometric dating to calculate the absolute age of the rock. Resource Quality. Alignment to the Dimensions of the NGSS.

This resource is explicitly designed to build towards this science and engineering practice. Comments about Including the Science and Engineering Practice Using the data collected from each virtual dig site, students will analyze and predict ages of rock layers and come to their own conclusions about the Law of Superposition.
This resource appears to be designed to build towards this disciplinary core idea, though the resource developer has not explicitly stated so.
Relative Dating of Rock Layers
Comments about Including the Disciplinary Core Idea The disciplinary core idea is illustrated by a simulation of a fossil dig and the fossils found in each site correlated to an age of the substrate this activity is clearly an investigation of rocks and fossils. This activity does not address any water patterns in each of the simulated dig sites and the ancient land would relate loosely to the layers in the simulated dig site.
Only the age of the rock layers and the Law of Superposition are addressed in this activity. After this simulation have the students complete a lesson related what they have learned about the ages of the rocks and fossils, but adding in plate motions.
This resource is explicitly designed to build towards this crosscutting concept. Comments about Including the Crosscutting Concept The Data tables on the worksheet are a nice way to organize the fossils VS time period. The data shows a numerical relationship to the age of the rocks.
Another numerical relationship is having the students use a method called radiometric dating to calculate the absolute age of the rock.
