Geologic dating activity

Cliffs and road cuts are "side views" or "geologic cross-sections" of the topography which show the relative positions of various rock layers and structures at a given spot.

Applying the principles of relative dating to these rock exposures (also called "outcrops"), we can reconstruct the sequence of events that created the geologic features which we see.

Also an igneous intrusion is present (labeled T) and a fault is present (labeled A).Question 6 (8 points): What is the sequence of events that can be inferred from the above cross-section?Below you will find our Daily Lesson Planner, Homework, and all necessary Documents.Just Scroll on down to the date you are looking for.Our focus during this unit will be on understanding the evidence the Earth presents to show us how the Earth existed in the past, and how it has changed to become the way that it exists today.

During this unit we will explore topics related to absolute and relative dating techniques; and how these teach us about the Earth's history."Athro Limited" is a private company which provides education modules on the Internet.Click Question 1 (3 points): Find the list of hypothetical geologic examples and click on "fault." We are asked to determine the correct sequence of geologic events shown by the cross-section.Question 4 (3 points): What is the sequence of events that can be inferred from the above cross-section?What principle(s) of relative dating did you use in order to arrive at your interpretation of the relative timing of each event?In the same way, such a transect could also show the inferred profile of the geology underfoot -- the expected rock layers and structures beneath the land from the northwest corner to the southeast corner of the map.
