Information
Description
What It Is:
This is a geology worksheet featuring two questions about geologic cross-sections. The first question presents a block diagram of rock layers with an igneous intrusion and asks the student to identify the most recently formed rock unit. A key identifies sandstone, limestone, shale, igneous rock, and contact metamorphism. The second question shows a geologic cross-section of the Grand Canyon with numbered Paleozoic sedimentary rock layers and asks the student to identify what the unconformity between the Paleozoic and Precambrian layers represents.
Grade Level Suitability:
This worksheet is suitable for high school Earth Science or introductory college-level geology courses (Grades 9-13). The concepts of geologic cross-sections, rock types, relative dating, unconformities, and the geologic timescale are typically covered at this level.
Why Use It:
This worksheet helps students develop skills in interpreting geologic cross-sections, understanding relative dating principles, identifying rock types, and recognizing unconformities. It reinforces the concepts of geologic history and the formation of landforms like the Grand Canyon.
How to Use It:
Students should first study the provided diagrams and the key to understand the different rock types and features represented. Then, they should use their knowledge of relative dating principles and geologic processes to answer the multiple-choice questions. Encourage students to explain their reasoning for each answer.
Target Users:
This worksheet is designed for high school and introductory college students studying Earth Science, Geology, or related fields. It's also useful for teachers looking for supplemental materials to reinforce concepts related to geologic cross-sections and relative dating.
