Stratigraphy and Cross-Dating

Two activities are included in this resource. In the first, junior geologists model sedimentary rock layers, apply the Law of Superposition, and demonstrate folding and faulting of the Earth's crust. The model is technically a sandwich....

Modeling dough and paper cutouts in science class? Learn about how relative age dating concepts, like the Law of Superposition and cross-cutting relationships, can be used to describe the formation of sedimentary layers.

Students recognize and identify gaps in historical and archaeological evidence and how that evidence is interpreted. They explore the history of the Indus cities and identify what was left behind that survived for archaeologists to find...

Young scholars identify and interpret photographic details of a Martian surface image, design, and create a simple features map. They identify and interpret the geologic history of a part of Mars' surface and then, analyze and discuss...

After a study of the principle of original horizontality and the law of superposition, and how to determine the ages of rock layers and how they are formed, students go on a field study to observe and gather information about rock...

Juvenile geologists drill clear plastic straws down into a playdough sedimentary rock model, pulling out sample rock cores. As they analyze their cores, they apply the law of superposition and discover that originally horizontal layers...

[Free Registration/Login may be required to access all resource tools.] Looks at how stratigraphy can be used to determine the relative ages of rocks, how unconformities occur, ways to match rock layers in different areas, and how...

In this rock sequence worksheet, students will sequence a list of 10 historical events according to the principle of superposition. Students will label these events on a cross-section diagram.

In this rules of the game worksheet, learners create a foldable demonstrating the laws of superposition and the principle of folding. Students will answer questions as it relates to rock layers and the principle of folding.

Think you can solve the energy problem? You'll first need to know about current energy use. Analyzing a set of circle graphs lets scholars see where energy consumption is the greatest, both by sector and by household use. They develop a...
