Lesson 2.2: A Billion-Dollar Reef
As you follow the search for petroleum and gas in this lesson, you will look back to the time when Alberta was submerged under warm, tropical sea water.
- Read pages 336 to 339 of the textbook up to the investigation. Answer the questions as you encounter them.
Check your answers with those in the “Practice Answers” in the online course.
In the next investigation you can work as a geologist to use drill-core records to determine subsurface rock formations and to possibly find oil.
- Read the investigation on pages 339 and 340 of the textbook. Follow the directions, and answer the questions.
Check your answers with those in the “Suggested Answers” in the online course.
- Read pages 340 and 341 in the textbook, starting at “Seismic Waves” and ending at the activity “Seismograph Simulation ”.
Besides using core samples to learn about subsurface rock formations, there’s another technology that can be used. In this technology, seismic shock waves are reflected off rock layers to reveal subsurface rock formations. The reflected shock waves must be detected by a seisomogram in order to be analyzed. The next activity shows how a seismograph works.
