Transcribed Image Text:How does Water Affect Carbonate Rocks? Exogenic Processes Introduction: At this lab station you will investigate how water affects carbonate rocks. To model this, you will use antacid tablets (Alka-Seltzer is one brand of antacid tablets) that contain carbonates. Materials: • Two (2) Alka-Seltzer or other brand antacid tablets • A small beaker • Water • Pair of tweezers to remove the tablet for observation • Timer or clock Procedure: 1. Take a look at the Alka-Seltzer tablet and record your careful observations. 2. Place one (1) tablet in a small beaker and cover it with water. 3. Make careful observations for three (3) minutes. Use the timer or a clock to watch the time. 4. After three (3) minutes, use the tweezers to remove the tablet and then record your observations of the surface of the tablet. Compare the tablet to an unused one to make sure your observations are accurate. 5. Write down your thoughts about how water might alter carbonate rocks. 6. Record whether you think this exploration demonstrated chemical weathering, mechanical weathering, or erosion. 7. When you're all finished, make sure you rinse out the beaker and clean up the station.
