While Chapters 8 and 9 consider almost purely endogenic processes, Chapter 10 takes us further out from the center of the Earth to exogenic processes. My sister and I were out for a walk when we decided to cut through the cemetery. I could not help but wonder why the tombstones below are so different. While both tombstones are roughly the same age, the top one is made out of limestone while the bottom one is made out of granite. However, the one above looks much older due to a difference in the rate of weathering. Limestone is made out of the mineral calcite, CaCO3, calcium carbonate.

Granite contains minerals such as quartz and feldspar. Both tombstones experience the same climate conditions and have been exposed to exogenic processes for the same amount of time yet they look so different! Some research into Chapter 10…

Discussion Question: Tectonics, Earthquakes and Volcanism A+ The image below can also be found in your textbook. This image is not an interpretation but an actual picture of the Red Sea. This area of the world is the East African Rift Zone separating Saudi Arabia and Africa. The linear pattern is due to extensional tectonics. In other words, Africa and Saudi Arabia are moving away from each other creating tensional forces that create normal faults. The landscape features found in the area are Rift Valleys. Pretend we are on location at the East African Rift Valley. We would find Normal Faults where one side of the fault shows a rock layer dropped relative to the other layer. We would find linear mountains that formed from the valley dropping out between the normal faults. The microscale evidence we collect helps to add up to the macroscale interpretation of a divergent boundary due to tensional forces creating normal faults and rift valleys.

Please explain why low clouds occur off of California’s coast during summer. In your explanation, please include the terms “Hadley Circulation,” “atmospheric subsidence,” and “ocean upwelling''
