Place each of the igneous rocks supplied by your instructor on a numbered piece of paper. Then complete the igneous rock chart in Figure 2.12 and identify each specimen. To identify an igneous rock, follow these steps.
Step 1: Identify the texture of the rock.
Step 2: Determine the minerai composition of the rock by
a. Identifying the abundance of major minerals
or
b Estimating the mineral composition USing the color index
Step 3: Use the Igneous rock identification key In Figure 2.10 to identify the rock.

- 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.arrow_forwardPlease 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''arrow_forwardIn Sequoia National Park, why does soil moisture increase in April even though precipitation totals are on average lower in April than in March?arrow_forward
- The continents are net importers of precipitation from the oceans. We know this because, while only 15% of global evaporation occurs from the continents, the continents receive 23% of the globe’s precipitation. How is this discrepancy sustainable without the continents filling up with water and the oceans emptying out?arrow_forward6) Just 15% of global evaporation occurs over the continents even though the continents cover about 29% of the earth’s surface. Why is the proportion of global evaporation that occurs on continents less than 29%?arrow_forwardWhat are the four elements of a local water budget ? Assuming all else is held equal, what is the effect of warming on the atmosphere’s ability to evaporate water from soils and vegetation? What happens to the amount of water stored in the soil if warming affects evapotranspiration in the way you described above and there is no change to runoff?arrow_forward
- The map below shows the age of the ocean floor (time since the crust was formed). Why do we find the youngest ocean crust at the mid-ocean ridges? Why does the oldest crust tend to be near continental coasts?arrow_forwardwhat is a main piece of evidence that the continents were once all connected in a single super continent 200–300 million years ago?
