Report
1. The pacific northwest of the United States is the same tectonic setting as Morrow Mountain was back when the volcanoes were active. What kind of plate boundary is this? This is a kind of "Convergent plate boundary." 2) If the foliation on rock is running north-south, what direction is the tectonic pressure coming from (be specific)? If the foliation on a rock is running north-south, the direction the tectonic pressure is coming from would be vertical. This is because foliation refers to where pressure acts and minerals show perpendicular to the direction the anxiety is going. 3) Give the rock I examined in the parking lot a name closest to the names of metamorphic rocks we learned. It's foliated with a flat surface that is just a little bit shiny from the growth of the mineral Mica. Note- I never say the name of this rock in the video. You need to look at your metamorphic rock identification grid from module 1 to give it a name. Phyllite was the metamorphic rock we examined in the parking lot that was a little shiny from the growth of Mica minerals. 4) What does it mean when a geologist says a rock is float? Should you take orientation measurements on float? When a geologist says a rock is floating, that means that the rock has been removed and transported from their original outcrops. It would be best if you took orientation measurements
on float because it helps to show the structure, but it won't be completely accurate because it might not be the whole rock due to it being transported somewhere new. 5) Why are underfit streams so common in the southern United States? Underfit streams are standard in the Southern United States because they have broad valleys, but they can't fit into the valley due to less discharge within the stream. Another way they are common in southern areas of the United States is due to their glacial melting periods 6) In Medieval times a ruler told the peasants that they were free to take anything from the forest that had fallen, branches, trees, leaves etc. But they were not to take any live standing trees. Within a few years the forest was dying. Why? The forest was dying after the Peasants took all the fallen leaves, branches, trees, etc . because, as some may say, these are gifts trees give themselves. This is because leaves are broken down to help return the vital nutrients in the soil needed to be used by other plants and themselves. 7) The area we visited was originally volcanic but the rocks we saw were metamorphic. What future geological event on the east coast of the US likely provided the heat and pressure to metamorphose the rock we saw? (hint- there is a HUGE mountain range that runs up the Eastern US and even over into the UK) The geological event that might have provided the heat and pressure to metamorphose the rock we saw in the video was the compressional activity of the rock cycle.
