Is it appropriate to intervene to help wildlife amid a disaster? That question has arisen in fire-scorched Point Reyes, where Tule elk are short of water.

Re-scooped from Professor Dixon, pretty cool story on the formation of islands in the south Pacific. A couple of them look like the island visible from the beach in Rincon, Puerto Rico where I stayed. The island is one giant rock so nobody lives there and it's a naval base for the U.S. military. This, however, is a different situation when you realize that not only do people live here, but kind of a lot of people live here.

What causes the death and the caldera in a volcano? One thing that happens in a deceased volcano is the center of the volcano starts to either erode or the inside finally caves in. Once this happen a caldera takes shape and the ocean starts to take over. As the waves eat away at the shores it will eventually create a island that is shaped like a "U". After this happens that island will someday retreat back into the ocean and someday form a barrier reef.

Based on general knowledge, I know that the taller a volcano is, the younger it is and the shorter it is, the older it is. The reason they start to get short is from erosion. Hot spots in the Earth's crust make small islands from molten rock. Young islands can be very dangerous, because if they are inhabited, they have the possibility of erupting, whereas an old island does not since the volcano is lnactice and eroding. Over time the inactive volcano will crumble and a caldera will take shape and after even more time, that caldera will slip under the ocean and become a reef. |

CULTURAL UNIT This amazing youtube video is something we watched in class, and is such a great animation. This video charts hundreds of years of cultural diffusion in a mere five minutes. You can see empires rise and crumple, people die and become born, as well as many other significant dates. This applies to the diffusion patterns of culture, because we can see where people and cultures are going throughout the centuries. |
