We learned about hurricane Patricia, a category five hurricane, which set the record for hurricanes in the entire peninsula and the gulf coast. Later, Professor Johnson talked to us about deltas (a Greek word), where a river brings materials from inland and deposits this material into the sea. Some examples of deltas are: the Colorado river, the isla cerralvo, the Nile delta and the Loreto delta. We learned how sometimes deltas form hurricanes, and how rocks can represent the number of storms; usually formed by a delta.
In addition, we looked at La Niña and El Niño conditions. El Niño conditions are stronger, rougher, and windier; and in the future we will have more, evidence of global climate change. El Niño conditions form by soaking up of a lot of warm water linked to global warming. La Niña conditions are average hurricanes; the most common and normal ones.
We all walked down to the Arroyo to discover geological forces at work there. On the way there, we saw how, since there were many boulders in the road; this could mean they were brought by floods in the Arroyo. We engaged in the scientific process and created a hypothesis according to these questions 1. What are we looking at? Sand, forms of granite rocks that smash against each other. We also learned that this sand had Quartz in it. Where does this rock come from? It comes from upstream , In a flood. Ultimately sand comes from rocks crashing or peeling off. Our hypothesis was that sand forms from big boulders in flash floods, crashing to gather to create sand. We also observed the debris/brush that was stuck in between the trees. This showed us how high the flash flood had been, at about waist level. As we walked a bit further down, we saw a big boulder along with many others, that was coming from the side of the arroyo. This, we could also say, was a smaller delta. We observed how, in one part of the downhill slope of the dune, there was a driftwood line with overwash layers which indicated that the lagoon water level had risen, at least to the point we saw. And finally, we learned that whatever happens in Todos Santos also happens in Taiwan. Across the Pacific the hurricanes are stronger, and rougher. Ultimately, we saw how there were environmental patterns in places that are further along the western side of the peninsula. We saw that environmental forces are connected across the Earth, evidence of global patterns and global warming. Thank you to our science teacher, Tom Ekman for organizing amazing talks and outings with Marcus Johnson. Thank you Marcus Johnson for sharing your incredible knowledge with us.
