For this week's blog, I decided to record the leaves rustling due to the wind as my atmospheric process. This tree is in the view from my apartment window, so it's part of an atmospheric process that I see everyday. I visited the tree on May 24th around 12PM.

From my research, I learned that the atmospheric phenomenon that I am observing is a form of wind-driven boundary layer that can impact the leaf's transpiration rate. This means that the wind has an impact on how quickly water vapor leaves the leaf through its stomata, which affects the plant's capability to take in carbon dioxide and release oxygen.


Wind-driven boundary layer forms when wind interacts with the Earth's surface and creates a layer of turbulent mixing. Some things that are necessary for this atmospheric process are strong winds, surface friction, and temperature differences. Also, I'm assuming that since we live so close to the ocean, we experience more wind compared to other places because of the sea breeze.

The tree that I recorded is probably around 6-7 feet tall, but the wind-driven boundary layer was impacting other trees that were much larger in the same area. Depending on the factors, the persistence of a wind-driven boundary layer can persist from minutes to several hours.

 Photo Blog #5 For this week's blog, I decided to visit the periodic table in the LS office. I visited the office on Friday May 1 at around 12 PM.     The mineral that is a single element that I am focused on is Gold. Gold is primarily used for jewelry, art pieces, investments and finance, electronics and industrial applications, dentistry, medicine, aerospace and defense, and many other uses. Gold is typically found in often in the form of nuggets or in quartz veins. It is usually found deep in the ground or in river and stream beds. Gold is usually extracted from the Earth through mining and then processing the extracted ore to separate the gold. The two main principal mining methods are placer and vein mining. Gold mining operations have numerous environmental consequences. Some of these include deforestation, soil erosion, water pollution, and air pollution.

 Photo Blog #6 The place I chose to visit where I believe humans have created structures to fight against erosion is the creek near the Poly Canyon Village apartments. I visited the creek at around 12:30 pm on Friday May 9th.       In this picture here, you can see the black metal piece that is placed in the water. I believe that this was man made to help slow down the flow of the creek, which would, in turn, help slow down the effects of erosion. It works by stopping the flow of the water and forcing it to slow down, similar to a speed bump. I think that erosion is still happening, but I think that the added structure definitely helps slow down erosion.
