Dive Freshwater Caves in Florida

Brief fact about Florida freshwater Cave diving:

Florida's best is not in its saltwater but it is hidden in the northwestern corner of the state, which is riddled with freshwater springs that flow through mazes of limestone passageways. Many people ever witness the strange sights of these under water chambers fossils, sunlight beaming in from holes in the cave ceilings, and even ancient mastodon tusks because the only way to see it all is by donning a masks and flippers. As you can see the diver is deep down in the water and we can see the beauty of the water. We can see the formation of limestone and the force behind cave diving as well as the amount of water that is pouring everyday.

Eight rocks minerals of igneous

During spring break, each student was assigned to find eight rocks minerals and gave a brief description of the minerals as well as where these minerals were found. I found these eight rocks minerals on the road leading to the Intramural soccer field on Mercer University campus. I researched each rock mineral to get the correct identification of what I got from the field and from my understanding they are correct. It was a great experience to go on the field and search for minerals as student of a Geology class. The rocks minerals I collected and displayed above are: Playgiocalse feldspar, quartz, Limestone, Diorite, feldspar, andesite, Limestone, and playgioclase feldspar.   

Backyard Garden project

 

It was great to go out last week Wednesday and see how people in America make a backyard garden. We walked a few blocks from regular LAB. down College Street to view a mini-garden being made by the community. The above Raised bed has some eggplants hanging on from summer, along with some lettuce, leeks, one lone red cabbage that is struggling to make a head, broccoli, and some peas starting up the new black trellises made by the gardener. As we can see that gardener let the eggplants to go a bit too long. The eggplants turned from glossy black to egg color which is ready for harvesting. 

The next Raised bed comprises of broccoli, cauliflower, spinach, and brussels sprouts, with some beets and lacinato kale left over from a previous planting by the gardener. Fall is the season people make gardens in America because of the weather.

Slope of Land In Rio Jacarel, Brazil

This is a Slope line of the city of Rio Jacarel in Brazil and it measures both the distance and elevation. As the graph indicates the level of points on the elevation are higher because each point line is not the same. 

deep sea- Deep Sea secret

The video begins with an introduction of hydro thermal vent which states that “in many areas of high volcanic activity, water seeps into the sub-surface where it is intensely heated and then finds way to the surface again”.

It is further stated in the video that “in the ocean, this circulation occurs most commonly at the mid-ocean ridge, the world’s longest mountain chain.” It is also stated that “here, far below the depth of sunlight penetration, hydro thermal vents at over 400c with their dissolved compounds provide the basic for complex ecosystems.

The video was divided into three main categories: Mid-Atlantic Ridge, East China, and Bismarck Sea.

Mid-Atlantic Ridge

In the Mid-Atlantic Ridge, the deep sea horse mussels at a hydro-thermal vent water depth is 850m, also deep sea crab water depth is 850m. Hydro-thermal vent water depth is 860m and shrimp water depth is 855m.

East China Sea

The hydro thermal vent water depth is 1,480m and squat lobsters’ water depth is 1,500m. In this category, hydro-thermal vent water depth is also 1,500m.

Bismarck Sea

This category consists of white smoker water depth is 1,250m, shrimp at a hydro thermal vent water depth is 1,180 and squat lobsters water depth 1,220m. The black smoker water depth is 1,700-1,780m and shrimp at a black water depth is 1,720m.

The video closed with biotic community at a black smoker water depth is 1,720 and emission of liquid sulfur and bubbles water depth is 1,250m. There was lot of evaporation from the deep sea deep secret. 

Mineral Identification

 Olivine is actually a name for a series between two ends members, fayalite and forsterite. Fayalite is the iron rich member with a pure formula of Fe2SiO4. Forsterite is the magnesium rich member with a pure formula of Mg2SiO4. The two minerals form a series where the iron and magnesium are substituted for each other without much effect on the crystal structure. Fayalite due to its iron content has a higher index of infraction, is heavier and has a darker color than forsterite. Olivine has many names besides its mineral names, Fayalite and forsterite. It’s also known as ‘Chrysolite”, “evening emerald” and Peridot. This mineral interests me because of its industrial uses as well as its characteristics. This mineral has been viewed by students in class.

Graphite is a polymorph of the element carbon. Diamond is another polymorph. These two share the same Chemistry, carbon but have very different structures and very different properties.

Diamond is the hardest mineral known to man; Graphite is one of the softest.

Diamond is an excellent electrical insulator; Graphite is a good conductor of electricity.

Somewhat of a surprise is that at surface temperatures and pressures, Graphite is the stable from Carbon. This mineral interests me because of its many uses by human and its similarities with Diamond. We have talked about Graphite in class and been able to see it. It can be found in most countries and one of its uses is pencil.  In fact, all diamonds at or near the surface of the Earth are currently undergoing a transformation into Graphite.
