Sediment transport

Countdown The clock ticked down as we had less than thirty minutes to find our way out of the labyrinth that we brought upon ourselves. The further we adventured into the unknown, the more our once unscathed gleaming shoes became soiled. We kept dredging through the dense, and sticky mud that now engulfed the path. The same path that was once created with the type of gravel that crunches and crackles like pop rocks in water. Every step further lead us out of familiarity, inching into an…

Once upon a time there was an alpaca named Bluebell. She was an incredibly quintessential being with her lustrous topaz fur, doll-like ebony eyes and her uncanny ability to speak any language she encountered. She was truly remarkable. However, the most atypical thing about her wasn’t her appearance, it wasn’t her effulgent smile and it wasn’t her stubby little legs, it was the fact she was actually made entirely of plush fabric. On the morning of October 31st, Bluebell began her adventure. She…

GEOLOGIC SETTING AT OUTCROP The rocks of the Wilberns Formation have a very involved history. Today, the Wilberns outcrops are found in the Llano uplift region of central Texas, the most prolific Wilberns outcrops are to the west of the Llano uplift area (Bell and Barnes, 1972, p. 28). The Llano uplift area is a geologically complex region of central Texas (fig. 3). Precambrian metamorphic and plutonic igneous rocks mostly dominate the Llano region. The uplift brought Cambrian Wilberns rocks to…

Ian Miller is a Paleontologist who works for the Denver Museum of Nature and Science. Ian Miller’s problem is that he wants to find out how Western North America changed from the past 100 million years, what past climates were like 100 million years ago and the fossil ecosystems that existed 100 million years ago. Through solving and studying this problem, there have been many obstacles to solving his questions. Although obstacles causes trouble and hardships through experiments and test, Ian…

Around 380 million years ago, during the Devonian Period, North America and Baltica collided. This collision created another mountain range located in the same place where the Grenville Mountains and Taconic Mountains were formed. The Acadian Orogeny happened on the northeastern side of North America. Like TIA and the Grenville Belt, there was another land piece between Proto-North America and Baltica. This land piece was called Avalon. Avalon was believed to have broke apart from…

patterns. 5. Water meets friction and moves extra slow than at the surface near the middle of the stream. 6. Streams erode the landscape by scouring, lifting, abrading, and dissolving. The resulting sediment provides dissolved loads, suspended loads, and bed loads. The total quantity of sediment carried by a stream is its capacity. Capacity differs from competence, the maximum particle size a stream can carry. When stream water slows, it deposits alluvium. 7. Dissolved load- The ions of…

River otters can stay underwater for up to eight minutes and can close their ears and nostrils to keep water out! They can also dive to a depth of 60 feet!The otter is a small mammal that lives both in water and on land. There are 13 known species of otters that inhabit areas around the world Otters have a thick coat of fur which enables the otter to be warm in near freezing waters. There is also a series of thin hairs under the otters fur that help to trap air and keep the otter warm. The river…

Service). The national park lies on top of an underground evaporite layer or salt bed, which is the main cause of the formation of the arches, spires, balanced rocks, sandstone fins, and eroded monoliths in the area. ... Over 5,000 feet of younger sediments were deposited and have been mostly eroded away (Wikipedia). Water shapes this environment more than…

2.4. Hydrocarbon potential Previous work reveals presence of mature sedimentary sequence was derived from Jurassic to lower cretaceous periods in the north part of Lake Malawi which has hydrocarbon reservoir prospects. Existence of thick sedimentary sequence rock could possibly trap hydrocarbon especially in lower Shire valley, northern of Lake Malawi. Presence of large proportion volcanic clasts interbedded with sedimentary rocks transported by rivers present for extensive alluvial plain…

For each sample, provide a detailed description, as precise of a rock name as you can, and an interpretation of the (possible) environment of formation. Quaternary: This is an igneous rock known as Tuff pyroclastic, which is a volcano-clastic rick composed mainly of volcanic ash. This conclusion makes sense as the quick cooling would cause the porous structures. This rock possesses sand to mud sized grains; therefore it is fine grained. This rock has interlocking crystals as well as a…
