a concretion is a hard‚ compact mass of matter formed within layers of sedimentary rock such as sandstone‚ shale‚ siltstone‚ and limestone. Concretions form as minerals within rock beds and precipitate in cracks and cavities‚ or as sediment builds up in layers around a core like a pebble or a shell. The Finger Lakes shale holds bands of calcareous concretions that are visible in the shale layers of exposed outcroppings. The steep slopes along NY Route 21 in Woodville are an example. These smooth

DRILLING FLUIDS The key to making the rotary drilling system work is the ability to circulate a fluid continuously down through the drill pipe‚ out through the bit nozzles and back to the surface. The drilling fluid can be air‚ foam (a combination of air and liquid or a liquid. Liquid drilling fluids are commonly called drilling mud. All drilling fluids‚ especially drilling mud‚ can have a wide range of chemical and physical properties. These properties are specifically designed for

because they adapt and change when their environments change‚ and most parasites don’t harm their host so they don’t even realize they have a parasite. E. How do protozoan model multicellular organisms yet remain single cellular? Why is there an evolutionary advantage to be multicellular organism? Protozoan model multicellular organisms yet they remain single cellular because their body plan wouldn’t support them being larger so even though they have the mechanisms they don’t have the means. They also

the Midwest has a ruff terrain. High bluffs surrounding the Mississippi River and hills with narrow valleys are tucked between them. This area is said to be unglaciated. The bedrock supporting the bluffs mainly contains limestone‚ sandstone and shale. The area around the Driftless area was flattened by glacers and filled in with deposits as the glaciers melted giving the terrain a much flatter appearance and leaving the bedrock deeper beneath the surface. Since I live in such a unique and beautiful

circular transparent cells. Organisms in the fungi kingdom are mostly multicellular eukaryotes that reproduce both sexually and asexually. Fungi are also heterotrophs‚ meaning they gain energy from the consumption of other organisms. Organism three is a Daphnia which is a common water flea with a transparent body. Daphnias are apart of the Animalia kingdom‚ making it eukarya. Organisms in the kingdom Animalia are also multicellular eukaryotes that are heterotrophs and reproduce sexually. Organism four

Question Can the natural gas deposits in the Marcellus Formation‚ extracted through fracking‚ be the solution to the United States’ energy problem? Purpose The purpose of this analysis is to examine the process of extracting natural gas in shale deposits—Horizontal High Volume Slickwater Hydraulic Fracturing‚ or “Fracking”—and determine the long-term viability of this process. Information • The Marcellus Formation is a region of marine sedimentary rock that stretches through Pennsylvania

The difference between consumption and production will be made up by imports‚ which are forecasted to increase from net imports of 3.5 Tcf in 2002 (www.pstrust.org). With the increased shale gas production in the North America; natural gas imports should be discontinued. However politically‚ the nations with whom US have participated with in various bilateral agreements could be affected. For example‚

belong as their name show to the kingdom fungi. Most fungi are multicellular and consist of many complex cells. They absorb nutrients from parts of plants that are decaying in the soil for survival. These organisms are mostly parasites and also symbionts. Mushrooms‚ mold and mildew are all examples of organisms in the kingdom fungi. The kingdom of the plants is the second largest kingdom. The plants are very complex multicellular organisms. They contain chlorophyll‚ which helps them prepare their
