Arctic and Alpine Soils
Proposal
(Ant)arctic (high-latitude) and alpine (mountain) areas are affected by relatively similar climates, as latitude and altitude produce similar meteorologic effects. In these geographic regions where temperature is at such a pronounced extreme, climate would seem to be the leading factor of soil development. It is my goal in this research paper to answer the following question: How do the soils of arctic and alpine areas differ? This idea, taken largely from an abstract by Birkeland (1975), will be explored through the comparison of the soils of these two geographic regions, and an analysis of the soil development factors in those environments.
Introduction
Both high-latitude and high-altitude regions are subject to climates that are dominated by extreme cold for at least part of the year. This extreme characteristic creates within these regions a stark environmental contrast to most other geographic regions of Earth, pairing with climate a different and uncommon set of geomorphologic features on the thin surficial layer of the planet. Dokuchaev (1886 & ca. 1900; and 1899, as quoted by Afanasiev (1927); and Gerasimov (1956), respectively) made progressive early studies in soil science in the Caucausus Mountains and in Arctic Russia and applied a theory that drew an analog between vertical and horizontal zonality. He observed that biota and temperature changed drastically at increasing elevations in much the way that the same characteristics vary with increasing latitude. Dokuchaev then extrapolated that the variation in biota and temperature would also indicate similar changes in soil types, but did so without sufficient observed support. While this hypothesis was a brilliant step in ea...

This is a report based on three days of observations and testing in the region known as the Peterborough drumlin field. It will address a variety of regional elements, such as climate, soil, vegetation, hydrology, geomorphology, and geology. A variety of sites located on the Canadian Shield, the zone of thick glacial deposits to the south, and the transition between them will be the focus of the report. It is supplemented with previous research on the region. September 8, 1999, day one of the field study involved an area of largely granite bedrock that is part of the Canadian Shield and is the most northern point of study (see Map 2). September 9, 1999, day two, involved three main areas of study: the Bridgenorth esker (Map 3), Mark S. Burnham Park (Map 4), and the Rice Lake drumlin (Map 6). These sites are in areas of thick glacial deposits. September 10, 1999, day three, involved studying the Warsaw Caves (see Map 5) as a transition zone between Precambrian Shield rock to the north and Paleozoic rock to the south. A general map of the entire study region is provided by Map 1.

Podzol Soils, found in the north, are used for recreation and forestry, while Luvisol Soils located in the south are for agricultural use. These leached, wet-climate soils combined with a fairly mild climate are responsible for over 50% of Canada’s class 1 agricultural land, while 62% of the land is capable of classes 1, 2, and 3.
At the end of the last ice age windblown silt covered the lava and basalt deposits. This silt would go on to create the fertile rolling hills of the Palouse. This soil is more than a hundred feet deep in places. Soon, enough time passed for vegetation to take place and more soil started to form.1 The lava flows would end up damming streams flowing from the mountains; in turn forming the current lakes of the region. Layered between the flows of basalt are sand and gravel deposits that washed down from mountains.1

Glaciers are an integral part of the world’s climate. In fact, as Richard Armstrong of the University of Colorado says, “Glaciers are key indicators in monitoring and detecting climate change” (Univ. of Colorado, Boulder, 2003, p. 1). Not only are they an important part of monitoring current climate, they can hold many keys to the past. Glaciers are in fact, “a source of paleoclimate data…” (Meier and Dyurgerov, 1980, p. 37). This paleoclimate data can give geologists information on the conditions that were present at the time of the glaciers birth, as well as the approximate age. This has an important role in the geologic time scale of the Colorado Rocky Mountains. These Glaciers played a role in the carving of the present day Rocky Mountains in Colorado, which will be the primary focus of this paper. In addition, glacial formations will be discussed to give the reader background information and the future of the Glaciers in Colorado will close this paper.
Lactase is an enzyme found in the digestive system. It is essential to the complete digestion of sugar in whole milk and milk products. Lactase specifically breaks down lactose, a complex sugar. Lactase cannot be absorbed by the body unless it is broken down by lactase into glucose and galactose. According to webMD, “Lacking lactase in their intestines, a person consuming dairy products may experience the symptoms of lactose intolerance…Abdominal cramping, flatulence (gas) and diarrhea can occur when a lactose intolerant person consumes milk products.” ("Lactase Enzyme oral : Uses, Side Effects, Interactions, Pictures, Warnings & Dosing - WebMD", n.d.) Lactase is not recommended for use in CHILDREN younger than 4 years of age. Safety and effectiveness in this age group have not been confirmed. (Kluwer, 2014)
Fitzgerald begins his comparison of new and old wealth by introducing us to the idea of chauffeurs in the beginning of the novel, when Gatsby and Nick are driving over Queensboro Bridge and pass a limousine driven by a white chauffeur and throughout the novel when people attend Gatsby’s parties. We never hear of Gatsby using his chauffeur; he walks over to Nick’s house to deliver an invitation to his party and he seeks out Jordan himself at the party. Whenever he rides in his car, he is always in the driver’s seat and his lack of chauffeur usage is shown at the end of the novel, when “the chauffeur asked him if he needed help, but he [Gatsby] shook his head and in a moment disappeared among the yellowing trees” (161). Gatsby’s lack of help from the chauffeur illustrates the control that he has over his life. He never even has the oppor...
This artic tundra is mainly formed by permafrost, “a layer of permanently frozen subsoil in the ground. Putting frozen ground and flat landscape stops the drainage of water. As the water is being held up on the surface it makes ponds and bogs that give moisture for the plants, or countering the low precipitation. “The periodic freezing and thawing of the soil forms cracks in the ground in regularly patterned polygons”. Some areas are not drained very well causing irregular landforms. Some of these landforms like the following hummocks, or knolls, frost boils, and earth stripes. Another common area to the alpine tundra is a “bare rock covered ground” also known as fell fields, in which not alone support but helps the growth of lichens. The many “microhabitats” given by these landforms provide a variety to the tundra’s landscape.

These programs need to take into perspective social and economic factors present in a young person’s life in order to incorporate positive and protective factors to prevent drug use.
Breastfeeding is a highly debated topic amongst mothers across the world. Every mother has the choice to breastfeed or bottle fed their infant. Although everyone is entitled to their own opinion and choice, it is scientifically proven that breast milk is more beneficial for the infant’s health and development and the mother. Breast milk contains extremely beneficial vitamins and nutrients and also has the ability to change according to the infant’s growth and development. Formula companies try to mock breast milk to the best they can, although it cannot be completely composed the same. “Breastfeeding offers immunological and allergy protection to the infant, is economical and convenient as it is always fresh and the right temperature, and provides a great opportunity for the mother and infant to bond” (p. 1052, Potter & Perry, 2011). Research has proven that breast milk is the most
Within the text The Great Gatsby, Fitzgerald analyzes the importance of wealth within the early twentieth century in America, which allows the reader to understand the perspectives of different social status. Moreover, he proves the importance of wealth through presenting characters that are influenced by social status. Concurrently, Fitzgerald identifies how a person’s social status shapes one’s personality and motives.

There are two major tundra biomes: the Artic Tundra and the Alpine Tundra. The Artic tundra is located around the north-pole in the northern hemisphere. This biome has temperatures of about 36 degrees Fahrenheit in the summer and about -30 degrees Fahrenheit in the winter. Bogs and ponds are common as a result of constantly frozen surface moisture and melted permafrost. As a result of these extreme conditions, tundra animals develop adaptations to survive the harsh environments. Plants in the Artic Tundra are short and grow closely to each other. Examples include mosses, heaths and lichen. They are adapted to perform photosynthesis even in the freezing conditions. The Alpine Tundra is also very cold, located on top of high mountains, often with very few trees and very little vegetative cover. They are icy for a larger part of the year. The tundra gives a clear picture of a food chain because of a small variety and population of animals and plants the snowy owl has a bird eye
