Describe the spatial characteristics of drumlins in Ireland and explain their relationship to the evolution of the last lowland ice sheets in Ireland. Drumlins are undoubtedly among the most intensively studied of all glacial landforms and have bee particularly widely used as ice-directional indicators. They frequently occur in ‘fields’ or ‘swarms’ in lowland areas where there was little obstruction to the passage of ice, or in piedmont zones where flow was radiative or dispersive. They are

describes Drumlin as “prowl[ing] the house at night, yowling…looking for something she’d lost, though she didn’t know what it was” (5). For Nell, Drumlin’s inconsolable prowling is a “picture of [her] future self:[she] can’t quite remember [what she’s] lost” (5). Nell attributes the cat’s wanderings to “senility,” and adds that Drumlin forgets that she is a “carnivore,” a detail that reminds the reader of the young Nell’s desire for a life of adventure on the edge (5). However, while Drumlin forgets

A glacier forms when the climate is cold enough to prevent snow from melting in the summer months, and when it is protected and on a small decline so that the falling snow does not fall or blow away (Marshak, 2009). Periods of time when large glaciers grow and cover vast distances of continents and land is referred to as glaciation, and is often a period of time within an ice age (Marshak, 2009). Glaciers can develop in polar regions or mountainous areas where ice can survive all year (Marshak, 2009)

1) There are two types of fossils, Type I which consists of the remains of the dead animal or plant or the imprint left from the remains.This could include teeth, bones, skin impressions and hair. It could also include the hardened shell of an animal without a backbone. Type II consists of something that was made by the animal while it was living that has hardened into stone which is called trace fossils. Trace fossils include burrows, footprints, coprolite, and even animal poop. Permineralization

The Canadian Shield is the largest region in North America, meaning that it takes a massive landmass of approximately 5 million square km in range, as well as up to 50 percent of Canada’s total landmass. It is located at the Eastern side of Canada but not always on the coastline.Ranging from Nunavut’s Ellesmere Island’s Eastern Coastline to the Baffin islands and then going Southward through the middle of central Canada then to go northward up to Quebec and to the coast of Newfoundland, it resembles

Deserts, Glaciers, and Climate: Landscapes and Changes Deserts, Glaciers, and Climate: Landscapes and Changes It is no great mystery that the Earth is always changing. Talk of global warming is inescapable, making it a moral imperative to become educated about the Earth’s climate cycles and watch for changes and signs in Earth’s diverse landscapes. The following is a brief sketch of desert and glacial landscapes, as well as a look at historical and future climate

It deals with the struggles of Astronomer Dr. Ellie Arroway, who was able to make contact with an alien intelligence near the star Vega. After contact was made, her vindication of the find is short lived when people including the government, Dr. Drumlin (her supervisor), and many others rush in to take control and validate the find. However, it is discovered that the alien’s want us to build a machine that would enable a person to travel to them, which would eventually put the entire world on edge

The advance and retreat of glaciers is dependent between inputs, storage and outputs. Inputs include the accumulation of snow, avalanches, debris, heat and meltwater. Glaciers are mostly ice however, they may carry debris, moraine, and meltwater. Further, the outputs are losses are because of ablation, the melting of snow and ice and sublimation of ice to vapour and sediment. The size of a glacier is dependent on its regime (balance between rate and amount of supply of ice and the amount and rate

COLD ENVIRONMENTS All Definitions: * Quaternary Period: the latest period in geological time spanning the last 2 million years. It is sub-divided into the Pleistocene epoch (the most recent ice age) and Holocene epoch (the post-glacial period of last 10000 years). * Glacial: a period of time when masses of ice develop and advance into lower altitudes due to a sustained decline in temperature. Extensive continental ice sheets form during such periods. * Interglacial: a period of time
