Smith went deep into debt and as creditors chased him, he was unable to enjoy any of the fruits of his labor. Forced to sell off his fossil collection, Smith eventually retreated into Northern England and lived as a pariah. Before he did, he also entered into an unwise marriage with a mentally disturbed woman. Smith was also imprisoned for his debt. Throughout much of his life, Smith received little

Unconformities In addition to creating joints and faults, the stresses of tectonic plate movement can also result in other types of strain. This can make it initially more difficult to obtain clear information from a geological record, but ultimately reveals a great deal more about geological history than more easily discernible features. Two primary concepts upon which the science of geology are founded are ideas that layers of rock initially occur

Here, the mass of water is being pulled upward toward the atmosphere by its attraction to the moon. As it does so, the tide is pulled inward from the coastlines contained the body of water. As the moon moves closer to the earth during its daily rotation, the magnetic pull lessens. The diminished pull causes the bulge to decline, pushing the body of water outward and extending the coastlines. It

Some of the grains weather to a pale green colour. In thin section, quartz is the major grain type (~50%) with some microcline (~5%) and some rock fragments (~1%) all in a fine matrix which consists of quartz and/or feldspar, mica and some calcite cement. The majority of the grains have a red-brown altered rim. The rock fragments are possibly reworked sediments" (p. 13). Lettergesh Analysis by Farrell indicates that this

Continental tropical (cT) air masses are hot, dry, unstable at low levels and generally stable aloft (upper-level ridge); they originate in northern Mexico. Continental polar (cP) or continental arctic (cA) air masses are cold, dry, and stable originating over northern Canada and Alaska as a result of radiational cooling. (Oklahoma Climatological Survey, 2004)" The greenhouse effect has been in the news for the last several decades especially with the resulting

He points out that this observation brings together the usually disparate study of deep-seated magmatic processes and land-surface evolution." (Science Daily, 2007) Marsh's study has been conducted in McMurdo's Dry Valleys which is stated to be ideal for the study of these systems "because it was eroded into its present form millions of years ago and has, unlike the rest of the Earth's surface undergone very little subsequent erosion."
