TEST 1 Short Answer Questions 1. Compare and contrast the formation and location of oil, coal, and natural gas reserves. Oil, coal and natural gas form from the remains of plants and animals trapped in sediment. Coal forms from large amounts of land vegetation and is trapped and enriched in place as seams. Different types of coal form according to carbon content; lignite or brown coals has the lowest carbon content; sub-‐ bituminous and bituminous coals have higher levels. Anthracite has the highest carbon content and is considered a metamorphic rock. Coal forms in swamps where continental interiors were subsiding, at the margins of shallow inland seas, and continental margins with wide continental shelves. Oil and natural gas combined is referred as petroleum and can occur together or separately. Oil forms from ocean phytoplankton trapped in shales and transformed by heat. It migrates to porous sediments and as it is less dense than the water it is found with, it becomes separated and trapped as a pool. It also forms in association with geologic traps that prevent it from leaking away such as anticlinal or up-‐folds. Natural gas is petroleum in gaseous form at normal temperatures. It often occurs with oil as associated gas. It can also occur separately from oil as non-‐associated gas and likely formed under freshwater conditions. 2. Describe, with examples the source and extraction of nuclear minerals and explain how different isotopes are used to generate power. The extraction of nuclear minerals involves the mining of the mineral Uranite (U3O8) either in open cast mines such as the Anaconda Mine in New Mexico, or underground as we see at the McArthur mine in Saskatchewan. During the transformation of radioactive isotopes (or fission) heat is produced. The heat is used to generate steam to power turbines and so generate electricity. To initiate fission, 235 uranium is bombarded with neutrons that accelerates decay and releases heat. 235U releases heat and also more neutrons that induces yet more fission. However, 235U is the least abundant of the three isotopes used. 238 U and 232 Thorium do not maintain a chain reaction like 235U. Therefore either is placed in a pile with 235U that is already undergoing fission. This converts 238U to 239 Pn (Plutonium) and 232 Th to 233 U. This takes place in a breeder reactor and the new isotopes can maintain a chain reaction. Most nuclear power plants use 235U with breeder reactors being less common as they are also considered less safe. Fill-in the blank Questions 1.
