Geologist
A GEOLOGIST is a scientist who studies the solid and liquid matter that constitutes the Earth as well as the processes that shape it. Geologists usually study geology , although backgrounds in physics , chemistry , biology , and other sciences are also useful. Field work is an important component of geology, although many subdisciplines incorporate laboratory work. Some geologists work in the mining business searching for metals, oils, and other Earth resources. They are also in the forefront of natural hazards and disasters prevention and mitigation, studying natural hazards such as earthquakes , volcanic activity, tsunamis , weather storms. Their studies are used to warn the general public of the occurrence of these events. Geologists are also important contributors to climate change discussions

Neptunism
NEPTUNISM, a superseded scientific theory of geology proposed by Abraham Gottlob Werner
Abraham Gottlob Werner
(1749-1817) in the late 18th century, proposed rocks formed from the crystallisation of minerals in the early Earth 's oceans. The theory took its name from Neptune , the ancient Roman god of the sea. There was considerable debate between its proponents (Neptunists) and those favouring a rival theory known as plutonism which gave a significant role to volcanic origins, and which in modified form replaced neptunism in the early 19th century as the principle of uniformitarianism was shown to fit better with the geological facts as they became better known. Modern geology acknowledges many different forms of rock formation, and explains the formation of sedimentary rock through processes very similar to those described by neptunism

Plutonism
PLUTONISM (or VOLCANISM) is the geologic theory that the igneous rocks forming the Earth originated from intrusive magmatic activity , with a continuing gradual process of weathering and erosion wearing away rocks, which were then deposited on the sea bed, re-formed into layers of sedimentary rock by heat and pressure, and raised again. It proposes that basalt is solidified molten magma . The name "Plutonism" references Pluto , the classical ruler of the underworld , while "volcanism" echoes the name of Vulcan , the ancient Roman god of fire and volcanoes. The Oxford English Dictionary
Oxford English Dictionary
traces use of the word "plutonists" to 1799, and the appearance of the word "Plutonism" to 1842. Abbé Anton Moro , who had studied volcanic islands, first proposed the theory before 1750, and James Hutton
James Hutton
subsequently developed it as part of his Theory of the Earth, published in 1788

Sediment
SEDIMENT is a naturally occurring material that is broken down by processes of weathering and erosion , and is subsequently transported by the action of wind, water, or ice, and/or by the force of gravity acting on the particles. For example, sand and silt can be carried in suspension in river water and on reaching the sea be deposited by sedimentation and if buried this may eventually become sandstone and siltstone , ( sedimentary rocks ). Sediments are most often transported by water (fluvial processes ), but also wind (aeolian processes ) and glaciers . Beach sands and river channel deposits are examples of fluvial transport and deposition , though sediment also often settles out of slow-moving or standing water in lakes and oceans. Desert sand dunes and loess are examples of aeolian transport and deposition. Glacial

Sedimentology
SEDIMENTOLOGY encompasses the study of modern sediments such as sand , silt , and clay , and the processes that result in their formation (erosion and weathering ), transport , deposition and diagenesis . Sedimentologists apply their understanding of modern processes to interpret geologic history through observations of sedimentary rocks and sedimentary structures . Sedimentary rocks

Charles Darwin
CHARLES ROBERT DARWIN, FRS FRGS FLS FZS (/ˈdɑːrwɪn/ ; 12 February 1809 – 19 April 1882) was an English naturalist , geologist and biologist , best known for his contributions to the science of evolution . He established that all species of life have descended over time from common ancestors and, in a joint publication with Alfred Russel Wallace , introduced his scientific theory that this branching pattern of evolution resulted from a process that he called natural selection , in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding . Darwin published his theory of evolution with compelling evidence in his 1859 book On the Origin of Species , overcoming scientific rejection of earlier concepts of transmutation of species . By the 1870s, the scientific community and much of the general public had accepted evolution as a fact

Flow Banding
FLOW BANDING is a geological term to describe bands or layers that can sometimes be seen in rock that formed from the substance molten rock or magma. Flow banding
Flow banding
is caused by friction of the viscous magma that is in contact with a solid rock interface, usually the wall rock to an intrusive chamber or, if the magma is erupted, the surface of the earth across which the lava is flowing. The friction and viscosity of the magma causes phenocrysts and xenoliths within the magma or lava to slow down near the interface and become trapped in a viscous layer. This forms laminar flow, which manifests as a banded, streaky appearance. Flow banding
Flow banding
also results from the process of fractional crystallization that occurs by convection if the crystals that are caught in the flow-banded margins are removed from the melt. This can change the composition of the melt in large intrusions, leading to differentiation

Principles Of Geology
PRINCIPLES OF GEOLOGY: BEING AN ATTEMPT TO EXPLAIN THE FORMER CHANGES OF THE EARTH\'S SURFACE, BY REFERENCE TO CAUSES NOW IN OPERATION is a book by the Scottish geologist Charles Lyell
Charles Lyell
, first published in 3 volumes in 1830–1833. Lyell used geology throughout as a basis to strengthen his argument for Uniformitarianism
Uniformitarianism
. He used geological proof to determine that the Earth was older than 6,000 years, as had been previously contested. The book shows that the processes that are occurring in the present are the same processes that occurred in the past. The book was influential, not least on the young graduate Charles Darwin

Mathematics
MATHEMATICS (from Greek μάθημα máthēma, "knowledge, study, learning") is the study of such topics as quantity , structure , space , and change . There are many views among mathematicians and philosophers as to the exact scope and definition of mathematics . Mathematicians seek out patterns and use them to formulate new conjectures . Mathematicians resolve the truth or falsity of conjectures by mathematical proof . When mathematical structures are good models of real phenomena, then mathematical reasoning can provide insight or predictions about nature. Through the use of abstraction and logic , mathematics developed from counting , calculation , measurement , and the systematic study of the shapes and motions of physical objects. Practical mathematics has been a human activity from as far back as written records exist. The research required to solve mathematical problems can take years or even centuries of sustained inquiry
