An exploration into the investigations used

An important secondary motive in much of the exploration so far discussed was pure scientific curiosity, the desire to add to the general store of knowledge of the world. In an important proposal for international cooperation in collecting scientific data was made by… Primary objectives and accomplishments Scientific curiosity, the desire to understand better the nature of the Earth, is a major motive for exploring its surface and subsurface regions.

Another key motive is the prospect of economic profit. Improved standards of living have increased the demand for water, fuel, and other materials, creating economic incentives.

Pure knowledge has often been a by-product of profit-motivated exploration; by the same token, substantial economic benefits have resulted from the quest for scientific knowledge. Many surface and subsurface exploratory projects are undertaken with the aim of locating: Concern for safety has prompted extensive searches for possible hazards before major construction projects are undertaken.

Sites for dams, power plants, nuclear reactors, factories, tunnels, roads, hazardous waste depositories, and so forth need to be stable and provide assurance that underlying formations will not shift or slide from the weight of the construction, move along a fault during an earthquakeor permit the seepage of water or wastes.

Accordingly, prediction and control of earthquakes and volcanic eruptions are major fields of research in the United States and Japan, countries susceptible to such hazards. Geophysical surveys furnish An exploration into the investigations used more complete picture than test boreholes alone, although some boreholes are usually drilled to verify the geophysical interpretation.

Methodology and instrumentation Geophysical techniques involve measuring reflectivity, magnetism, gravity, acoustic or elastic waves, radioactivity, heat flowelectricity, and electromagnetism. Most measurements are made on the surface of the land or sea, but some are taken from aircraft or satellites, and still others are made underground in boreholes or mines and at ocean depths.

Geophysical mapping depends on the existence of a difference in physical properties of adjacent bodies of rock—i. Often the difference is provided by something associated with but other than what is being sought.

Examples include a configuration of sedimentary layers that form a trap for oil accumulation, a drainage pattern that might affect groundwater flow, or a dike or host rock where minerals may be concentrated.

Different methods depend on different physical properties. Which particular method is used is determined by what is being sought. In most cases, however, data from a combination of methods rather than from simply one method yield a much clearer picture.

Remote sensing This comprises measurements of electromagnetic radiation from the ground, usually of reflected energy in various spectral ranges measured from aircraft or satellites. Remote sensing encompasses aerial photography and other kinds of measurements that are generally displayed in the form of photograph-like images.

Its applications involve a broad range of studies, including cartographic, botanical, geological, and military investigations. Remote-sensing techniques involve using combinations of images. Images from different flight paths can be combined to allow an interpreter to perceive features in three dimensions, while those in different spectral bands may identify specific types of rock, soil, vegetation, and other entities, where species have distinctive reflectance values in different spectral regions i.

Images taken at intervals make it possible to observe changes that occur over time, such as the seasonal growth of a crop or changes wrought by a storm or flood.

Those taken at different times of the day or at different sun angles may reveal quite distinct features; for example, seafloor features in relatively shallow water in a calm sea can be mapped when the Sun is high.

Radar radiation penetrates clouds and thus permits mapping from above them. Side-looking airborne radar SLAR is sensitive to changes in land slope and surface roughness. By registering images from adjacent flight paths, synthetic stereo pairs may give ground elevations.

Thermal infrared energy is detected by an optical-mechanical scanner. The detector is cooled by a liquid-nitrogen or liquid-helium jacket that encloses it, making the instrument sensitive at long wavelengths and isolating it from heat radiation from the immediate surroundings.

A rotating mirror directs radiation coming from various directions onto the sensor. An image can be created by displaying the output in a form synchronized with the direction of the beam as with a cathode-ray tube.

Infrared radiation permits mapping surface temperatures to a precision of less than a degree and thus shows the effects of phenomena that produce temperature variations, such as groundwater movement. Landsat images are among the most commonly used. They are produced with data obtained from a multispectral scanner carried aboard certain U.

Landsat satellites orbiting the Earth at an altitude of about kilometres. Scanner measurements are made in four spectral bands: Green, red, and infrared are recorded separately by the satellite and then combined to make the image.

Vegetation appears red, and barren land is green. The Magdalena River and nearby lakes are blue; white splotches are clouds. The roughly parallel north-south pattern along the centre right indicates rock outcrops where the rocks have been bent into a folded structure.

Changes in vegetation revealed in the images may distinguish different soil types, subtle elevation differences, subsurface water distribution, subcropping rocks, and trace element distribution, among other things.

Lineations of features may distinguish folded-rock strata or fault ruptures even where the primary features are not evident.The questionnaire sample consisted of 63 Detective Officers involved in the investigation of child abuse within the host Police Force, including Detective Constables, Sergeants and Study found that 51% of the respondents experienced a degree of STS, findings that are suggestive that STS is being experienced by a significant portion of Detective Officers who, as part of their daily duties, investigate .

Mining engineering is an engineering discipline that applies science and technology to the extraction of minerals from the earth. Mining engineering is associated with many other disciplines, such as geology, mineral processing and metallurgy, geotechnical engineering and surveying.A mining engineer may manage any phase of mining operations – from exploration and discovery of the mineral.

Featured OOH Occupation: Materials Engineers Materials engineers develop, process, and test materials used to create a wide range of products, from computer chips and aircraft wings to golf clubs and biomedical devices.

Earth exploration: Earth exploration, the investigation of the surface of the Earth and of its interior. By the beginning of the 20th century most of the Earth’s surface had been explored, at least superficially, except for the Arctic and Antarctic regions.

The authors of the latest Pearson Mathematics SL and HL books have come up with ideas for students doing their maths explorations. I have supplemented these with some more possible areas for investigation.
