- In geology, petrifaction or petrification is the process by which organic material is converted into a fossil through the replacement of the original material and the filling of the original pore spaces with minerals. common source of silica is volcanic material. Studies have shown that in this process, most of the original organic matter is destroyed. Silicification most often occurs in two environments-either the specimen is buried in sediments of deltas and floodplains or organisms are buried in volcanic ash.

- AMPLIFICATION - The process of obtaining an output signal greater than the input signal, through auxiliary power controlled by the input signal. The process of increasing the strength, current, power, or voltage, of the signal. AMPLITUDE - The maximum instantaneous value of alternating current or voltage.

- Denitrification is the process that converts nitrate to nitrogen gas, thus removing bioavailable nitrogen and returning it to the atmosphere. Dinitrogen gas (N2) is the ultimate end product of denitrification, but other intermediate gaseous forms of nitrogen exist (Figure 7).

How to Plant a Cactus Container Garden Beginning with the largest cactus, ease each plant gently out of its old container. Wear gloves and use tongs or wrap the cactus in newspaper, paper towels, or light cardboard. Press the newly planted cactus down using the back of a spoon. Transplant the rest of the dish with the remaining cactus plants.

Biomagnification Biomagnification, also known as bioamplification or biological magnification, occurs when the concentration of a substance, such as DDT or mercury, in an organism exceeds the background concentration of the substance in its diet. This increase can occur as a result of:

Magnification Magnification is the process of enlarging something only in appearance, not in physical size. This enlargement is quantified by a calculated number also called magnification. When this number is less than one, it refers to a reduction in size, sometimes called minification or de-magnification.

Pasteurization Pasteurization (or pasteurisation) is a process of making foods stay fresh. It involves heating the food to kill most harmful microorganisms. Producers pasteurize dairy and other foods to make them safe to eat. The process is named after Louis Pasteur.

Nitrogen cycle Denitrification is the reduction of nitrates back into the largely inert nitrogen gas (N 2), completing the nitrogen cycle. This process is performed by bacterial species such as Pseudomonas and Clostridium in anaerobic conditions.mportant processes in the nitrogen cycle include fixation, ammonification, nitrification, and denitrification. The majority of Earth's atmosphere (78%) is nitrogen, making it the largest pool of nitrogen.

We couldn't find any results for your search. Petrified wood. Petrified wood is the name given to a special type of fossilized remains of terrestrial vegetation. It is the result of a tree or tree-like plants having completely transitioned to stone by the process of permineralization.ll the organic materials have been replaced with minerals, while retaining the original structure of the stem tissue. Unlike other types of fossils which are typically impressions or compressions, petrified wood is a three-dimensional representation of the original organic material.

Mummification Mummification is a process in which the skin and flesh of a corpse can be preserved. The process can occur either naturally, or it can be intentional. If it occurs naturally, it is the result of cold (as can be found in a glacier), acid (as can be found in a bog) or dryness.

Lustration Lustration in general is the process of making something clear or pure, usually by means of a propitiatory offering. The term is taken from the Roman lustratio purification rituals.

clarification Clarification. The removal of small amounts of fine, particulate solids from liquids. The purpose is almost invariably to improve the quality of the liquid, and the removed solids often are discarded.The particles removed by a clarifier may be as large as 100 micrometers or as small as 2 micrometers.larification. (chemical engineering). The removal of small amounts (usually less than 0.2%) of fine particulate solids from liquids (such as drinking water) by methods such as gravity sedimentation, centrifugal sedimentation, filtration, and magnetic separation.

Fossilization Permineralization burial before decay is advanced. The degree to which the remains are decayed when buried determines the later details of the fossil. Carbonization (Distillation) Carbonization is a process by which the more volatile substances of plants and animals decay, but leave behind the carbon.

The process of permineralization Petrification (petros means stone) occurs when the organic matter is completely replaced by minerals and the fossil is turned to stone. This generally occurs by filling the pores of the tissue, and inter and intra cellular spaces with minerals, then dissolving the organic matter and replacing it with minerals. This method reproduces the original tissue in every detail. This kind of fossilization occurs in both hard and soft tissues. An example of this kind of fossilization is petrified wood. The process of permineralization. The ground water generally do not contain pure water molecules alone. It is hard to some

- Pasteurization is a process of heating a food (usually a liquid), to a minimum of 145 degrees F (up to over 200 degrees F) for a definite length of time, and then cooling it immediately, to slow the microbial growth.asteurization of foods does only one thing, really… and that’s to increase the foods shelf life. INCREASING SHELF LIFE.. INCREASES PROFITS OF FOOD PRODUCERS. All Pasteurization is BAD because it kills ALL the Living Enzymes in the FOOD and severely diminishes the nutritive value of the food.

Petrified wood Petrified wood is a fossil in which the organic remains have been replaced by minerals in the slow process of being replaced with stone. This petrification process generally results in a quartz chalcedony mineralization.etrified wood is a fossil in which the organic remains have been replaced by minerals in the slow process of being replaced with stone.
