resolution (A remote sensing term which has three separate applications: 1. spatial resolution, which refers to the ability of a sensor to distinguish between objects that are spatially close to each other. It is a measure of the smallest angular or linear separation between two objects. 2. Spectral resolution which refers to the ability of a sensor to distinguish between objects which are spectrally similar. It is a measure of both the discreteness of wavebands and the sensitivity of the sensor to distinguish between electromagnetic radiation intensity levels. 3. Thermal resolution which refers to the ability of a sensor to distinguish between objects with a similar temperature; parameter) |

persistence (The capacity of a substance to remain chemically stable. This is an important factor in estimating the environmental effects of substances discharged into the environment. Certain toxic substances (e.g., cyanides) have a low persistence, whereas other less immediately toxic substances (e.g., many organochlorines) have a high persistence and may therefore produce more serious effects) |

brushwood (Woody vegetation including shrubs and scrub trees of non-commercial height and form, often seen in the initial stages of succession following a disturbance. Brush often grows in very dense thickets that are impenetrable to wild animals and serve to suppress the growth of more desirable crop trees. However, brush can also serve an important function as desirable habitat for a range or bird, animal, and invertebrate species, and often provides a good source of browse and cover for larger wildlife. It adds structural diversity within the forest and is important in riparian zones. It is also termed scrub) |

soil settling (Compaction involves the close-packing of the individual grains mainly by the elimination of pore-space and expulsion of entrapped water; this is normally brought about by the weight of the overlying sediments) |

| دلتا |
delta (A delta is a vast, fan-shaped creation of land, or low-lying plain, formed from successive layers of sediment washed from uplands to the mouth of some rivers, such as the Nile, the Mississippi and the Ganges. The nutrient-rich sediment is deposited by rivers at the point where, or before which, the river flows into the sea. Deltas are formed when rivers supply and deposit sediments more quickly that they can be removed by waves of ocean currents. The importance of deltas was first discovered by prehistoric man, who was attracted to them because of their abundant animal and plant life. Connecting waterways through the deltas later provided natural routes for navigation and trade, and opened up access to the interior. Deltas are highly fertile and often highly populated areas. They would be under serious threat of flooding from any sea-level rise) |

DNA (The principal material of inheritance. It is found in chromosomes and consists of molecules that are long unbranched chains made up of many nucleotides. Each nucleotide is a combination of phosphoric acid, the monosaccharide deoxyribose and one of four nitrogenous bases: thymine, cytosine, adenine or guanine. The number of possible arrangements of nucleotides along the DNA chain is immense. Usually two DNA strands are linked together in parallel by specific base-pairing and are helically coiled. Replication of DNA molecules is accomplished by separation of the two strands, followed by the building up of matching strands by means of base-pairing, using the two halves as templates. By a mechanism involving RNA, the structure of DNA is translated into the structure of proteins during their synthesis from amino acids) |
