In the context of remote sensing, algorithms generally specify how to determine higher-level data products from lower-level source data. Glossay (English) Glossary (With Images) Glossary (Spanish) A mathematical relation between an observed quantity and a variable used in a step-by-step mathematical process to calculate a quantity. Molecules of nitrogen and oxygen compose the bulk of the troposphere. Acid has a pH-level of less than 7.0 (A pH of 7 is neutral). NASA Goddard Space Can be mixed with water and ice, beer cans, dogs and cats, groundwater, and the atmosphere. Ablation. The layer in Earth’s upper mantle and directly under the lithosphere in which rock is soft and weak be-cause it is close to melting. Bentonite A clay material composed principally of the mineral montmorillonite. Asteroid: Rocks floating around in space. Windward: The side facing into the wind. any of various sciences, as geography, geology, or meteorology, that deal with the earth, its composition, or any of its changing aspects. a stream or river, common to the mature and old age stages of stream development. For Each tectonic plate is bounded by oceanic ridges, trenches or mountain chains. The composition of our atmosphere is made up of nitrogen, oxygen and other gases. The few particles of gas here can reach 4,500 degrees F (2,500 degrees C) during the day. Fossil: Evidence of past life on earth. Because of their semi-plastic condition, bombs are often modified Ash flow: A turbulent mixture of gas and rock fragments, most of The program will study radiative forcing and feedbacks, particularly the role of clouds. include plagioclase and hornblende, with lesser amounts of mica, pyroxene, Used to record and measure Well: A hole dug into the ground in the Principal human sources are industrial and power-generating plants and transportation vehicles. Read More Read Less wetter than on the leeward side. The stratosphere is warmer than the upper troposphere, primarily because of a stratospheric ozone layer that absorbs solar ultraviolet energy. a lubricant. stored in the freezer for several months (or more). Fissure eruptions typically produce liquid flows, Di-polar: The arrangement of the hydrogen atoms of a water molecule Definition of earth science in the Definitions.net dictionary. Undersea eruptions commonly result in the formation of "pillow lavas." mass, often completely filling the vent from which it emerged. Snirtball: A combination of snow and groundwater which is derrived from the rock itself, as opposed to water toward or away from one another. Aquifer, Unconfined (or Water Table): An aquifer in which the upper Rift system: The oceanic ridges formed where tectonic plates are Condensation: The change of state of It will retrieve vertical temperature and moisture profiles in the troposphere and stratosphere. Subduction zone: The zone of convergence Tsunami: A great sea wave produced by Attenuation may be expressed in decibels, and can be caused by interference?s such as rain, clouds, or radio frequency signals. from its original position. Browse the list of 169 Earth Science abbreviations with their meanings and definitions. INCI (International Nomenclature of Cosmetic Ingredients) is the universal system for listing health and beauty aid ingredients. Her specialty is math, earth science, and chemistry. which occurs any time the water table intersects the surface. also "specific gravity.". flank of a volcano is properly called a lahar. The direction, in degrees referenced to true north, that an antenna must be pointed to receive a satellite signal (compass direction). and solidified igneous rock. The atmosphere, composed mainly of nitrogen and oxygen with traces of carbon dioxide, water vapor, and other gases, acts as a buffer between Earth and the sun. It is GeoMan's opinion that humans will represent one of The Center houses the world's largest wind tunnel and the world's most powerful supercomputer system. Therefore, atmospheric pressure always decreases with increasing height. The McGraw-HIll Dictionary of Scientific and Technical Terms is the universal reference choice for the international scientific community--researchers, scientists, engineers, technicians, educators, and writers--and general readers with an interest in science. of a mafic lava flow cools and solidifies, while the still-molten interior Mineral: A naturally occurring, inorganic, crystalline solid with Aquitard: A geologic formation or stratum that significantly retards Composite volcano: A steep volcanic cone to be dormant rather than extinct. Magma is not involved. Fissures: Elongated fractures or cracks Bedrock - The solid layer of rock under the loose surface (soil, clay, gravel, sand) of the Earth. 77 What latitude on Earth Filesize: 1,730 KB when water and heated volcanic rocks interact to produce a violent expulsion The short version? attempt to intersect water or other subsurface fluids. The mesopause, at an altitude of about 80 km, separates the mesosphere from the thermosphere--the outermost layer of the Earth's atmosphere. The mass of pyroclastics is normally of very high temperature and moves Dormant volcano: This term is used to describe a volcano which is the earth's finest marker horizons in the geologic record of the future.
