The ratio of the outgoing solar radiation reflected by an object to the incoming solar radiation incident upon it. Ingredients Glossary. These sources, plus the transportation sector, are the major originators of increased nitrogen oxides. Also, what we get here in Oregon Water/bentoninte suspensions are essentially Mineral: A naturally occurring, inorganic, crystalline solid with That measurement, coupled with radial orbit knowledge, will enable determination of the topography. (p. 1 87) astronomical unit AU Earth’s average distance from the Sun, which is approximately 150 million kilometers (93 million mi). Other gases, primarily oxides of sulfur and nitrogen, are converted to strong acids (sulfuric and nitric acids). Earth Science Vocabulary 1. weather – the condition of Earth’s atmosphere at a particular time and place 2. atmosphere - the layer of gases surrounding the Earth 3. composition - the product of mixing or combining various elements or ingredients. Blizzard - A snow storm that has winds of 35 miles per hour or more. Glossary of Geoscience terms Banded ore an ore consisting of alternating layers of ore minerals and gangue material and/or host rock. deformation as opposed to fracturing and faulting. responsible for the bountiful corn and wheat fields of the American Midwest. water in the crystalline form. Principal human sources are industrial and power-generating plants and transportation vehicles. A-F G-M N-R S-Z . Commonly used to indicate a big chunk of debris which is clearly out of This region, constantly in motion, is the most dense layer of the atmosphere and the region that essentially contains all of Earth's weather. Spines: Horn-like projections formed The air surrounding the Earth, described as a series of shells or layers of different characteristics. The parallel of latitude that is approximately 66.5 degrees north of the equator and that circumscribes the northern frigid zone. a catalyst and/or lubricant. Scientists do research in these fields to discover past … Beware of building your dream house on a floodplain aquifer. undesirable. Plug: Solidified lava that fills the conduit of a volcano. Earth science or geoscience includes all fields of natural science related to the planet Earth. The layers, troposphere, stratosphere, mesosphere, thermosphere, and the exosphere, vary around the globe and in response to seasonal changes. Aquifer: A water-bearing layer of rock or sediment capable of holding Geothermal power: Power generated by Blizzard - A snow storm that has winds of 35 miles per hour or more. mass, often completely filling the vent from which it emerged. in shape during their flight or upon impact. through which volcanic materials reach the surface. Fissure eruptions typically produce liquid flows, ANY evidence of life constitutes a fossil. In the context of remote sensing, algorithms generally specify how to determine higher-level data products from lower-level source data. Each tectonic plate is bounded by oceanic ridges, trenches or mountain chains. and continental drift.
