Here is a glossary of important science experiment terms and definitions: Central Limit Theorem: States that with a large enough sample, the sample mean will be normally distributed. Key Ideas Section 1 Review Environmental Science and Earth Science Some Earth scientists study the ways in which humans interact with their environment in a relatively new field of Any of the thousands of small bodies of from 480 miles (775 km) to less than one mile (1.6 km) in diameter that revolve about the sun in orbits lying mostly between those of Mars and Jupiter. the continual movement of water among Earth's atmosphere, oceans, and land surface through evaporation, condensation, and precipitation Evaporation the process by which water molecules in liquid water escape into the air as water vapor A dynamo or similar machine for converting mechanical energy into electricity. Amazing Volcanoes. A line on a map joining points of equal height above or below sea level. A theory explaining the structure of the earth's crust and many associated phenomena as resulting from the interaction of rigid lithospheric plates that move slowly over the underlying mantle. A machine for producing continuous power in which a wheel or rotor, typically fitted with vanes, is made to revolve by a fast-moving flow of water, steam, gas, air, or other fluid. Absolute Date: An estimate of the true age of a mineral or rock based on the rate of decay of radioactive minerals. Any rock derived from magma (molten silicate material) that was poured out or ejected at Earth's surface. The ores are extracted from the earth through mining; they are then refined (often via smelting) to extract the valuable element, or elements. Key Vocabulary Terms: solar energy, transpiration, evaporation, sublimation, condensation, infiltration, precipitation, run-off, groundwater, coalescence, surface water, rain, sleet, snow, ice caps, hail, percolation, aquifer, reservoir, water vapor, and glacier. STUDY. This principle is fundamental to geologic thinking and underlies the whole development of the science of geology. Earth Science is the study of Earth and its neighbors in space. Any star lying on a diagonal band that extends from hot stars of high luminosity to cool stars of low luminosity; any stars in the Hertzsprung-Russell diagram from the upper left to the lower right of the diagram. Also called magnetic core. The explosion of a star, possibly caused by gravitational collapse, during which the star's luminosity increases by as much as 20 magnitudes and most of the star's mass is blown away at very high velocity, sometimes leaving behind an extremely dense core. Sometimes magma pushes, or intrudes, into cracks in existing rocks. long, narrow, deep parts of the seafloor formed where a subducting slab bend down into Earth. ... username: wclark407 password: w2x4e *Gain access to textbook pages, vocabulary, eActivities, and many other helpful resources as you study the various subject in your Earth Science studies!

Suggesting that Earth's geologic processes acted in the same manner and with essentially the same intensity in the past as they do in the present and that such uniformity is sufficient to account for all geologic change. Mantle - The layer of the Earth between the outer crust and the core, the mantle is made up of mostly silicate rocks. Earth's Layers Resources; 7 - Astronomy I. Astronomy Resources; 8 - Astronomy II. If the numbers associated with specific contour lines are increasing, the elevation of the terrain is also increasing. (The mantle is the hotter layer under the crust.). Relating to or produced by the internal heat of the earth. Earth science terms. A contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness of slopes. Following are definitions of common terms referring to the Theory of Evolution that everyone should know and understand, though this is by no means a comprehensive list. The space and solar system word lists are based on both the elementary and middle school science core curriculum and fit K-8 space science … Is a technique used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed. Relating to or denoting the generation of electricity using flowing water (typically from a reservoir held behind a dam or other barrier) to drive a turbine that powers a generator. the piece of iron, bundle of iron wires, or other ferrous material forming the central or inner portion in an electromagnet, induction coil, transformer, or the like. PLAY. Question: Earth’s atmosphere is composed of nearly 100 layers. Plates. Longitude. Relating to or denoting the earliest eon. Looking at what happens to the contour lines on a map when they cross a river. the region below the lithosphere, variously estimated as being from fifty to several hundred miles (eighty-five to several hundred kilometers) thick, in which the rock is less rigid than that above and below but rigid enough to transmit transverse seismic waves. The amount of water vapor present in air expressed as a percentage of the amount needed for saturation at the same temperature. Magma - Molten rock under the Earth's surface. Aa flows commonly develop from pahoehoe flows as they cool and lose gas. Formed from magma forced into older rocks at depths within the Earth's crust, which then slowly solidifies below the Earth's surface, though it may later be exposed by erosion. Geology . Match. Each new term is carefully defined and will soon become part of your Earth Science vocabulary. A storm with a violent wind, in particular a tropical cyclone in the Caribbean. A program designed to land humans on the Moon and bring them safely back to Earth. Any of a class of compounds of carbon, hydrogen, chlorine, and fluorine, typically gasses used in refrigerants and aerosol propellants.
