Longest. In geologic time: - Eon Study of the origin, evolution,form, and spatial distribution of earths landforms: - Geomorphology Uppermost layer of earth: - Crust layer of earth between the crust and the core: - mantle Innermost layer of earth: - Core The crust and upper most part of the mantle refers to what sphere? - Lithosphere Beneath the lithosphere is a plastic layer known as the, - Asthenosphere A mineral must be: - Inorganic, definite chemical composition, solid. Land that rises up after layers of heavy rock or ice are removed is exhibiting is called: - Isostatic Endogenous - Farting, Folding, Volcanism, Rebound. Exogenous - Weathering, erosion, deposition The original large continental mass containing all the present continents prior to separation about 225 million years ago: - Pangea The first comprehensive theory of continental drift was put forward by, - Wegener convergent boundary - A plate boundary where two plates move toward each other. transform boundary - A plate boundary where two plates move past each other in opposite directions Boundary between crust and mantle. - Moho divergent boundary - A plate boundary where two plates move away from each other. Hawaiian islands have resulted from: - Volcanic hotspots, mantle plumes Denudation is closely related to, - Exogenic processes Mechanical weathering where water increases in volume when it freezes. - Frost wedging What type of weathering most commonly affects limestone? - Carbonation The term Karst is derived from the language and topography of what country? - Slovenia A drainage divide that separates drainage basins that empty into different bodies of water surrounding a continent are known as? - Continental divides The worlds largest rivers which has the greatest discharge: - Amazon The general term for unconsolidated clay, silt, sand, gravel, and mineral fragments deposited by running water: - Alluvium The Ultimate base level is? - Sealeval.
