Full solutions for Investigating Astronomy: A Conceptual View of the Universe | 1st Edition
Air that has a lapse rate greater than the dry adiabatic rate.
Chemical sedimentary rock
Sedimentary rock consisting of material that was precipitated from water by either inorganic or organic means.
A principle of relative dating. A rock or fault is younger than any rock (or fault) through which it cuts.
Earth system science
An interdisciplinary study that seeks to examine Earth as a system composed of numerous interacting parts or subsystems.
Ice cap climate
A climate that has no monthly means above freezing and supports no vegetative cover except in a few scattered high mountain areas. This climate, with its perpetual ice and snow, is confined largely to the ice sheets of Greenland and Antarctica.
The solid innermost layer of Earth, about 1,300 kilometers (800 miles) in radius.
Igneous activity that occurs within a tectonic plate away from plate boundaries.
A ridge of till along the sides of an alpine glacier composed primarily of debris that fell to the glacier from the valley walls.
Deposits of windblown silt, lacking visible layers, generally buff-colored, and capable of maintaining a nearly vertical cliff.
A center of low pressure characterized by cyclonic winds.
A series of 10 minerals used as a standard in determining hardness.
The scientific study of the oceans and oceanic phenomena.
The processes that collectively result in the formation of mountains.
A curved lake produced when a stream cuts off a meander.
A lake formed during a period of increased rainfall. During the Pleistocene epoch this occurred in some nonglaciated regions during periods of ice advance elsewhere.
A wind that consistently blows from one direction more than from another.
The spontaneous decay of certain unstable atomic nuclei.
The ratio of the air’s watervapor content to its water-vapor capacity.
Unconsolidated particles created by the weathering and erosion of rock, by chemical precipitation from solution in water, or from the secretions of organisms and transported by water, wind, or glaciers.
A small lake in a cirque.
