Full solutions for Living in the Environment: Principles, Connections, and Solutions | 17th Edition
A type of volcanism that results from the eruption of magmas derived from the partial melting of ice.
An accumulation of sediment formed where a stream enters a lake or ocean.
The flat, low-lying portion of a stream valley subject to periodic inundation.
The boundary between two adjoining air masses having contrasting characteristics.
The conversion of hydrogen through fusion to form helium.
An eclipse of the Moon.
Negative feedback mechanism
A feedback mechanism that tends to maintain a system as it is—that is, maintain the status quo.
The process by which most igneous rocks melt. Since individual minerals have different melting points, most igneous rocks melt over a temperature range of a few hundred degrees. If the liquid is squeezed out after some melting has occurred, a melt with a higher silica content results.
The nature of the change in atmospheric pressure over the past several hours. It can be a useful aid in short range weather prediction.
A chain of thermonuclear reactions by which nuclei of hydrogen are built up into nuclei of helium.
A dry area on the lee side of a mountain range. Many middle-latitude deserts are of this type.
Hardened lava that has retained the vesicles produced by escaping gases.
See Cinder cone.
Rock formed from the weathered products of preexisting rocks that have been transported, deposited, and lithified.
A large, relatively flat expanse of ancient metamorphic rock within the stable continental interior.
Air that resists vertical displacement. If it is lifted, adiabatic cooling will cause its temperature to be lower than the surrounding environment; if it is allowed, it will sink to its original position.
The condition of being more highly concentrated than is normally possible under given temperature and pressure conditions. When describing humidity, it refers to a relative humidity that is greater than 100 percent.
Periodic change in the elevation of the ocean surface.
The boundary between the troposphere and the stratosphere.
Volcanic island arc
A chain of volcanic islands generally located a few hundred kilometers from a trench where active subduction of one oceanic slab beneath another is occurring.
