Solutions for Chapter 8: Main Memory
Full solutions for Operating System Concepts | 9th Edition
The weight of water vapor in a given volume of air (usually expressed in GRAMS/M3).
A strong attractive force that exists between atoms in a substance. It involves the transfer or sharing of electrons that allows each atom to attain a full valence shell.
The exchanges of energy and moisture that occur among the atmosphere, hydrosphere, solid Earth, biosphere, and cryosphere.
See Glacial drift.
Dry adiabatic rate
The rate of adiabatic cooling or warming in unsaturated air. The rate of temperature change is 1° C per 100 meters.
The variation of an ellipse from a circle.
The combined effect of evaporation and transpiration.
The absorption of ultraviolet light, which is reemitted as visible light.
A texture of metamorphic rocks that gives the rock a layered appearance.
Humid continental climate
A relatively severe climate characteristic of broad continents in the middle latitudes between approximately 40 and 50 degrees north latitude. This climate is not found in the Southern Hemisphere, where the middle latitudes are dominated by the oceans.
A measure of the degree of earthquake shaking at a given locale based on the amount of damage.
A ridge of till along the sides of an alpine glacier composed primarily of debris that fell to the glacier from the valley walls.
The part of the mantle that extends from the core–mantle boundary to a depth of 660 kilometers.
A ridge of till formed when lateral moraines from two coalescing alpine glaciers join.
The force exerted by electromagnetic radiation from an object such as the Sun.
The proportion of dissolved salts to pure water, usually expressed in parts per thousand (%).
A low-angle reverse fault.
A cobble or pebble polished and shaped by the sandblasting effect of wind.
