Full solutions for BSCS Biology: A Molecular Approach | 9th Edition
A subdivision of the benthic zone characterized by extremely high pressures, low temperatures, low oxygen, few nutrients, and no sunlight.
A subdivision of the mantle situated below the lithosphere. This zone of weak material exists below a depth of about 100 kilometers and in some regions extends as deep as 700 kilometers. The rock within this zone is easily deformed.
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 change of state from a gas to a liquid.
Continental (c) air mass
An air mass that forms over land; it is normally relatively dry.
The process by which water vapor is changed directly to a solid without passing through the liquid state.
A roughly circular upfolded structure similar to an anticline.
In addition to the tasks performed by conventional radar, this new generation of weather radar can detect motion directly and hence greatly improve tornado and severe storm warnings.
Large, dome-shaped structure, usually composed of granite, formed by sheeting.
A property of matter that resists a change in its motion.
Tunnel in hardened lava that acts as a horizontal conduit for lava flowing from a volcanic vent. Lava tubes allow fluid lavas to advance great distances.
Magnetic time scale
A scale that shows the ages of magnetic reversals and is based on the polarity of lava flows of various ages.
Small solid particles that have orbits in the solar system.
A one-limbed flexure in strata. The strata are unusually flat-lying or very gently dipping on both sides of the monocline.
See Jovian planet.
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.
Soil developed directly from the weathering of the bedrock below.
The rapid slide of a mass of rock downslope along planes of weakness.
A depression produced in a region where soluble rock has been removed by groundwater.
The area above the water table where openings in soil, sediment, and rock are not saturated but filled mainly with air.
