Full solutions for BSCS Biology: A Molecular Approach | 9th Edition
A large body of air that is characterized by a sameness of temperature and humidity.
A wide gap in the ring system of Saturn between the A ring and the B ring.
Chemical sedimentary rock
Sedimentary rock consisting of material that was precipitated from water by either inorganic or organic means.
The processes by which the internal structure of a mineral is altered by the removal and/or addition of elements.
The depression at the summit of a volcano, or that which is produced by a meteorite impact.
During the crystallization of magma, the earlier-formed minerals are denser than the liquid portion and settle to the bottom of the magma chamber.
The lifting and removal of loose material by wind.
A layer of coarse pebbles and gravel created when wind removed the finer material.
The absorption of ultraviolet light, which is reemitted as visible light.
Compensation of the lithosphere when weight is added or removed. When weight is added, the lithosphere will respond by subsiding, and when weight is removed, there will be uplift.
Metamorphic rocks that do not exhibit foliation.
The escape of gases that had been dissolved in magma.
The amount of pressure change occurring over a given distance.
A telescope that employs a lens to bend and concentrate the light from distant objects.
The ratio of the air’s watervapor content to its water-vapor capacity.
An isolated volcanic peak that rises at least 1,000 meters (3,000 feet) above the deepocean floor.
A structure composed of four oxygen atoms surrounding a silicon atom that constitutes the basic building block of silicate minerals.
Fog having the appearance of steam, produced by evaporation from a warm water surface into the cool air above.
The layer of the atmosphere immediately above the troposphere, characterized by increasing temperatures with height, owing to the concentration of ozone.
Ice crystals instead of dew that form on surfaces when the dew point is below freezing.
