Full solutions for A Concise Introduction to Logic | 12th Edition
Blowout (deflation hollow)
A depression excavated by the wind in easily eroded deposits.
A sedimentary rock composed of angular fragments that were lithified.
Deformation that involves the fracturing of rock. Associated with rocks near the surface.
A layer of coarse pebbles and gravel created when wind removed the finer material.
A type of unconformity in which the beds above and below are parallel.
A star that varies in brightness.
An ice-transported boulder that was not derived from bedrock near its present site.
An atom or molecule that possesses an electrical charge.
A sudden flash of light generated by the flow of electrons between oppositely charged parts of a cumulonimbus cloud or between the cloud and the ground.
Localized convective lifting
Unequal surface heating that causes localized pockets of air (thermals) to rise because of their buoyancy.
The downslope movement of rock, regolith, and soil under the direct influence of gravity.
Incandescent volcanic debris buoyed up by hot gases that moves downslope in an avalanche fashion.
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.
Drops of water that fall from clouds that have a diameter of at least 0.5 millimeter (0.02 inch).
A broad, gently sloping volcano built from fluid basaltic lavas.
Slow, downslope flow of water-saturated materials common to permafrost areas.
A climate found north of the humid continental climate and south of the polar climate and characterized by bitterly cold winters and short, cool summers. Places within this climatic realm experience the highest annual temperature ranges on Earth.
Tropical rain forest
A luxuriant broadleaf evergreen forest; also, the name given the climate associated with this vegetation.
Turbidity current deposit characterized by graded bedding.
A term applied to igneous rocks that contain small cavities called vesicles, which are formed when gases escape from lava.
