Solutions for Chapter 11.7: One Dimensional Flow in a Variable Area Duct

Plate boundaries that generate continental volcanic arcs.

See Intermediate composition.

A feldspar-rich sandstone.

A recording barometer.

A region where the rigid plates are moving apart, typified by the midoceanic ridges.

Dark, thin streaks that appear across the bright solar disk.

The division of Earth history into blocks of time—eons, eras, periods, and epochs. The time scale was created using relative dating principles.

A nearly spherically shaped group of densely packed stars.

Unequal surface heating that causes localized pockets of air (thermals) to rise because of their buoyancy.

The scientific study of the atmosphere and atmospheric phenomena; the study of weather and climate.

The escape of gases that had been dissolved in magma.

The proposed supercontinent that 200 million years ago began to break apart and form the present landmasses.

Any one of numerous minerals that have the oxygen and silicon tetrahedron as their basic structure.

A mechanism that contributes to plate motion in which cool, dense oceanic crust sinks into the mantle and “pulls” the trailing lithosphere along.

A movement common to mass-wasting processes in which the material moving downslope remains fairly coherent and moves along a well-defined surface.

Slow, downslope flow of water-saturated materials common to permafrost areas.

The study of the large-scale processes that collectively deform Earth’s crust.

A layer in the atmosphere of limited depth where the temperature increases rather than decreases with height.

A front along which a warm air mass overrides a retreating mass of cooler air.

A common term for a desert stream course that is typically dry except for brief periods immediately following a rain.
