This textbook survival guide was created for the textbook: Introduction to the Theory of Computation, edition: 3. This expansive textbook survival guide covers the following chapters and their solutions.

Backshore
The inner portion of the shore, lying landward of the hightide shoreline. It is usually dry, being affected by waves only during storms.

Basalt
A finegrained igneous rock of mafic composition.

Convergent boundary
A boundary in which two plates move together, causing one of the slabs of lithosphere to be consumed into the mantle as it descends beneath on an overriding plate.

Craton
That part of the continental crust that has attained stability; that is, it has not been affected by significant tectonic activity during the Phanerozoic eon. It consists of the shield and stable platform.

Granitic composition
A compositional group of igneous rocks that indicates a rock is composed almost entirely of lightcolored silicates.

HR diagram
A plot of stars according to their absolute magnitudes and spectral types.

Hogback
A narrow, sharpcrested ridge formed by the upturned edge of a steeply dipping bed of resistant rock.

Lava tube
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.

Mountain breeze
The nightly downslope winds commonly encountered in mountain valleys.

Nonsilicates
Mineral groups that lack silicas in their structures and account for less than 10 percent of Earth’s crust.

Obliquity
The angle between the planes of Earth’s equator and orbit.

Perched water table
A localized zone of saturation above the main water table created by an impermeable layer (aquiclude).

Proton
A positively charged subatomic particle found in the nucleus of an atom.

Seismic waves
A rapidly moving ocean wave generated by earthquake activity capable of inflicting heavy damage in coastal regions.

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

Spiral galaxy
A flattened, rotating galaxy with pinwheellike arms of interstellar material and young stars winding out from its nucleus.

Thermocline
A layer of water in which there is a rapid change in temperature in the vertical dimension.

Transform fault
A major strikeslip fault that cuts through the lithosphere and accommodates motion between two plates.

Ultraviolet
Radiation with a wavelength from 0.2 to 0.4 micrometer.

Wave of translation
The turbulent advance of water created by breaking waves.
