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.

Arête
A narrow knifelike ridge separating two adjacent glaciated valleys.

Atomic weight
The average of the atomic masses of isotopes for a given element.

Aurora
A bright display of everchanging light caused by solar radiation interacting with the upper atmosphere in the region of the poles.

Convergence
The condition that exists when the distribution of winds within a given area results in a net horizontal inflow of air into the area. Because convergence at lower levels is associated with an upward movement of air, areas of convergent winds are regions favorable to cloud formation and precipitation.

Desalination
The removal of salts and other chemicals from seawater.

Dissolved load
That portion of a stream’s load carried in solution.

Eruptive variable
A star that varies in brightness.

HertzsprungRussell diagram
See HR diagram.

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

Horizon
A layer in a soil profile.

Hydrosphere
The water portion of our planet; one of the traditional subdivisions of Earth’s physical environment.

Lightning
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.

Microcontinents
Relatively small fragments of continental crust that may lie above sea level, such as the island of Madagascar, or be submerged, as exemplified by the Campbell Plateau located near New Zealand.

Moment magnitude
A more precise measure of earthquake magnitude than the Richter scale that is derived from the amount of displacement that occurs along a fault zone.

Radiation pressure
The force exerted by electromagnetic radiation from an object such as the Sun.

Red giant
A large, cool star of high luminosity; a star occupying the upperright portion of the HertzsprungRussell diagram.

Rockforming minerals
The minerals that make up most of the rocks of Earth’s crust.

Solar constant
The rate at which solar radiation is received outside Earth’s atmosphere on a surface perpendicular to the Sun’s rays when Earth is at an average distance from the Sun.

Sunspot
A dark spot on the Sun, which is cool by contrast to the surrounding photosphere.

Supercontinent
A large landmass that contains all, or nearly all, of the existing continents.
