Full solutions for Investigating Astronomy: A Conceptual View of the Universe | 1st Edition
Air with a lapse rate less than the wet adiabatic rate.
Thousands of small planetlike bodies, ranging in size from a few hundred kilometers to less than a kilometer, whose orbits lie mainly between those of Mars and Jupiter.
A poorly drained area on a floodplain that results when natural levees are present.
The quantity of water in a stream that passes a given point in a period of time.
The process of converting a liquid to a gas.
A zone of scattered clouds and calm averaging about 20 kilometers in diameter at the center of a hurricane.
The boundary between two adjoining air masses having contrasting characteristics.
An elongated, uplifted block of crust bounded by faults.
A property of matter that resists a change in its motion.
Igneous rock that formed below Earth’s surface.
The Jupiter-like planets: Jupiter, Saturn, Uranus, and Neptune. These planets have relatively low densities.
Igneous rocks with a low silica content and a high iron–magnesium content.
A wave-cut platform that has been exposed above sea level.
A span on the geologic time scale between the Paleozoic and Cenozoic eras from about 248 million to 65 million years ago.
Negative feedback mechanism
A feedback mechanism that tends to maintain a system as it is—that is, maintain the status quo.
An unconformity in which older metamorphic or intrusive igneous rocks are overlain by younger sedimentary strata.
An Earth-centered system of the universe.
An igneous rock texture resulting from the consolidation of individual rock fragments that are ejected during a violent eruption.
The area above the water table where openings in soil, sediment, and rock are not saturated but filled mainly with air.
