Solutions for Chapter 8: Weathering and Erosion
Full solutions for Focus on Physical Science: Grade 8, California | 1st Edition
The smallest particle that exists as an element.
A substance formed by the chemical combination of two or more elements in definite proportions and usually having properties different from those of its constituent elements.
An apparent group of stars originally named for mythical characters. The sky is presently divided into 88 constellations.
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.
Mass per unit volume of a substance, usually expressed as grams per cubic centimeter
Earth system science
An interdisciplinary study that seeks to examine Earth as a system composed of numerous interacting parts or subsystems.
Any break or rupture in rock along which no appreciable movement has taken place.
The gradual increase in temperature with depth in the crust. The average is 30° C per kilometer in the upper crust.
A fountain of hot water ejected periodically.
A pyramid-like peak formed by glacial action in three or more cirques surrounding a mountain summit.
The movement of surface water into rock or soil through cracks and pore spaces.
An atom or molecule that possesses an electrical charge.
Law of conservation of angular momentum
The product of the velocity of an object around a center of rotation (axis), and the distance squared of the object from the axis is constant.
The basic idea that the Sun and planets formed from the same cloud of gas and dust in interstellar space.
An unconformity in which older metamorphic or intrusive igneous rocks are overlain by younger sedimentary strata.
A molecule of oxygen containing three oxygen atoms.
A glacier that forms when one or more valley glaciers emerge from the confining walls of mountain valleys and spread out to create a broad sheet in the lowlands at the base of the mountains.
Water that flows over the land rather than infiltrating into the ground.
The release of water vapor to the atmosphere by plants.
