A star whose brightness varies periodically because it expands and contracts. A type of pulsating star.
A measure of the largest particle a stream can transport; a factor dependent on velocity.
The depression at the summit of a volcano, or that which is produced by a meteorite impact.
In addition to the tasks performed by conventional radar, this new generation of weather radar can detect motion directly and hence greatly improve tornado and severe storm warnings.
A major division on the geologic calendar; eras are divided into shorter units called periods.
The concept of an Earth-centered universe.
The conversion of hydrogen through fusion to form helium.
Mudflows on the slopes of volcanoes that result when unstable layers of ash and debris become saturated and flow downslope, usually following stream channels.
A subatomic particle found in the nucleus of an atom. The neutron is electrically neutral and has a mass approximately that of a proton.
The shape of these dunes resembles barchans, except their tips point into the wind; they often form along coasts that have strong onshore winds, abundant sand, and vegetation that partly covers the sand.
As the result of paleomagnetic studies in the 1950s, researchers proposed that either the magnetic poles migrated greatly through time or the continents had gradually shifted their positions.
The transfer of energy (heat) through space by electromagnetic waves.
A tabular igneous body that was intruded parallel to the layering of preexisting rock.
Any weathering process that tends to produce a spherical shape from an initially blocky shape.
A flow of groundwater that emerges naturally at the ground surface.
Structures that are deposited by algae and consist of layered mounds of calcium carbonate.
The region of the atmosphere immediately above the mesosphere and characterized by increasing temperatures due to absorption of very shortwave solar energy by oxygen.
The electrons involved in the bonding process; the electrons occupying the highest-principal energy level of an atom.
The dominant west-to-east motion of the atmosphere that characterizes the regions on the poleward side of the subtropical highs.
