Seismic waves that travel through Earth’s interior.
The bright lines produced by an incandescent gas under low pressure.
Moist air with a lapse rate between the dry and wet adiabatic rates.
Cone of depression
A cone-shaped depression in the water table immediately surrounding a well.
Spherically shaped, negatively charged zones that surround the nucleus of an atom.
A sedimentary rock formed of material deposited from solution by evaporation of water.
