The apparent brightness of a star if it were viewed from a distance of 10 parsecs (32.6 light-years). Used to compare the true brightness of stars.
A bright display of ever-changing light caused by solar radiation interacting with the upper atmosphere in the region of the poles.
See Pressure tendency.
Because the atmosphere is a complex interactive physical system, several different possible outcomes may result when one of the system’s elements is altered. These various possibilities are called climate-feedback mechanisms.
A volcano composed of both lava flows and pyroclastic material.
Moist air with a lapse rate between the dry and wet adiabatic rates.
The transfer of heat through matter by molecular activity. Energy is transferred through collisions from one molecule to another.
A cloud of interstellar dust that obscures the light of more distant stars and appears as an opaque curtain.
Environmental lapse rate
The rate of temperature decrease with increasing height in the troposphere.
An eruption in which lava is extruded from narrow fractures or cracks in the crust.
Fog formed when rain evaporates as it falls through a layer of cool air.
The resistance a mineral offers to scratching.
The 2,900-kilometer- (1,800-mile-) thick layer of Earth located below the crust.
A term often used synonymously with hypothesis but is less precise because it is sometimes used to describe a theory as well.
A subatomic particle found in the nucleus of an atom. The neutron is electrically neutral and has a mass approximately that of a proton.
A layer beneath the mantle about 2,200 kilometers (1,364 miles) thick that has the properties of a liquid.
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.
An end moraine formed as the ice front stagnated during glacial retreat.
Water that flows over the land rather than infiltrating into the ground.
Secondary (S) wave
A seismic wave that involves oscillation perpendicular to the direction of propagation.
