A solitary sand dune shaped like a crescent with its tips pointing downward.
A fine-grained igneous rock of mafic composition.
The yearly path of the Sun plotted against the background of stars.
A concentration of heat in the mantle capable of producing magma, which in turn extrudes onto Earth’s surface. The intraplate volcanism that produced the Hawaiian Islands is one example.
An instrument designed to measure relative humidity.
Inclination of the axis
The tilt of Earth’s axis from the perpendicular to the plane of Earth’s orbit.
A chemical bond present in all metals that may be characterized as an extreme type of electron sharing in which the electrons move freely from atom to atom.
The mass of water vapor in a unit mass of dry air; commonly expressed as grams of water vapor per kilogram of dry air.
The process by which pieces of bedrock are lifted out of place by a glacier.
Stars rich in atoms heavier than helium. Nearly always relatively young stars found in the disk of the galaxy.
The nature of the change in atmospheric pressure over the past several hours. It can be a useful aid in short range weather prediction.
The transfer of energy (heat) through space by electromagnetic waves.
The maximum quantity of water vapor that the air can hold at any given temperature and pressure.
The steep, leeward slope of a sand dune; it maintains an angle of about 34 degrees.
The downward slipping of a mass of rock or unconsolidated material moving as a unit along a curved surface.
Isolated hill of sand that exhibits a complex form and develops where wind directions are variable.
A pluton similar to but smaller than a batholith.
Wind-generated waves that have moved into an area of weaker winds or calm.
The lowermost layer of the atmosphere. It is generally characterized by a decrease in temperature with height.
