A pattern of cracks that form during cooling of molten rock to generate columns that are generally six-sided.
Cone of depression
A cone-shaped depression in the water table immediately surrounding a well.
That portion of the seafloor adjacent to the continents. It may include the continental shelf, continental slope, and continental rise.
A principle of relative dating. A rock or fault is younger than any rock (or fault) through which it cuts.
A stream system that resembles the pattern of a branching tree.
The tidal current associated with the increase in the height of the tide.
Humid continental climate
A relatively severe climate characteristic of broad continents in the middle latitudes between approximately 40 and 50 degrees north latitude. This climate is not found in the Southern Hemisphere, where the middle latitudes are dominated by the oceans.
Humid subtropical climate
A climate generally located on the eastern side of a continent and characterized by hot, sultry summers and cool winters.
Organic matter in soil produced by the decomposition of plants and animals.
The conversion of hydrogen through fusion to form helium.
Ice cap climate
A climate that has no monthly means above freezing and supports no vegetative cover except in a few scattered high mountain areas. This climate, with its perpetual ice and snow, is confined largely to the ice sheets of Greenland and Antarctica.
Snow showers associated with a cP air mass to which moisture and heat are added from below as the air mass traverses a large and relatively warm lake (such as one of the Great Lakes), rendering the air mass humid and unstable.
A local wind blowing from land toward the water during the night in coastal areas.
See Lithospheric plate.
The procedure of calculating the absolute ages of rocks and minerals that contain radioactive isotopes.
Metamorphism associated with large-scale mountain-building processes.
Two belts of winds that blow almost constantly from easterly directions and are located on the equatorward sides of the subtropical highs.
Radiation with a wavelength from 0.4 to 0.7 micrometer.
A star that has exhausted most or all of its nuclear fuel and has collapsed to a very small size; believed to be near its final stage of evolution.
