A type of lava flow that has a jagged, blocky surface.
Smaller earthquakes that follow the main earthquake.
A solitary sand dune shaped like a crescent with its tips pointing downward.
A linear zone along which continental lithosphere stretches and pulls apart. Its creation may mark the beginning of a new ocean basin.
Geologic time scale
The division of Earth history into blocks of time—eons, eras, periods, and epochs. The time scale was created using relative dating principles.
The science that examines Earth, its form and composition, and the changes it has undergone and is undergoing.
A piece of one rock unit contained within another. Inclusions are used in relative dating. The rock mass adjacent to the one containing the inclusion must have been there first in order to provide the fragment.
The area where land and sea meet and overlap; the zone between high and low tides.
Maritime (m) air mass
An air mass that originates over the ocean. These air masses are relatively humid.
The scientific study of the atmosphere and atmospheric phenomena; the study of weather and climate.
Date that specifies the actual number of years that have passed since an event occurred.
A curved lake produced when a stream cuts off a meander.
See Energy levels.
A device consisting of two thermometers (wet bulb and dry bulb) that is rapidly whirled and, with the use of tables, yields the relative humidity and dew point.
An Earth-centered system of the universe.
A soil classification system consisting of six hierarchical categories based on observable soil characteristics. The system recognizes 12 soil orders.
The ratio of a substance’s weight to the weight of an equal volume of water.
Soils that form on unconsolidated deposits.
The boundary between the troposphere and the stratosphere.
The daily upslope winds commonly encountered in a mountain valley.
