An instrument used to determine wind speed.
Continental volcanic arc
Mountains formed in part by igneous activity associated with the subduction of oceanic lithosphere beneath a continent.
A mountain formed by the displacement of rock along a fault.
The group of igneous rocks composed primarily of feldspar and quartz.
A group of interrelated food chains.
A cloud that normally has its base above 6,000 meters; the base may be lower in winter and at high-latitude locations.
The concept that Earth’s crust is floating in gravitational balance upon the material of the mantle.
Mudflows on the slopes of volcanoes that result when unstable layers of ash and debris become saturated and flow downslope, usually following stream channels.
Longitudinal (seif dunes)
Long ridges of sand oriented parallel to the prevailing wind; these dunes form where sand supplies are limited.
Mean solar day
The average time between two passages of the Sun across the local celestial meridian.
A one-limbed flexure in strata. The strata are unusually flat-lying or very gently dipping on both sides of the monocline.
The nightly downslope winds commonly encountered in mountain valleys.
The angle between the planes of Earth’s equator and orbit.
The process by which most igneous rocks melt. Since individual minerals have different melting points, most igneous rocks melt over a temperature range of a few hundred degrees. If the liquid is squeezed out after some melting has occurred, a melt with a higher silica content results.
The volume of open spaces in rock or soil.
Drops of water that fall from clouds that have a diameter of at least 0.5 millimeter (0.02 inch).
A long, narrow trough bounded by normal faults. It represents a region where divergence is taking place.
The cloud of interstellar gas and/or dust from which the bodies of our solar system formed.
Sun are striking either the
Tropic of Cancer or the Tropic of Capricorn. Solstice represents the longest or shortest day (length of daylight) of the year.
A layer in the atmosphere of limited depth where the temperature increases rather than decreases with height.
