The region in which most asteroids orbit the Sun between Mars and Jupiter.
The level below which a stream cannot erode.
The change of state from a gas to a liquid.
The quantity of water in a stream that passes a given point in a period of time.
A gaseous nebula that derives its visible light from the fluorescence of ultraviolet light from a star in or near the nebula.
A stream that is usually dry because it carries water only in response to specific episodes of rainfall. Most desert streams are of this type.
A property of matter that resists a change in its motion.
Igneous rock that formed below Earth’s surface.
Depressions created when blocks of ice became lodged in glacial deposits and subsequently melted.
The gravitational disturbance of the orbit of one celestial body by another.
See Energy levels.
An igneous rock texture resulting from the consolidation of individual rock fragments that are ejected during a violent eruption.
An end moraine formed as the ice front stagnated during glacial retreat.
Rocks are placed in their proper sequence or order. Only the chronological order of events is determined.
