Smaller earthquakes that follow the main earthquake.
A theory of raindrop formation in warm clouds (above 0° C) in which large cloud droplets (giants) collide and join together with smaller droplets to form a raindrop. Opposite electrical charges may bind the cloud droplets together.
Establishing the equivalence of rocks of similar age in different areas.
An orderly arrangement of atoms.
A tabular-shaped intrusive igneous feature that cuts through the surrounding rock.
That portion of a stream’s load carried in solution.
Everything that surrounds and influences an organism.
A mountain formed by the displacement of rock along a fault.
A steep-sided inlet of the sea formed when a glacial trough was partially submerged.
A property of matter that resists a change in its motion.
A lunar rock formed when angular fragments and dust are welded together by the heat generated by the impact of a meteoroid.
The zone of beach that extends from the low-tide shoreline seaward to where waves break at low tide.
The minerals that make up most of the rocks of Earth’s crust.
The record made by a seismograph.
An eclipse of the Sun.
An elongated ridge of sand that projects from the land into the mouth of an adjacent bay.
The layer of the atmosphere immediately above the troposphere, characterized by increasing temperatures with height, owing to the concentration of ozone.
Scratches or grooves in a bedrock surface caused by the grinding action of a glacier and its load of sediment.
Periodic change in the elevation of the ocean surface.
A bench or shelf in the bedrock at sea level, cut by wave erosion.
