A naturally formed, cohrerent aggregate of minerials and possibly other nonmineral matter.
What is a rock
100
A naturally formed, solid, inorganic substance with a characteristic crystal structure and a specific chemical composition.
What is a mineral
100
A vent through which magma, rock debris, volcanic ash, and gases erupt from Earth's crust to its surface.
What is a volcano
100
A model that describes the movement of water through the resevoirs of the earth system
What is the water cycle (hydrolic cycle)
100
An instrument that detects, measures, and records vibrations of Earth's surface.
What is a seismograph
200
The chemical and physical breakdown of rock exposed to air, moisture, and living organisms
What is weathering
200
An arrangement of atoms or molecules into a regular geometric lattice.
What is crystal stucture
200
A volcano composed of solidified lava flows interlayered with pyroclastic material, generally of andesitic or rhyolitic composition. These volcanos have steep sides that curve upward.
What is a stratovolcano
200
The process by which water changes from a liquid to a vapor.
What is Evaporation
200
A seismic wave that travels through Earths interior.
What is a body wave
300
The wearing away of bedrock and transport of loosened particles by a fluid such as water.
What is erosion
300
the distinctive shape of a particular mineral
What is a habit
300
Molten rock, with any suspended mineral grains and dissolved gases, that forms when melting occurs in the crust or mantle.
What is magma
300
The process by which water taken up by plants passes directly into the atmosphere.
What is transpiration
300
The first, or primary, wave to be detected by a seismograph.
What is a P wave
400
The set of crystal processes that form new rock, modify it, trnsport it, and break it down.
What is the rock cycle
400
The most common family of minerals, containing both silicate and oygen, also formed by a strong complex bond.
What is silicate minerals
400
The degree to which a substance resists flow.
What is viscosity
400
The process by which water changes from vapor into a solid.
What is deposition
400
A seismic body wave consisting of alternate pulses of compression and expansion in the direction of travel.
What is a compressional wave
500
Rocks that have been altered by exposure to high temperature, high pressure, or both.
What is a metamorphic rock
500
A localized concentration in the crust from which one or more minerals can be profitably extracted.
What is an ore deposit
500
Some examples of a secondary effect of a volcanic eruption.
What are fires and floods
500
The process by which water works its way into the ground through small openings in the soil.
What is Infiltration
500
The point on Earth's surface that is directly above an earthquake's focus.
