Plate Tectonics
Earthquakes
Volcanoes
Minerals
100
This is the term for a prediction based on observation and logic
Hypothesis
100
This is the name of proposed Supercontinent which existed 200 million years ago
Pangaea
100
This is the nickname for the region around the Pacific Ocean where 80% of the world's earthquakes occur
Ring of Fire
100
These are the three main types of volcanoes
Composite, Cinder Cone, Shield
100
Name three characteristics of all minerals
Solid, Inorganic, Naturally Occuring
200
This is the term for a conlcusion which has been drawn after experimentation, but lacks substantial proof
Theory
200
This is the man who established the Continental Drift Theory
Alfred Wegener
200
This is the location on the surface of the Earth above the focus of an Earthquake
Epicenter
200
These are the four types of pyroclasts listed from largest to smallest
Volcanic Bombs, Lapilli, Ash, Dust
200
This is the least reliable test when Identifying Minerals
Color
300
This is why the Earth is not a perfect sphere, but an oblate spheroid
Faster rotation at the equator
300
This Ocean is currently shrinking in size for this reason
Pacific - Subduction
300
This is the Name of the most widely accepted Theory on the cause of Earthquakes
Elastic Rebound Theory
300
This is the least explosive volcano type
Shield
300
This is the term for the ability of a Mineral to glow or change color when exposed to UV radiation
Flourescence
400
This is the grid system which allows you to locate any single point on the Earth
Latitude and Longitude Lines
400
During Seafloor Spreading, Magma rises to the surface to form this feature
Volcano
400
These are the scales which measure Magnitude and Intensity of Earthquakes and the range of values on those scales
Richter Magnitude - 1-10 Mercalli Intensity - I-XII
400
This factor determines whether mafic lava will harden as pahoehoe or aa
Rate of Cooling
400
This is the term for the ability of a mineral to break along flat, smooth surfaces
Cleavage
500
This is the name of the day when direct sunlight moves northward from the Southern hemisphere and strikes the equator?
Vernal Equinox
500
These two features are likely to form during Continental-Oceanic Convergence
Trench (Subduction Zone) and Volcanoes
500
This is the name of the process used to locate an earthquake's epicenter
Triangulation
500
This determines the viscosity (resistance to flow) of lava and whether it becomes mafic or felsic lava
Silica Content
500
This is the name of the scale measuring mineral hardness, the range of the scale, and the softest and hardest known minerals
Mohs Scale - 1-10
