A prediction based on observation and logic.
What is Hypothesis
100
The huge mass of land 200 million years ago, also referred as, "The Supercontinent."
What is Pangaea
100
First Waves to arrive from an earthquake
What is Primary waves
100
Regions underneath lithospheric plates which are abnormally hot and can cause volcanism in those regions.
What is Hot Spots
100
Ability of a mineral to glow or change color under UV light.
What is Fluorescence
200
The orbitation of the Earth around the Sun to complete a total of 365 days.
What is Revolution
200
The large mountain chain on the ocean floor formed due to seafloor spreading.
What is Mid-Ocean Ridge
200
The measurement of energy in seismic waves
What is magnitude
200
Small, Steep volcanoes which produce medium thick lava.
What is Cinder Cones
200
Characteristics of having regulr geometric shapes.
What is Crystal
300
Waves that are created by movement within the Earth.
What is Seismic Waves
300
The semi-liquid lower mantel where convection currents run through and move the plates above.
What is Asthenosphere
300
The point under the surface of the earth where plates fault.
What is Focus
300
Dark colored, thin lava found primarily in oceanic crusts. (non explosive)
What is Mafic Lava
300
When a mineral breaks along smooth, flat surfaces.
What is Cleavage
400
Imaginary lines wich run vertically, meaning North and South, across the Earth to distinguish locations.
What is Longitude
400
Where two plates slide past one another.
What is Transform Boundary
400
The point on the surface of the earth directly above the focus.
What is Epicenter
400
Slightly thicker than dust
What is Volcanic Ash
400
Non-living, a must for all substances to be minerals.
What is Inorganic
500
The two points on the Earth where the Earth's magnetic fields meet.
What is Geomagnetic Poles
500
The movement of heat through the asthenosphere which causes plates above to move.
What is Convection Currents
500
The straightening of plates after plates under stress snap, the cause of the majority of seismic waves.
What is Elastic Rebound Theory
500
Mafic lava which cools quickly and produces a jagged texture
