The Inside of the Earth
Minerals and Rocks
Plate Tectonics
Earthquakes
Volcanoes
100
The layer of the Earth which is hot, weak and plastic
What is Asthenosphere?
100
naturally occurring inorganic solids
What are Minerals
100
The theory that the continents were one supercontinent
What is Continental Drift?
100
The force that acts upon rocks in the lithosphere
What is stress?
100
The two locations where volcanoes occur
What are hot spots and plate boundaries
200
high pressure keeps this part of the Earth Solid
What is the Inner Core
200
Rocks formed from magma cooling and hardening
What is Igneous Rock?
200
cool dense lithosphere and heat from inside the Earth fuel this process
What are convection currents?
200
Longitudinal waves seismic which compress and expand
What is P waves?
200
magma accumulates in this structure beneath the surface of a volcano
What is a magma chamber?
300
The force which builds up the Earth's surface
What is Constructive
300
this is what igneous rock becomes when it is exposed to weathering and erosion
What is sediment?
300
Occurs where the oceanic plate is subducted beneath the continental plate
What is a convergent boundary?
300
changes in the rock shape or volume
What is deformation?
300
the resistance of a substance to flow
What is viscosity?
400
Flowing iron in this layer produces the electric current which creates the Earth's Magnetic Field
What is Outer Core
400
This type of rock is formed when heat and pressure are applied to sedimentary rock
What is Metamorphic?
400
What was the NEW evidence which aided in the Theory of Plate Tectonics?
What is Sea floor spreading?
400
point at which an earthquake begins beneath the surface
What is the focus?
400
The three determining factors of viscosity
What are temperature, water content, and silica content
500
This Layer is composed mostly of silicates and is a thick layer of hot solid rock
What is Mantle
500
This person is attributed as explaining the rock cycle and the idea that the same processes that happened in the past are still happening today
Who is James Hutton?
500
slip-dip and strike-slip faults occur in these areas
What is a Transform Boundary?
500
earthquake scale based on observations of intensity or ground shaking and damage
What is Modified Mercalli?
500
occurs in volcanoes which are very hot and has magma which is low in silica
What is a quiet eruption?
