100
The shaking and trembling that results from movement of rock beneath Earth's surface
What is an earthquake
100
Squeezes rock until it folds or breaks, occurs at convergent boundaries
What is compression
100
Magma that has reached the surface
What is lava
100
Layer of rock that forms Earth's outer skin comprised of solid rock
What is the crust
100
Type of sedimentary rock that forms from remains of plants and animals
What is an organic rock
200
Area beneath the Earth's surface where rock is under stress, breaks triggering an earthquake
What is the focus
200
Pulls on the crust, stretching it to become thinner, occurs with divergent plates
What is tension
200
Name for the many volcanoes in the Pacific
What is the Ring of Fire
200
Center of earth made mostly of metals (iron and nickle)
What is the core
200
Type of sedimentary rock that forms when minerals that are dissolved crystallize
What is a chemical rock
300
The point on earth directly above the focus
What is an epicenter
300
Pushes a mass of rock in 2 opposite directions, occurs at a transform boundary
What is shearing
300
A property that describes the resistance of liquid flow, in magma it depends on its silica content and temperature.
What is viscosity
300
Outer layer of earth that is under oceans and lakes
What is oceanic crust
300
type of sedimentary rock that forms when rock fragments are squeezed together-range in size from microscopic to large boulders
What is a clastic rock
400
Instrument used to record seismic waves using a drum and suspended weight above with a pen attached
What is a seismograph
400
__________ fault: tension pulls rock apart. Fault is at an angle
What is divergent
400
Name given to an area where material from deep within the mantle rises, then melts forming magma
What is a hot spot
400
Layer of the mantle that is softer, hotter, and has increasing pressure
What is the lower mantle
400
Type of metamorphic rock in which grains appear in parallel layers or bands
What is a foliated rock
500
Vibrations that travel through Earth carrying energy released during an earthquake
What is a seismic wave
500
______ fault: caused by compression, rock of the crust is pushed together, blocks move in opposite directions
What is convergent
500
Weak spot in the Earth's crust where molten material, or magma, comes to the surface.
What is a volcano
500
Outer layer of earth that is the "land"
What is continental crust
500
Type of metamorphic rock in which grains are randomly arranged
What is a non foliated rock
