plate tectonics vs. earthquakes Word Search

The process by which ocean floor sinks beneath a deep-ocean trench and back into the mantle subduction
When earthquakes occur they produce seismic waves
results from a force pressing on an area pressure
is the layer of rock that forms Earth's outer skin crust
a layer of hot rock mantle
The uppermost part of the mantle and the crust together form a rigid layer lithosphere
lower part of the mantle [soft layer] asthenosphere
is a layer of molten metal that surrounds the inner core outer core
is a dense ball of solid metal inner core
the transfer of energy through space radiation
heat transfer within a material or between materials that are touching conduction
can be transferred by the movement of fluids-liquids or gases convection
the flow that transfers heat within a fluid convection currents
continents slowly moving across the Earth continental drift
continually adds new material to the ocean floor sea floor spreading
the lithosphere broken up into separate sections plates
states that pieces of Earth's lithosphere are in slow, constant motion, driven by convection currents in the mantle plate tectonics
breaks in Earth's crust where rocks have slipped past each other faults
the place where two plates more apart divergent boundary
the place where two plates come together convergent boundary
a place where two plates slip past each other transform boundary

A region in which two tectonic plates are moving toward each other convergent boundary
A region in which two tectonic plates are moving apart divergent boundary
A sudden tremor or shaking of Earth's surface caused by the release of pressure as tectonic plates push against each other earthquake
A crack in Earth's crust that allows the rock on both sides to move fault
Pertaining to Earth's structure and composition geological
Molten rock above Earth's surface lava
The section of Earth that is broken into tectonic plates and consists of the crust and the rigid, uppermost part of the mantle lithosphere
Molten rock beneath Earth's surface magma
Junction where tectonic plates converge, diverge, or slide past each other and form regions of tectonic activity plate boundary
The creation of new ocean floor where tectonic plates diverge and magma is able to rise to the surface to fill the gap seafloor spreading
The process by which one tectonic plate moves under another subduction
A region in which two tectonic plates are sliding past each other transform boundary
Abrupt depressions found on the ocean floor caused by the convergence of oceanic tectonic plates trench
An opening in Earth's crust that brings magma and gases from the mantle to the surface volcano

a sudden and violent shaking of the ground, sometimes causing great destruction, as a result of movements within the earth's crust or volcanic action. Earthquake
The point on the Earth's surface that is directly above the hypocentre or focus, the point where an earthquake or underground explosion originates. Epicenter
The severity of earthquake shaking is assessed using a descriptive scale – the Modified Mercalli Intensity Scale. Intensity
An area on the margins of tectonic plates where seismic, volcanic, and tectonic activity takes place as a consequence of the relative motion of the plates. Plate Boundary
The point in the earth where the earthquake rupture or fault movement actually occurred. Focus
an instrument that measures and records details of earthquakes, such as force and duration. Seismograph
A sudden movement of the ground that releases elastic energy stored in rocks and generates seismic waves. Ground Movement
a twelve-point scale for expressing the local intensity of an earthquake, ranging from I (virtually imperceptible) to XII (total destruction). Mercalli Scale
A thin zone of crushed rock separating blocks of the earth's crust. Fault
A magnitude number to quantify the energy released by an earthquake. Richter Scale
The great size or extent of something. (size) Magnitude
A nonlinear scale used when there is a large range of quantities. Logarithmic Scale

A layer of molten metal that surrounds the inner core. outer core
The name if young German scientist who was curious about the relationship of the continents. Wegener
The name of the single continent that broke apart 200 million years ago. Pangaea
The hypothesis that the continents slowly move across earths surface continental drift
A layer of hot solid material between the crust and the core. Mantle
The layer of rock that forms earth's outer surface. crust
The soft layer of the mantle on which the Lithosphere floats. Athenosphere
The measure of how much mass there is in a volume substance. density
Heat transfer by direct contact of particles of matter. Conduction
The movement of a fluid, caused by differences in temperature, that transfers heat from one part of the fluid to each other. Convection currents
A major belt of volcanoes that rims the Pacific Ocean Ring Of Fire
A plate boundary where two plates move past each other in opposite directions. Transform Boundary
A plate boundary where two plates move away from each other. Divergent Boundary
A plate boundary where two plates move towards each other. Convergent Boundary
The transfer of energy through an empty space. Radiation
The movement of energy from a warmer object to a cooler object. Heat Transfer
A vibration that travels through earth carrying the energy released during an earthquake. Seismic Wave
A dense ball of solid metal. Inner Core
A break in Earth's crust Fault
A deep valley that forms where two plates move apart. Rift valley
The theory that pieces of Earth's lithosphere are constantly in motion, driven by convection currents in the mantle. Tectonic plates
