Plate Tectonics

Science

QuestionAnswer
convergent boundary where two plates come together
outer core 2,266 km thick mostly made up of metals iron and nickle consist of two parts outer and inner
plate tectonics explains theory formation movement and subduction of Earth's plate
subduction Process in which crust sinks back into the mantle through deep oceans
Pangaea Greek for all lands, German scientist said contenents drifted together
divergent boundary where two plates move apart
transform boundary where two plates slide past each other causing earthquakes
seismic waves waves cause by earthquakes
basalt dark rock found on ocean crust
granite rock found on continental crust
mantle hot solid rock over 3000 kms
lithosphere upper more part of the mantle
asthenosphere below the lithosphere
lower mantle beneath the asthenosphere and is soilid
convection current a cycle of heated molcules floating to the surface and then sinking when it cools
convection currents in earth heat from the core and mantle
conduction the way heat travels in matertials by tounching each other
radiation heat transfers through heat waves
deep ocean trench a valley along the ocean floor which crust sinks in to the mantle (subduction)
fossil ancient organism that has been preserved by rock
continental drift Wegener hypothesis that all continents were together
sonar a device that determines the distance of an object under water be recording echoes of sounds waves
rift valley a deep trech caused by divergent boundary
crust layer of rocks that forms the Earth's surface
layers of the Earth crust, mantle, lithosphere Asthenosphere, lower mantle, outer core inner core
inner core most dense part many people would think there would be hot lava there but it is actually it is solid iron and nickel
