plate tectonics

The theory that the earths lithosphere is divided into techtonic plates that move around on top of the asthenosphere

transform boundary

the boundary between two tectonic plates that are sliding past eash other horizontally

divergent boundary

the boundary between two tectonic plates that are moving away from each other

convergent boundary

the boundary between two collidin tectonic plates

constuctive process

happen to the earth that build it up

destructive process

happen to the earth that destroy or break down part of it

lithosphere

layer of relatively cool, rigis rock that includes the crust and the upper most part of the mantle

question

answer

asthenosphere

layaer of softer, weaker rock that can flow slowly like taffy

mesosphere

stronger lower part of the mantle, stiffer rock of this layer extends all the way down to the upper surfaceof the core

outer core

high temps keep the metal liquid. Because of the earths rotation, the flowing iron produces an electric current & create earths magnetic fie

inner core

very high pressure is the most important factor. The inner core is solid

igneous

forms when molten material cools & solidfies either inside or at the surface

intrusive

an igneous rock that forms underground from hardened magma

extrusive

an igneous rock formed earths surface, cools quickly small crystals grainy texture

sedimentary

wind, water, ice, sunlight and gravity all cause rock to weather into fragments

metamorphic

rock is transformed by heat, pressure or chemical reactions, most form under high pressure & temp deep undergound
