7135622610	mantle	The layer of hot, solid material between Earth's crust and core. contains magma	1
7135622862	magma	molten rock	2
7135623063	asthenosphere	The layer of Earth located in the outer part of the mantle, composed of semi-molten rock.	3
7135623602	lithosphere	A rigid layer made up of the uppermost part of the mantle and the crust.	4
7135623769	crust	The thin, outermost layer of the earth, or the uppermost part of the lithosphere.	5
7135624182	hot spot	a place where molten material from Earth's mantle reaches the lithosphere	6
7135625524	plate techtonics	theory that explains how huge blocks of Earth's crust called "plates" move	7
7135626290	Tectonic cycle	the sum of the processes that build up and break down the lithosphere	8
7135626602	subduction	process by which one tectonic plate slips beneath another tectonic plate	9
7135626836	volcano	A vent or fissure in the Earth's surface through which magma and gases are expelled	10
7135629042	divergent plate boundary	An area beneath the ocean where tectonic plates move away from each other.	11
7135629230	seafloor spreading	Formation of new oceanic crust due to the upwelling of magma at mid-ocean ridges.	12
7135629486	convergent plate boundary	An area where plates move toward one another and collide.	13
7135629744	transform fault boundary	an area where tectonic plates move sideways past each other	14
7135629908	fault	A break or crack in Earth's lithosphere along which the rocks move	15
7135630050	seismic activity	The frequency and intensity of earthquakes experienced over time	16
7135630378	fault zone	A large expanse of rock where a fault has occurred.	17
7135630650	earthquake	sudden violent shaking of the earth's ground caused by movement of the crust	18
7135630864	epicenter	Point on Earth's surface directly above an earthquake's focus	19
7135631149	Richter scale	a scale that measures the largest ground movement that occurs during an earthquake	20
7135631277	rock cycle	the series of processes that change one type of rock into another type of rock	21
7135632139	igneous rock	rock formed when magma or lava cools and hardens	22
7135632571	intrusive igneous rock	rock formed from the cooling and solidification of magma beneath Earth's surface	23
7135632915	extrusive igneous rock	rock that forms from the cooling and solidification of lava at Earth's surface	24
7135633153	fracture	a crack that occurs in rock as it cools	25
7135633962	sedimentary rock	rock formed when particles of rock and organic material are pressed and cemented together	26
7135634191	metamorphic rock	rock that has changed as a result of heating and pressure	27
