1	Volcano		_____	Water that contains a high concentration of dissolved salts (mainly sodium chloride).
2	Magma		_____	A fluid or hardened stream or avalanche of mud.
3	Lava		_____	Hot fluid or semifluid material below or within the earth's crust from which lava and other igneous rock is formed on cooling.
4	Pacific Basin		_____	The action of surface processes that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location.
5	Pacific Ring of Fire		_____	Any naturally occurring water except seawater and brackish water.
6	Earthquake		_____	A term used in science that refers to the geological process of rocks breaking apart without changing their chemical composition.
7	Fault Lines		_____	A rupture in the crust of the Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.
8	Plate Tectonics		_____	The breaking down of rocks, soils, and minerals as well as wood and artificial materials through contact with the Earth's atmosphere, water, and biological organisms.
9	Plate Boundaries		_____	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.
10	Uplift		_____	The belt or zone of the continental lithosphere where the extensional deformation (rifting) is occurring
11	Continental Rifting		_____	The sliding down of a mass of earth or rock from a mountain or cliff.
12	Richter Scale		_____	The envelope of gases surrounding the earth or another planet.
13	Salt Water		_____	Vertical elevation of the Earth's surface in response to natural causes
14	Fresh Water		_____	A linear feature that exists between two tectonic plates that are moving away from each other.
15	Weathering		_____	A theory explaining the structure of the earth's crust and many associated phenomena as resulting from the interaction of rigid lithospheric plates which move slowly over the underlying mantle.
16	Physical Weathering		_____	A numerical scale for expressing the magnitude of an earthquake on the basis of seismograph oscillations.
17	Chemical Weathering		_____	Also known as the ecosphere, it is the worldwide sum of all ecosystems.
18	Erosion		_____	The total amount of water that is on the surface of the planet, underground, and in the air.
19	Atmosphere		_____	Hot molten or semifluid rock erupted from a volcano or fissure, or solid rock resulting from cooling of this.
20	Hydrosphere		_____	The erosion or disintegration of rocks, building materials, etc., caused by chemical reactions (chiefly with water and substances dissolved in it) rather than by mechanical processes.
21	Lithosphere		_____	The rigid outer part of the earth, consisting of the crust and upper mantle.
22	Biosphere		_____	Referred to as the “Ring of Fire” due to intense earthquake and volcanic activity occurring near areas of tectonic plate subduction (where one tectonic plate is forced under another).
23	Landslide		_____	also referred to as the Circum-Pacific Belt, is a path along the Pacific Ocean characterized by active volcanoes and frequent earthquakes. The majority of Earth's volcanoes and earthquakes take place along this place.
24	Mudflow		_____	A line on a rock surface or the ground that traces a geological fault.
