Volcano's 3rd nine weeks

Question Answer
volcano a mountain or hill, typically conical, having a crater or vent through which lava, rock fragments, hot vapor, and gas are
lava hot molten or semifluid rock erupted from a volcano or fissure, or solid rock resulting from cooling of this.
magma hot fluid or semifluid material below or within the earth's crust from which lava and other igneous rock is formed by cooling.
magma chamber A magma chamber is a large underground pool of liquid rock found beneath the surface of the Earth.
lava flow a mass of flowing or solidified lava.
volcano ash Image result for volcanic ash definition
Volcanic Ash is defined as very small solid particles ejected from a volcano d
ring of fire The Ring of Fire is an area in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur
pipe volcanic pipe. A vertical conduit below a volcano through which magma has passed and that has become filled with solidified magma, volcanic breccia, and fragments of older rock. The American Heritage® Science Dictionary.
vent an opening, as in a wall, serving as an outlet for air, smoke, fumes, or the like. 2. an opening at the earth's surface from which volcanic material, as lava, steam, or gas, is emitted.
crater the bowl-shaped depression around the orifice of a volcano b : a depression formed by an impact (as of a meteorite) c : a hole in the ground ma
elements i.e. the same atomic number. Elements are chemically the simplest substances and hence cannot be broken down using chemical methods. Elements can only be changed into other elements using nuclear methods
viscosity Viscosity is a measure of the resistance of a fluid to deformation under shear stress.
silica Medical Definition of silica. : the dioxide of silicon SiO2 that is used as an ingredient of simethicone and that occurs naturally in crystalline, amorphous, and impure forms (as in quartz, opal, and sand respectively)—called also silicon dioxide.
pahoehoe One, pahoehoe, refers to lava with a smooth, shiny, or swirled surface
aa basaltic lava forming very rough jagged masses with a light frothy texture.
compund Definition of Compound. A compound is a substance formed when two or more chemical elements are chemically bonded together. Two types of chemical bonds common in compounds are covalent bonds and ionic bonds.
suduction In geology, subduction is the process that takes place at convergent boundaries
dike A dike is an intrusion into an opening cross-cutting fissure, shouldering aside other pre-existing layers or bodies of rock; this implies that a dike is always younger than the rocks that contain it.
magma hot fluid or semifluid material below or within the earth's crust from which lava and other igneous rock is formed by cooling.
batholith a very large igneous intrusion extending deep in the earth's crust
extinct (of a species, family, or other larger group) having no living members.
active (of a person) engaging or ready to engage in physically energetic pursuits.
caldera a large volcanic crater, typically one formed by a major eruption leading to the collapse of the mouth of the volcano.
geyser a hot spring in which water intermittently boils, sending a tall column of water and steam into the air.
shield volcanos a broad, domed volcano with gently sloping sides, characteristic of the eruption of fluid, basaltic lava.
lava plateaus Lava plateaus are formed by highly fluid (runny) basaltic lava during numerous successive eruptions through numerous vents without violent explosions (quiet eruptions).
landforms a natural feature of the earth's surface
dome moutains a mountain range resulting from dissection of a structural dome (as the Black Hills in South Dakota) —called also domal mountain
hot springs a spring of naturally hot water, typically heated by subterranean volcanic activity.
geothermal energy Geothermal energy is thermal energy generated and stored in the Earth. Thermal energy is the energy that determines the temperature of matter.
