3rd quarter science

• volcanism - any phenomenon of erruption of molten lava
• vulcano - burning mountain
• vulcan - roman god of fire
• volcano - hill, mountain, fissure from molten rocks
• convergent plate boundaries - magma is abundant in subduction zone
• pacific ring pf fire - encircling the pacific ocean
• divergent plate boundaries - oceanic ridge system
• hot spots - within a rigid plate
• shield volcano - broad , slightly domed structure
• cinder cone volcano - built from ejected lava fragments, most abundant out of the three volcanoes
• composite volcano - stratovolcano, nearly perfect slope
• magma chamber - large reservoir that stores magma prior to erruption
• magma - extremely hot liquid and semi liquid rock
• main vent - where magma passes through
• secondary vent - alternative smaller outlet
• lava - semi fluid rock errupted
• crater - bowl shaped depression
• ash - mixture of rocks, minerals, and gas
• phreatic - steam driven
• vulcanian - short, explosive, and violent, tall eruption, highly viscous magma
• strombolian - weak to violent, fountain lava
• pelean - glowing avalanche rapidly moves
• phreatomagmatic - water and magma
• plinian - most violent amongst all volcanic erruptions
• monsoon - seasonal shift
• amihan - northeast monsoon, november-april
• habagat - southwest monsoon, may-october
• global warming - gradual increase of the temperature of the atmosphere
• el nino - warming of coastal waters
• la nina - cooling of ocean surface
• tropical cyclone - rapid rotating storm
• hurricane - type of tropical cyclone
• typhoon - a mature tropical cyclone
• latitude - distance from the equator
• prevailing winds - the wind direction
• altitude - height above sea level
• distance from the sea - ocean and seas heat up and cool down longer than land
• star - luminous ball of gas
• size - affects the brightness of the star
• mass - "stellar mass" , used to describe the mass of the star
