What is a plate boundary in science?
GeologyA plate boundary is a three-dimensional surface or zone across which there is a significant change in the velocity (speed or direction) of motion of one lithospheric plate relative to the adjacent lithospheric plate. What is plate boundary short answer? Also called lithospheric plate. site of tectonic plates sliding next to each other in opposite
What is long hole stoping?
GeologyLong hole stoping as the name suggests uses holes drilled by a production drill to a predetermined pattern as designed by a mining engineer. Long hole stoping is a highly selective and productive method of mining and can cater for varying ore thicknesses and dips (0 – 90 degree). What is long hole open stoping?
What plates caused Mt St Helens to erupt?
GeologyMount St Helens is located on a destructive plate boundary where two plates are squeezing towards each other. The eruption was caused by the ocean crust (Juan de Fuca plate) subducting under the continental crust (North American plate). The ocean crust was destroyed and formed magma which rose to the surface. What caused Mount St.
What is a composite volcano made of?
GeologyComposite cones are large volcanoes (many thousands of feet or meters tall) generally composed of lava flows, pyroclastic deposits, and mudflow (lahar) deposits, as well as lava domes. Composite volcanoes are active over long periods (tens to hundreds of thousands of years), and erupt periodically. What materials make up composite volcanoes? Composition. Composite volcanoes—also called
What type of plate boundary is the Cocos Plate?
GeologyThis subduction-subduction-transform (SST) triple junction is referred to hereafter as the NACC triple junction. Off the Pacific coast, the Cocos plate is subducted beneath both the North American and Caribbean plates, which are separated by a sinistral transcurrent boundary. Is the Cocos Plate convergent or divergent? Compared to the other tectonic plates in the region,
What is weathering in short answer?
GeologyWeathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. What is weathering mean for kids? Weathering is the process where rock. is dissolved, worn away or broken down into smaller and smaller
What happens when plates move apart?
GeologyA divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface, solidifying to create new oceanic crust. The Mid-Atlantic Ridge is an example of divergent plate boundaries. What is it called when plates move apart?
Was Ventura affected by earthquake?
GeologyShaking was felt throughout the Ventura County region as well as various parts of Los Angeles County. No injuries or damage have been reported. USGS initially reported the quake as a magnitude 3.9 before upgrading it to 4.1, then adjusting it to 4.0. Did Ventura have an earthquake last night? An earthquake shook parts of
What damage did Mt St Helens cause?
GeologyHundreds of square miles were reduced to wasteland, causing over $1 billion in damage (equivalent to $3.5 billion in 2020), thousands of animals were killed, and Mount St. Helens was left with a crater on its north side. What problems did Mt St Helens cause? Helens’ vicitims died by asphyxiation from inhaling hot volcanic ash,
