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 is the difference between a rock and a mineral quizlet?
GeologyWhat is te difference between rocks and minerals? Minerals have only one substance, but rocks have two or more minerals. Therefor, a rock can be broken in half but a mineral cannot because of it’s one substance. What is the difference between a rock and a mineral? A mineral is a naturally occurring substance with

What are the similarities and differences between continental and oceanic crust?
GeologyOceanic and Continental crusts are alike because they both shift and move and grow. They differ by there rock types. Oceanic crust is made up of dense basalt while continental crust is made up of less dense granite. What is the similarities and differences of oceanic and continental crust? Continental crust is low in density
