GeographyRock landscapes and processesGCSEAll boards Created by: Annie Laura RichardsonCreated on: 05-11-11 17:45 What is atmosphere? layers of gases which make up the air around us 1 of 34 what is hydrosphere? layer of water- sea,lakes,rivers,groundwater and ice on the earths crust 2 of 34 what is biosphere? thin layer of living things- plants,animals living on the earths crust 3 of 34 what is geosphere? rocks of the earths crust and deeper into the earth towards the core 4 of 34 what is the name of the crust and upper mantle? lithosphere 5 of 34 under the upper mantle there is a goo like substance called? asthenosphere 6 of 34 in the earths layers, the rock cycle is otherwise known as? convection 7 of 34 what is the outer and inner core made of? iron and nickle 8 of 34 Oceanic can sink/be pushed into the mantle? True 9 of 34 continental makes continents and is made of granite? True 10 of 34 a destructive plate boundary... has oceanic crust that moves towards continental crust 11 of 34 a collision margin is when... plates move together, both continental crust 12 of 34 constructive is where? plates move apart 13 of 34 conservative plates.. slide past eachother 14 of 34 why is the inner core so hot? because molten lava is spewing from active volcanoes, it shows its hot inside the earth which is caused by radioactive decay of elements in the core 15 of 34 why doesn't the inner core melt? its under too much pressure and theres no room for it to melt 16 of 34 what creates northon lights? charged particles hit the earths magnetic field which bounce off creating colours which are the northon lights 17 of 34 what is the outer core? metal liquid that moves around creating a magnetic field around the world which protects us from the suns atems 18 of 34 all volcanoes are found at plate edges? False 19 of 34 volcanoes can be found at plate edges, destructive, constructive and hotspots? True 20 of 34 what is a hotspot? places where the earths crust is thin 21 of 34 classify an active volcano? recently erupted(200 years), likely to erupt again 22 of 34 dormat volcanoes? erupted with historic times (last 2000 years) 23 of 34 extint volcanoes? has not erupted in historic times and wont erupt again 24 of 34 basic lava is runny and hot 1200 c? True 25 of 34 acidic lava has less eruptions but more violent due to gases? True 26 of 34 basic lava found at constructive plate boundaries and hot spots? True 27 of 34 acidic lava is found at destructive margins where oceanic crust is destroyed ? True 28 of 34 shield volcanoes have gently sloping sides? True 29 of 34 composite volcanoes have steeper sides? True 30 of 34 moniter shape of volcano tiltmeter 31 of 34 short term responses to earthquake impacts? emergency water supplies,sniffer dogs, tempory houses 32 of 34 earthquake starts at a focus which is... the point of energy release in the crust 33 of 34 epicentre is first to get shaken, on suface above focus? True 34 of 34
