What is bellow the crust and sto study the earths structure. 1 of 10 How can Siesmic Waves be produced 1) By Earthqukes 2) by setting off a big man made explosion 2 of 10 what can S-waves travel through? 1) The mantle - shows that its a solid 3 of 10 What to P- waves travel faster thorugh? The middle off the core - the inner core 4 of 10 What are S-waves not detected in? the outer core - must be a liquid 5 of 10 how can scientists draw conclusions about about the structure of the earth? 1) measuring the time that it takes for the waves to travel through the earyh 6 of 10 What speed to tectonic plates move a year? 2.5 cm 7 of 10 are tectonic plates more dense or less dense than the mantle? less dense 8 of 10 why are Volcanos and Erthquakes more likley to occur with the movement of tectonic plates? When the plates meet - its the movement of the plates together that causes them 9 of 10 Name the 5 parts that make up the earths structure 1) the crust 2) The lithosphere 3) The Mantle 4) The Solid inner core 5) The liquid outer core 10 of 10
