  Earthquakes and volcanoes are what happens when tectonic plates that make up the earth’s core/mantle bash into one another and slide past each other – I’m not an expert on these!. Things like the train line happen due to land slides…….these can be caused as a result of earth quakes, but they can also happen for many other reasons such as a side effect of the vibration of the trains on the tracks, heavy rainfall, change in land use at the top of the embankment etc.
  
  Transparent soil is ‘fake’ soil – you can’t build a building or anything on it, but it behaves like a clay when you put a weight on it! It’s made from a few ingredients in the labs!
