Show WORRY ABOUT THIS WHY ARE THEY HOT The present accepted theory of ot geyser geyser gey ser action dating back in its inception about 85 years must be modified in a number of points Dr E. E T. T Allen of the Carnegie Institution of ot Washington Washing Washing- ton believes The classic theory has been that water wa wa- wa ter flowing Into the eYser tube or well becomes heated at at the bottom by volcanic steam from below finally becoming superheated and flashing into a steam explosion when a little water at the top slops over But Dr Allen points out that not all geysers slop over before they erupt Furthermore many geysers have hotter water way half down dONIl their wells than they have at the tho bottom This points strongly at a probability of ot the heating steam or gases coming in iTt from a side source instead of from the bottom It seems likely also that some geysers geysers gey gey- sers get not only steam but at least some of their hot water as well from side sources This is evidenced by the measurement of the amount of water discharged during an eruption which with some geysers amounts to a great deal more than the well isel will hold s tl |
