Most of the emissions of greenhouse gases (GHG) come primarily from burning fossil fuels (coal, hydrocarbon gas liquids, natural gas, and petroleum) for energy use and the major greenhouse gas is of course carbon dioxide (CO2) which comes from burning fossil fuels and land-use change.

But methane (CH4) and nitrous oxide (N2O), which mostly come from agriculture and waste, are also significant GHGs and shouldn't be discounted.

Geysers are fountains of hot water and superheated steam that erupts with an explosion whereas hotsprings or thermal springs are found where water sinks deep enough the surface to be heated up by the interior forces and it comes out without any explosion. Iceland and New Zealand are the other countries having geysers while hot springs are relatively common.
