At https://phys.org/news/2021-11-sun-unaccounted-source-earth.html … an interesting new study – the Sun might be an unaccounted source of water on earth. See www.nature.com/articles/s41550-021-01487-w … a University of Glasgow led international team found the solar wind created water on the grains carried on asteroids that smashed into the earth during the early period of the solar system. The source of water on earth is an ongoing research project. This, the latest theory, claims there are 20L in every square metre of rock with an origin in asteroids. Does this include rocky comets?
Over at www.ncgtjournal.com … the latest issue of their journal is now available to view. It has some interesting papers on solar wind and plasma and how it might cause tectonic events on the surface. Some deep research is involved.
