Most of the crustal material on Earth is the product of partial melting of the mantle that produces basaltic melts16,17. Basaltic melts are produced mostly by decompression melting along mid-oceanic ridges in the upper mantle. However, both geophysical and geochemical evidence also suggests the ...
Night-time provides a critical window for slowing or extinguishing fires owing to the lower temperature and the lower vapour pressure deficit (VPD). However, fire danger is most often assessed based on daytime conditions1,2, capturing what promotes fire
The most common vegetation type on earth—grassland—is often agricultural in usage. Many are either directly grazed, or, as is the case for the most productive ones, harvested for hay which is then consumed when pasture is no longer growing enough to support cattle or sheep. Rapidly increasin...

Famous trees come and go. L'Arbre du Ténéré was once considered the most isolated tree on Earth, a landmark on caravan routes in the Sahara, until it was knocked down by a drunk Libyan truck driver in 1973. This year in August, the famous Anne Frank t
The change in density also causes the waves to follow curved paths as they move through the Earth. As waves travel into more dense material, they speed up and curve. The curving of these waves is similar to the refraction* that occurs when a light ray passes through an interface between...
