Some seafloor microbes can take the heat: And here’s what they eat
It’s cold in the depths of the world’s oceans; most of the seafloor is at a chilly 4°C. Not so the seafloor of Guaymas Basin in the Gulf of California. Here, tectonic plates drift apart and heat from Earth’s interior can rise up — so far up that it bakes large areas of the seafloor […]
Possible chemical leftovers from early Earth sit near the core
Let’s take a journey into the depths of the Earth, down through the crust and mantle nearly to the core. We’ll use seismic waves to show the way, since they echo through the planet following an earthquake and reveal its internal structure like radar waves. Down near the core, there are zones where seismic waves […]
