But… why? And what actually is a volcano, anyway? Geologically speaking, a volcano is a crack in the ground— AKA a vent— that lava comes out of.It can also refer to the land formations that build up around those vents, like the mountain-looking things we might think of when we hear the word “volcano.”
I didn’t understand the craze until I saw yours, but, like, I kinda get it now. And geologically speaking, it’s kind of a big deal. Water has shaped Earth’s landscape for billions of years.
So, yeah — there are lots of cultural, political, and environmental factors at play when choosing a lab-grown or a natural diamond. But geologically speaking? They’re one and the same. Whether grown in a lab or blasted from the earth’s mantle, diamonds are a part of our world.
And all the bite marks are on one bone, the humerus, the upper arm bone. somewhere where geologically we know it's the right age and it's the right kind of rock and ideally fossils have been reported from there
And they get their various energy quantum by quantum by doing things like oxidizing metals in minerals. So this is a geologically driven source of energy for these organisms. And as we look around our solar system, we see nowhere else that is green and gooey like our planet.
But all those things are good. not expect a small planet on the fringes of the solar system to be so geologically active and diverse and vibrant,
went wrong in the worst periods in Earth's history. So there's five times in the last 559 million years where the majority of animal life goes extinct in a geologically brief period of time. So at most, we now know from fine scale geochronology, these events took place over a few tens of thousands of years.
So I think if you warm eventually, things can migrate and track their preferred temperature. But yeah, the Earth system can't keep up with really geologically sudden chemistry changes. So even if we injected carbon dioxide, thousands of gigatons of carbon dioxide over a million years,
And each of these different Earths represents wildly different conditions that the planet has passed through. But what we have been living in, in the last 10,000 years, which geologically is not that long, is the Holocene. And here is a record of temperature.
of revolutionized again the understanding of Mars because it means that either there's life down there. 90% of methane on Earth comes from biological sources. Doesn't mean that this is necessarily biological but it would, if it's not biological, then that means Mars still is geologically alive which everyone also assumed was not possible, that it had died long ago. So methane on Mars is, is one of the major breakthroughs and it, going back
One is its, increases the cost of coal-fired power by half or so. It doesn't work everywhere. It has to have the right geology in the ground to do this and most coal plants were not built with the idea that we need to store carbon, so they're not built geologically in the right place. So, you have to pipe the stuff, which is again, all the headaches of piping and all that kind of thing and cost of that. And you have an entrenched industry that basically
