Igneous rocksform when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust. ... Intrusive rocks are formed from magma that cools and solidifies within the crust of the planet. What are the 3 ways...
Molten magma running through these pipes usually reaches the surface as lava and cools off, but if it doesn’t reach the surface, it cools more slowly, crystallizes, and forms coarse-grained minerals. The first type of rock, igneous rock, is also formed by the cooling and crystallization of...
With over a dozen lectures on things like Palos Verdes Barite, Agates of the Western USA, Rockhounding 101 and such, the talk that put butts into seats was my talk on Fakes and Forgeries. Here is that lecture, in fact, redone in 2023 for a new life on the internet. I had joined...

Does lava come from the center of the Earth? Lava (which as you undoubtedly know, is partially molten rock erupted by volcanoes) typicallycomes from the mantle—the Earth's middle layer, sandwiched between the crust and the core. Once it reaches the surface, lava quickly cools down and soli...
These processes must have evaporated part of the Earth and what remained was molten at least several hundred kilometers down, removing the water. Until now, scientists did not know a stable compound that could lock up hydrogen and oxygen atoms within the planet’s interior long enough and then...
From there, you’ll build the first Cryo plant – no production bonus but does have 8 mod slots. From there it’s a rather small jump to a lithium plant, then to fluo liquids, cryo science, quantum chips, and finally fusion power. Never had a power issue this time, which was gloriou...
Where other authors might fill in factual gaps by inserting their own opinions, Curtis does the real work. His research is nothing short of awe-inspiring: In addition to deeply mining every available source out there, he also tracked down all the research Dardis had gathered from MGM, which ...
There are 2 other late game parts I can tackle (they are still red gates, indicating higher difficulty) that I’m partially through, and are distinctly in the ‘want’ category. The mechanical portion doesn’t interest me here, the story does, which I think speaks volumes to the remainder...
