that's why jackie kendrick studied help or kind of grok so rather against each other until the mel. this is something that happens when you rub your hands together on a cold day and you see this is also true of trucks. this happens in tectonic prices, and it also happens that volcanoes. and so here when we move on to some post past one, another rich, the simulates a more of these frictional context. so we want to understand what kind of promotions create what levels of heat inside of the results was captured on video. it takes just a 2nd for the rock to mount. so at the beginning, when we have flip, we're going to see this kind of ash that creates it from the folks at the same. and you can see that from the house from the surface. and then very quickly, we're reaching a couple of 100 degrees and then already a 1000 degrees where we start nothing. it can reach up to 1400 degrees through a friction alone as this thermal image shows. that this is quite remarkable. and this is not something that we were actually expecting when we think maybe the most risky is not going straight into tou

so jackie kendrick and her team discovered that the friction doesn't just generate more heat . it also helps all kind of rupture. as the molten maxima rises, the pressure goes down that allows the gases in the maxima to expand. the gas is phone bubbles, and that increases the volume of the maxima. well, decreasing it's density, that gives the maximum momentum. finally reaches the stuff is why it's called lava . so it's the same as a bottle of champagne. and if you happen to open it too quickly, it splashes everywhere. and every time we open a bottle of sun panel, but of coca cola, we try to regulate that with our hands. we do this systematically on of us every day. so could we do the same with the magma? could we drill in a way, way we could control the gas coming out, so we prevent eventually prevent eruption from happening. young. i'm on a and his team wants to put those questions to the test at the cross landmark move testbed in iceland planning to drill a to kilometer long, not much chained to upset the maxima wave. it's normally hidden from view. and the hoping to figure o

that's why jackie kendrick studied help or conic rock. so rather against each other until they melt. this is something that happens when you rub your hands together on a cold day, and you see this is also true of trucks. this happens in tech 20 cars prices and it also happens at volcanoes. and so here when we move on to samples, task one, another richly simulates one of these frictional context. so we want to understand what kind of emotions create what levels of heat inside of the result was captured on video. it takes just a 2nd for the rock to mount. so at the beginning, when we have split, we're going to see this kind of ash that's created from the folks at the same. and you can see that from the house from the surface. and then very quickly, we're reaching a couple of 100 degrees and then already a 1000 degrees where we start melting. it can reach up to 1400 degrees through friction alone as this thermal image shows. that this is quite remarkable. and this is not something that we were actually expecting when we pick out for maybe th
