Why does the frost depth increase when the surface temperature warms up?
Weather & ForecastsThe Frost Paradox: When Warmer Weather Deepens the Freeze (Yes, Really!) Okay, picture this: It’s getting warmer, right? So you’d think the ground would start to thaw. Makes perfect sense. But here’s a head-scratcher: sometimes, a warming trend actually makes the frost go deeper into the ground. How messed up is that? It sounds totally
Is there a software or means that can generate piper diagrams without some data?
Data & AnalysisOkay, here’s a revised version of the blog post, aiming for a more human and conversational tone: Piper Diagrams from Thin Air? When Your Water Data Isn’t Quite “All There” Piper diagrams – those cool-looking triangular charts – are a hydrochemist’s best friend. They’re fantastic for quickly visualizing and understanding the chemical makeup of water,
How is surface pressure generally measured, and at what actual height?
Earth ScienceAsked by: Jenny Robinson How do you measure surface pressure? Calculate surface pressure: P=F/A The force is distributed over the entire bearing surface. All that’s left to do is to divide the force by the calculated area to get the surface pressure. Which height is a measure of atmospheric pressure? One atmosphere (101.325 kPa or
Is the iron on Earth’s crust a leftover of the Iron catastrophe, or it was brought back by volcanoes?
Earth ScienceAsked by: Jenny Robinson So Iron is indeed a leftover of the iron catastrophe, and the reason why that fraction didn’t sink is because it was oxidized. Where did the iron in the Earth’s core come from? Billions of years ago, the newborn Earth morphed from a messy ball of mixed-up rock to a perfectly
