How does quartz form in calcite veins?
Earth ScienceAsked by: Chris Follette Under normal temperature-pressure conditions silica / quartz precipitates or dissolves extremely slowly, but at higher pressures and temperatures the kinetics of crystallization are dramatically accelerated. So precipitation of quartz and calcite is actually quite common. How is a quartz vein formed? The simplest type of a quartz vein is the filling
Would oceans regenerate if removed?
Earth ScienceAsked by: Debbie Contreras Does the earth make new water? Over millions of years, much of this water is recycled between the inner Earth, the oceans and rivers, and the atmosphere. This cycling process means that freshwater is constantly made available to Earth’s surface where we all live. Volcanoes release massive amounts of water from
Is there open scientific analysis of the proposed discharge of water from Fukushima?
Energy & ResourcesFukushima Water Discharge: What’s Really Going On? Okay, let’s talk about Fukushima. It’s been over a decade since that horrific earthquake and tsunami in 2011, the one that crippled the Fukushima Daiichi Nuclear Power Station. Ever since, they’ve been dealing with a monumental problem: what to do with all the water used to cool the
Does this optical phenomenon have a name?
Earth ScienceAsked by: Jana Kemp What is the name of the optical phenomenon? A halo (ἅλως; also known as a nimbus, icebow or gloriole) is an optical phenomenon produced by the interaction of light from the sun or moon with ice crystals in the atmosphere, resulting in colored or white arcs, rings or spots in the
What is solidus and liquidus temperature of granite?
Earth ScienceAsked by: Jana Kemp The liquidus and solidus temperatures are 925-665 C (initial4.5%H2O), 750-630 C. What is solidus and liquidus temperature? Simply put, liquidus is the lowest temperature at which an alloy is completely liquid; solidus is the highest temperature at which an alloy is completely solid. Pure metals are fluid, and they melt at
Volcanic Explosivity Index of Cumbre Vieja eruption
Earth ScienceAsked by: Delfeayo Mazatan Is a VEI 9 eruption possible? It is possible that evidence for a VEI 9 eruption exists and is buried in the geologic record. Eruptions that large would be very rare events, but it is impossible to say that eruptions that large have never occurred. What was the last VEI 8
