They had plenty of time to slowly cool into large crystals in the hot environment at depth. However, some igneous or tectonic process suddenly shoved the magma body up towards the surface. This made the rest of the magma cool suddenly. Because these newer crystals did not have time to grow...
Why does rhyolite have smaller crystals than granite? Why is global biodiversity decreasing? Why does 'like dissolve like'? Why is marine biodiversity higher near coastlines? Why are there more cones than rods near the fovea? Why is there only one primer in PCF? Why do some people have extr...
Granite is acoarse-grained rockcomposed of aluminosilicate minerals that crystallizes slowly and at much higher temperatures than basalt. What are the 3 major types of lava? The high temperatures and pressure under Earth's crust keep magma in its fluid state. There are three basic types of magma...
Many of the things I buy contain little packets of crystals. Some of them actually say "Silica Gel" on them, but many are unlabeled or say something like, "Do not eat." I have found these packets in electronics, vitamins and even in some pepperoni I
Most geodes containclear quartz crystals, while others have purple amethyst crystals. Still others can have agate, chalcedony, or jasper banding or crystals such as calcite, dolomite, celestite, etc. There is no easy way of telling what the inside of a geode holds until it is cut open or ...
Obsidian consists of approximately 70% or more of the silicone (silicone dioxide) that has been uncristallised. It is like granite and rhyolite, which were also initially frozen, chemically. As obsidian is not mineral crystals, it is not a real “stone” technically obsidian. It is actually ...
For most of its life prior to extinction, a volcano is in a dormant stage where it does little more than stand as a mountain or large hill in the landscape. When it wakes, it erupts. Eruptions can involve spewing lava, ash, smoke, gasses, chunks of rock, and volcanic glass....
the crust is anomalously thick, and rocks associated with continents (rhyolite, granite) are found in the ocean (seemingly out of place). The study demonstrates just how different Iceland and the Hadean really are, but how similar the Hadean may have been to other environments that are more ...
If it turns out the canteen staff, receptionists, and maintenance staff do really well on predictions then great, but how often does that happen versus “the best predictors are the guys already doing this stuff anyway”? What I mean is, the more and better information you have, and the ...
