FULGURITE from Morocco. A fulgurite is a hollow, tubular piece of fused sand caused by a lighting strike to the ground. They are hollow and lined with melted sand grains and generally less than an inch or two in diameter ( a lighting bolt is normally 1 to 2 inches in diameter). Fulgurites mark the pathway the lighting followed into the ground.
So hiring a white person with a criminal record is more desirable than hiring a Black person without one? Never would’ve guessed…
this is what we mean when we say ALL white people have white privilege. whether you’re rich, poor, a criminal, uneducated or anything else. a white criminal has a better chance at getting a call back then a black person with no criminal record. shut the fuck up next time you wanna talk to us about privilege.
“The Wave” located in Arizona near the Utah border in the USA is a colourful rock formation made of sandstone. Initially formed in the Jurassic period by migrating sand dunes the sandstone has since been eroded into this spectacular shape.
Eroded firstly through rainwater runoff sourced from a drainage basin nearby. The rainwater followed the path of least resistance along weak points such as joints and fractures creating the U-shaped troughs as the sediment washed away.
Secondly after the shrinkage of the drainage basin wind became the predominant force of erosion. Over time this created the wave features as the wind was naturally funneled through the troughs. The orientation of the erosional steps and risers show the superior wind direction over the millions of years of erosion. The ribbing that is visible is due to slightly different types of sandstones making up the formation, some more compacted and/or harder than others thus harder to erode so stick out over the weaker types.
Interestingly there have been trace fossils of various types of Jurassic dinosaurs and other desert dwelling creatures of the time found in the formation.

Around 20 earthquakes were measured last night in the Bárðarbunga area between 00 and 06:30; this is about half the number of events detected during same period yesterday.
The largest events occurred just after midnight (00:07:38, M5.3) at southern caldera rim of Bárðarbunga and around five o’clock (05:00:38 of M4.3 and 05:04:49 of M3,0) at the northern rim of Bárðarbunga.
