A giant, sweaty mosh pit formed at the front of the stage.
At another field site, Dr. Russell pointed out a "kettle hole" -- a pit formed when buried ice melts away.
The shape of the pit formed, due to the photoanodic dissolution of the material, depends on the experimental conditions, notably on the presence or not of Cl− ions in the medium.
A deep but narrow pit formed on the upward tilting port side, while a shallower, broader pit formed on the starboard side, which had mostly been buried by the force of the impact.
A mosh pit formed in the front of the crowd, rife with crowdsurfing, a weird amount of Chief Keef lookalikes making their way out of the woodwork.
It was great, but its chorus of, "I run New York!" rang a bit hollow after she got offstage, the DJ put on A$AP Ferg's "Work," and a mosh pit formed.
The bacteria that feed on the dissolved nutrients had already begun colonizing the new hydrothermal vents at Pele's Pit (formed from the collapse of the old ones), and may be indicators of the kinds of material ejected from the newly formed vents.
The principles of this protection mechanism can be understood and also quantified by means of the scheme and results in Fig. 6: If a corrosion pit forms its local potential or pH differs from that of the majority of the surface.
Following differentiation, osteoclasts resorb bone through a three step process, involving 1) cytoskeletal organization and the formation of a ruffled border membrane, 2) acidification of the resorption pit formed between the osteoclast and the bone surface (Howship's lacuna), which serves to demineralize inorganic bone material, and 3) proteolysis of the organic matrix.
