What a ball of rock
Concretions are hard lumps found in sedimentary rock and often confused with fossils. They form during the long complex set of processes known under the umbrella term diagenesis, whereby the deposited sediments gradually turn into rock as more and more sediments pile up above increasing the pressure and temperature below. This process is further complicated by expulsion of water, and the passage of mineral rich waters from deep under the sedimentary stack.

Reykjavik, Iceland turned of all its city lights for one hour on the night of Sept. 28 to make it easier to see the Northern Lights. The stunning light display is caused by electrically charged particles from the sun crashing into Earth’s atmosphere. (📷 : Getty)

Lava flows like these Hawaii’an ones are endlessly mesmerizing. This type of flow is gravity-driven; rather than being pushed by explosive pressure, the lava flows under its own weight and that of the lava upstream. In fact, fluid dynamicists refer to this kind of flow as a gravity current, a term also applied to avalanches, turbidity currents, and cold drafts that sneak under your door in the wintertime. How quickly these viscous flows spread depends on factors like the density and viscosity of the lava and on the volume of lava being released at the vent. As the lava cools, its viscosity increases rapidly, and an outer crust can solidify while molten lava continues to flow beneath. Be sure to check out the full video below for even more gorgeous views of lava. (Image/video credit: J. Tarsen, source; via J. Hertzberg)
