1. Helium can also work against gravity?
Diamonds are undoubtedly the Milky Way galaxy’s best friends. Studies have examined the potential that Neptune, Uranus, Jupiter, and Saturn have to be compelled to produce diamonds. The atmospheres in all four planets have such extreme pressure that they'll crystalize carbon atoms and turn them into diamonds. Scientists were able to produce the proper conditions during a laboratory to prove this happens on Neptune and Uranus. Separately, a different group of researchers speculates that it's going to rain as much as 2.2 million pounds of diamonds on parts of Saturn each year––this is definitely the richest of our science facts!

Tiny single-celled algae known as coccolithophores have lived in Earth’s oceans for two hundred million years. unlike any other marine plant, they surround themselves with minuscule plates of calcite (coccoliths). slightly below one hundred million years ago, conditions were just right for coccolithophores to accumulate during a thick layer coating ocean floors in a white ooze. As further sediment built up on high, the pressure compressed the coccoliths to create rock, making chalk deposits like the white cliffs of Dover. Coccolithophores are just one of the many prehistoric species that are immortalized in fossil form, however, how will we know how old they are? Over time, rock forms in horizontal layers, leaving older rocks at the bottom and younger rocks close to the top. By learning the type of rock within which a fossil is found paleontologists will roughly guess its age. carbon dating estimates a fossil’s age more precisely, based on the speed of decay of radioactive elements like carbon-14.

When He is cooled to extreme temperatures, simply a few degrees away from absolute zero (-460˚F or -273˚C), it turns into a superfluid, which means it will flow without friction. It will climb up and over the sides of a glass. It will leak through molecule-think cracks during a container. If it starts flowing like a fountain, it'll never stop.

The Earth’s crust is split into gigantic pieces known as tectonic plates. These plates are in constant motion, propelled by currents within the Earth’s upper mantle. Hot, less-dense rock rises before cooling and sinking, giving rise to circular convection currents that act like big conveyor belts, slowly shifting the tectonic plates higher than them. Hawaii sits within the middle of the Pacific Plate, that is slowly drifting north-west towards the North American Plate, back to Alaska. The plates’ pace is comparable to the speed at that our fingernails grow.
