Moon
Up to 14.000 square kilometers of the Moon's surface may remain in perpetual shadow.
Water is most likely to be present in these places.
Snow
Snowflakes fall relatively slowly, at about four kilometers per hour.
On average, heavy rainfall falls at about 20 kilometers per hour, and hail can reach much higher spe ...

Beyond Earth, lava can reach even higher temperatures; the record holder is Io, Jupiter's moon, where satellites have recorded lava flows with an average temperature of 1,300 °C (2,370 °F).

Physical activity is equally important for the proper functioning of the brain, as it helps to create new nerve connections.
Medium-intensity aerobic exercise is considered the most effective.
