Mount Everest is still growing by a few millimetres every year.
The Indian tectonic plate is pushing into the Eurasian plate at about five centimetres a year, and the Himalayas are being squeezed upward as a result. Everest's official height was revised to 8,848.86 metres in 2020.
Why is this true?
Erosion and earthquakes work against the uplift; the 2015 Nepal earthquake may have shifted the summit slightly. The rock at the very top is marine limestone, formed on an ancient sea floor.

Science and nature supply facts that feel like they break the rules until you see the mechanism. Hot water freezing before cold, glass that flows, lightning hotter than the surface of the Sun. Each entry keeps the physics or chemistry short and readable, states plainly where the effect is still debated, and links to a source for anyone who wants the full derivation rather than the headline.
