Venezuela's Angel Falls plunges about 979 m from the edge of a sandstone plateau, more than 800 m of it in a single uninterrupted drop. It is the tallest continuous waterfall on land, nearly twenty times the height of Niagara Falls. The water falls so far that some of it turns to drizzle before reaching the foot of the cliff.
On 27 August 1883, the eruption of the Indonesian volcano Krakatoa was heard as far away as Rodrigues Island, nearly 4,800 km away. Its pressure wave was picked up by barometers worldwide and circled the globe several times. The tsunamis that followed killed more than 36,000 people.
The deepest known point in the ocean, Challenger Deep, lies roughly 10,900 m below the Pacific surface. Drop Everest in and its summit would still sit about 2 km underwater. Down there, the pressure is more than 1,000 times what you feel at sea level, roughly a tonne pressing on every square centimetre.
