Based on the given picture above, I can say that this kind of rock is what we call a PRECARIOUS BOULDER, or in simpler terms, it is called a BALANCING ROCK. It is a geological formation that occurs naturally. This can be found in several parts of the earth. How the rock is kept balanced on its tiny pedestal is that it is firmly attached to a base rock or a stem.
It will most likely get hotter and hotter and eventually exsplod from all the presure.
Float, its to light there's not enough denisty to bring it down
If an airplane is flying at 300 km/h to the east and is facing a headwind of 18.0 km/h, the final velocity can be calculated using simple vector addition. In this case, the planes velocity is positive (+330 km/h) and head wind has a negative component (-18.0 km/h). Vector addition yields +330 km / h + (-18.0 km /h) = 312 km / h.
