Is the earth's diameter increasing with time?

…If you add the increase in weight - then the weight needs to come from somewhere - because according to Newtonian physics matter can neither be created nor destroyed. So if external matter enters the Earth (hopefully not because that would mean asteroid collisions) it depends on the angle and speed of impact that would deliver the speed to the rotation of the axis. It could in theory land in a certain way that would stop the spin of the Earth or reverse it…

At least 5 metric tonnes of cosmic dust enters earth’s atmosphere every day. It can, perhaps, increase Earth’s radius by 1mm in a few hundred years
