Replying to Landing jumps from a height

Hey guys, newbie freestyle skier here.

I've only done maybe about a quarter of a season of jumps and sliding boxes. Before that I had an 8-year gap of no skiing and even before that I was just general skier, maybe intermediate level. I am still very much a novice; only done small to medium straight air jumps. Half the time I'd approach the jump with too little speed in fear of "over jumping" and so just end up landing on the flat part right before the ground starts curving downhill.

I see videos of people doing jump tricks all the time, flying up maybe about 10+ feet into the air. That is about the height of my roof. Today I was up there and I look down and I wonder how do those skiers not land with their ankles crushed and poking right through the soles of their feet? How do you land from that height and not suffer extreme injuries?

Is landing on the "sweet spot" at an angle down the hill really supposed to remove that much of the force? Or am I really just supposed to "get used to it" and grow steel ankles?

Any help to understand this would be appreciated!
