Ski cross is under freestyle skiing, i imagine snowboard cross would come under snowboard http://en.wikipedia.org/wiki/Freestyle_skiing_at_the_2014_Winter_Olympics
Luge and Skeleton are somewhat similar to bobsledding, except it's just one person, on a mostly-flat sled, with basically no protection other than a helmet. Luge sleds are a bit longer, and the athlete lays on their back on the sled, and goes down the track feet first, where Skeleton lays face-down on the sled, and goes down head first. Nordic combined is Cross Country and Ski jumping with nordic skis (the heel is not connected to the ski (as opposed to alpine skis, where the heel locks in)).
So why are downhill, slalom, and giant slalom lumped together under "Alpine", but ski jumping, biathalon, cross-country listed separately and not lumped together under "Nordic"?
Probably because ski jumping and cross-country skiing are quuuiiiiteeee a bit different (and no ski jumper also competes in cross-country and vice versa; that's why there's a separate sport, called nordic combined). Meanwhile, all the alpine skiing categories are much more similar than the nordic skiing categories (you ski down a slope while maneuvering the gates). That's why a whole bunch of skier compete in more than one category (usually the "technical" skiers do slalom and GS, while the "speed" skiers do super-GS and downhill, but there have been many skiers in the past who competed in ALL of the 4 major categories).
Sorry, but ski jumping and cross-country skiing are way too different to lump together under the "nordic skiing" umbrella term.
maybe i am stupid, but why are there like 7 variations of skiing listed but the variations of figure skating are all under one umbrella? theres 4 very different figure skating events: ice dance, pairs, men's singles, and lady's singles.
You are totally correct that all of them could be listed, because they are different kind of figure skating. But all of them have same kind of logic: they are artistic and valued by judges. On the other hand different kinds of "skiing" have very different kind of logic, who is better and what causes the movement of an athlete.
In alpine skiing the force of movement comes from skiing downhill, but in cross-country the main force is made by skier. Freestyle skiing is nearer alpine skiing, but it has artistic elements and alpine skiing has not, because all that matters is how fast time you get. So, alpine skiing is more like speed skating and freestyle skiing is more like figure skating: the other pair has just time element and the second pair has judges evaluating performance and giving points.
Here you would have a quiz with all the events. That includes what you were talking about.
It is sometimes hard to make the difference between sport and event. An athlete can do different events but almost always one sport. For example, an alpine skier would compete in Downhill and Slalom, but not in Slopestyle, which is freestyle skiing.
The most notable exception is Ester Ledecka, who won the gold medal in Alpine Skiing (Super G) and in Snowboarding (Slalom) in 2018
Skiing should count for "freestyle skiing". That's literally the definition of someone going skiing. They aren't doing anything in particular, just going down the slope.

(What the heck is biathlon?)
