uplift???
Alright, so I attempted a hiking trip in Uppsala recently. The plan was to follow the river that cuts through town upstream, which turned out to be largely impossible, but one of the shots I got was this:
Update Your Browser | Facebook
It's a public link, so you can open it even if you're not in facebook.
Anyhow, that's the river that eventually cuts through town about 15km downstream.
What I want to know, is whether uplifting is responsible for any of the bank height. Sweden rises on average 1yd/century (haven't found any figures for Uppsala specifically). The river bank is about 9-12 feet high. I'd say that this is the normal water flow, as the owners have placed an electrical fence splitting the river bed down the middle (not entirely sure I was allowed to hike there ). On both sides it's either farmland or pasture, so I'm not sure if the banks have been built up, leveled out, or whatnot.
Opinions?
oh, and to the mods: if this isn't the right forum, feel free to shunt this off to where ever it belongs.

Re: uplift???
Yes, and the grand canyon doesn't have a lot of vegetation. Yet it is very old (6 million years or so).
I don't see what vegetation has to do with age.
In fact, I'm not really sure what age has to do with the photo. The only relevant information is that sweden was under an ice sheet 10,000 years ago, and Uppsala has been settled since before christ.
So, anyone who might actually know something about geology have an opinion?
oh, and CS:if I was worried about anonymity, I certainly wouldn't have my current username or photo.

Re: Spiral Galaxy?
A disc galaxy is a spiral galaxy.
There are four types of basic galaxies.
Elliptical (anywhere from a giant sphere to an american football (or perhaps the ball in rugby, if that's more familiar).
Spiral (rotating disc of stars with a central bulge)
Irregular (well, the name kind of says it).
and Dwarf (which are far, far smaller, about 1/100 of the Milky Way, and they are also classed by the above three cats)
We know the Milky way is a spiral because of observations and mass distribution. We've also managed to figure out things like our orbital velocity. Technically, we're a barred spiral galaxy. The latest news is that we're almost 50% bigger than we thought, based on a new orbital velocity of about 914,000km/h.
But yeah, figuring out what the home looks like when you can only see from inside one room is a touch difficult.
Check out these two wikis:
Milky Way - Wikipedia
Galaxy - Wikipedia

Re: uplift???
I'll see if I can dig up the soil types around here. Unfortunately I no longer have my grandfather to ask, as he was a geologist/civil engineer with a Swedish firm (not sure if he actually worked for the swedish gov't, though). On the plus side, Uppsala is known for its sciences, so I'm sure there's someone/thing with relevant info.
Thanks.
