which would have a smoother shape, a young mountain chain or an old mountain chain? why?

Older, more erosion and less break off on cliffs etc.

gravity.\n\nany shape of mass that is not spherical is gravitationally unstable

I'm sorry, not enough information. You could go to the Yahoo search engine under images and enter hill or mountain image. You might find something or go back to the conference organizers for the name.

Well, maybe a little, but if they have it, it is really old and altered.  Below is a link to the geologic map.

You are misunderstanding a few different concepts here.  That is a pretty good definition of uniformitarianism...but it's important to understand that mountains are also building as they are eroding. An example of this is the Himalaya; they are sill rising about 3 inches every decade.  Hardly any erosion takes place on the higher peaks - too cold/covered in snow and ice.\n\nAlso, mountains build up in some areas, some areas erode, and many areas (of land) remain little changed (that's where you get your (relatively) young bones.  Many areas of land are also deposition areas that add material on top of old material (that's why you dig up bones and fossils).\n\nCatastrophism is now viewed as a very legitimate factor. Think of asteroid impacts, volcanoes, or the massive flooding caused by the end of the ice ages (do you think that little Colorado River carved the Grand Canyon?).\n\nSo we rectify both by seeing the proper blending of the two - a largely uniform Earth that is infrequently influenced by catastrophes.

A, because it's the division between two tectonic plates. the plates move apart and magma from inside the earth comes up and piles up in the form of mountains.

because on the mountains the air is more thin...duhh

The Appalachians were & are also some of the oldest orogenies.\n\nTwo others are the Alps in Europe & the Rockys in Western US & Canada

the older is so much better

The best way to observe this will be from abutments in layers, one layer within the soil zone will be directly on top of and/or cut off layers below.\n\nThe induvidual features each have their own special features.  Debris flows are matrix-supported with large chuncks on top toward the middle of the deposit.  slumps will have extensional features at the top (cracks), and compressional features at the base (folds).  They are also associated with springs along the plane of weakness.  Slides will be normally graded (big on bottom, small on top).\n\nLahars are completely different, and have volcanic origins.

cause things get older not younger.

Two ideas: 1. Eroded (continental glaciers form deep valleys)\n                 2. Depressed (see link on isostacy)\n\nMaybe look in your text book.

Cartilage is much more flexible and pliable as compared to bone.In some cases it may also appear translucent when held up to a strong light source.As the others have said,cartilage wont last as long as bone.so if the skeleton is really old then it probably is bone.On the other hand if it is new then look for flexibility and translucency.

a mountain wind would be colder, drier, and less fragrant\n\nof course it depends on what you call a mountain, some people use that name for ridiculous little molehills just cuz they're the only thing around, in that case not much.

I would have liked the old look better.

Cliff or steep rock face, on the coast or inland

That has absolutely no sense at all...\n\nHow do you think the Rocky Mountains and the Andes were formed but by millions of years of earthquakes????\n\nWas it hot then?\n\nOf course not! Some of them occured during the glacial era. No SUVs then!\n\nStop listening to stupid people such as Greenpiss!!!
