The UK, Ireland, Norway, North and South America, New Zealand etc. all have most of their mountains and glacial "jagged "coastline on their west.  Eastern coastlines seem to be generally much "smoother" and generally less hilly.

What is the reason for this and are there any exceptions?

It was found in the Swiss Alps. It is quite heavy, maybe 500g.

We were at altitude 2674m on a mountain ridge when we noticed that the pole with indication signs for the trails was vibrating. The same was with the digital camera and the hiking poles. We understood that there was electricity in the air. However, the happening was strange because though the sky was covered, it was snowing, and not heavily. Besides, there were no lightnings, but we could hear from time to time thunders. I was wondering if there was any chance of being struck and also, if possessing metal objects might increase the chances.

During a walk last Easter to the Summit of Mt Kosciuszko (Australia's highest mountain) I  was suprised to spot some fish swimming in a small pool approximately 200M from the top of the mountain. The pool appeared to be a small man-made drainage channel that drained under the walkway. My question is how did the possibly get there? The mountain is covered in freezing snow for most of the winter months (July - September) so I thought it unlikely that they woud survive. They cannot have existed there since day dot. Did someone put them there?

While walking in the Cairngorms, a path had muddy puddles one day, and was frozen the following day. Parts of the path were the mixture of ice, air and gravel pictured. The structures are noticeable, because they collapse when stood on. They are different to any normal frozen puddles, because they are not solid ice, nor are they a layer of ice with water or air beneath. The pictured piece measures about 65x65 mm.

The Himalayas are only 6m years old, therefore Everest is young in geological terms. Do we know of any "extinct" mountain ranges particularly ones that could be higher than Everest? What is the highest mountain that Earth could support and how would it be made? Limestone all the way to the top would presumably collapse under its own weight; granite would presumably sink back into the crust.
