Geography of Scotland example at Aberdeen. Much of the Scottish coastline consists of a machair formation, a dune pasture land formed as sea levels subsided. The east coast has several significant estuaries and other nature reserves including the Ythan Estuary and Fowlsheugh, both of which have been designated as Important Bird Areas. Firths of Scotland include the Solway Firth, Firth of Clyde, and Firth of Lorne on the west coast, and the Cromarty Firth, Moray Firth, Firth of Tay, and Firth of Forth on the east coast. The Pentland Firth is not an inlet, but the strait that separates the Orkney Isles from
Firth of Clyde m wide and is operated by Northwestern Shiprepairers Limited using the name Scott Lithgow, although unrelated to the famous Port Glasgow Scott Lithgow shipbuilding company. The Firth of Clyde has one of the deepest sea entrance channels in northern Europe, which can accommodate the largest Capesize vessels afloat, and as such the Clyde is one of the UK's leading ports, handling some 7.5 million tonnes of cargo each year. Hunterston Terminal was constructed to bring in bulk ore, but now mainly deals with coal imports. Supertankers up to 324,000 tonnes travel up the firth to deliver crude oil to Finnart
