All Scottish territory was covered by ice during the Pleistocene ice ages, which has a significant impact on the landscape.
From a geological point of view, Scotland is subdivided into three areas: the Highlands and islands are located to the northwest of the failure of the Highlands, stretching from the Isle of Arran to Stonehaven.
This part of Scotland is composed primarily of old rocks from the Precambrian and Cambrian periods, which were high during the subsequent Caledonian orogeny.
This base is connected by multiple rock igneous intrusions of more recent times, whose relics have formed mountains as the Cairngorms or Cuillins on Skye.
A significant exception to the above are the strata of sandstone known as Old Red Sandstone, which have found fossils, found mainly around Fjord Moray.
The Highlands are generally mountainous and are divided by the Great Glen or "Great Valley."
The highest elevations of the British Isles can be found here, including Ben Nevis, the highest peak, with an elevation of 1,344 meters.
Scotland comprises more than 790 islands divided into four main groups: Shetland, Orkney and Hebrides, which in turn are divided into Hebrides Interior and Foreign Hebrides.
Moreover, in this area, there are several sources of fresh water, including the Loch Ness or Lake Lomond.
