The correct name of the example is iron(III) oxide. Example #4: name this compound: SnO. 1  First symbol is Sn, so the first part of the name is tin. 2  The Roman numeral is II, because one oxygen = -2, so the one tin equals +2. 3  Second element is oxygen (from the symbol O), so the name is ox + ide = oxide.

The Canadian Shield is amongst the oldest on earth, with regions dating 2.5 - 3.5 billion years. The multitude of rivers and lakes in the entire region is caused by the watersheds of the area being so young and in a state of sorting themselves out with the added effect of post-glacial rebound.he lowlands of the Canadian Shield have a very dense soil that is not suitable for forestation, but it also contains many marshes and bogs. The rest of the region has coarse soil that does not retain moisture well and is frozen with permafrost year round. Forests are not as dense in the north.
