Question

State three characteristics of Canadian shield.​

Answer 1

Explanation:

The Canadian Shield's most notable physical features are thousands of small lakes, thin layers of soil and rolling hills. Lakes are largely the result of glacial erosion during the last ice age.

Shields themselves can be very complex: they consist of vast areas of granitic or granodioritic gneisses, usually of tonalitic composition, and they also contain belts of sedimentary rocks, often surrounded by low-grade volcano-sedimentary sequences, or greenstone belts.
