Best Answer: The Canadian Shield is the oldest part of the North American continent. It was formed over 1 billion years ago probably through the collision of volcanic island archs that built on to each other.It is made of igneous rocks and highly metamorphosed rocks. I'm sure there are some sedimentary rocks as well.nswers. Best Answer: The Canadian Shield is the oldest part of the North American continent.

Saturn is one of the gassy planets and is huge compared to the size of Earth. Saturn has a diameter of 120,536km much bigger than Earth. Earth, however only has a diameter of â¦ 12,756km.
As a result, Jupiter's surface gravity (which is defined as the force of gravity at its cloud tops), is 24.79 m/s, or 2.528 g. Gravity on Saturn: Like Jupiter, Saturn is a huge gas giant that is significantly larger and more massive than Earth, but far less dense. In short, its mean radius is 58232Â±6 km (9.13 Earths), its mass is 5.6846Ã1026 kg (95.15 times as massive), and has a density of 0.687 g/cm3.
