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.
Saturnâs average distance from the Sun is 1,400,000,000 km. The average orbital speed of Saturn is 9.69 km/s. It takes the earth 365 days to orbit the sun, Saturn takes 10,759 Earth days (or about 29Â½ years), to revolve around the sun; a year on Saturn is equivalent to 29.5 Earth years. Saturn has an elliptical orbit and is inclined at 2.48Â°. The reason for Saturn not having a constant distance is it has an eccentricity of 0.056. This causes the distance between Saturn and the Sun to vary by 155,000,000 km between aphelion and perihelion. The aphelion is the most distant part of the planet along its orbital planet while the perihelion is the closest. Parts and features of Saturn that are visible to earth have different rates of rotation.
