Answer to Question 1

B

Answer to Question 2

All bodies in the solar system formed from an enormous cloud composed mostly of hydrogen and helium, with only a small percentage of heaver elements. When this huge accumulation of gas and dust revolved around its center, it began to contract under its own gravity, becoming hotter and denser, eventually forming the Sun. As the matter that formed the Sun contracted, small amounts of it were left behind in swirling eddies. The material in these eddies was the beginning of the protoplanets and their orbiting satellites, which later consolidated into the present planets and their moons.
