Answer 1

Answer:

• (1). The Solar System was formed from a rotating cloud of gas and dust which spun around a newly forming star, our Sun, at its center. ... The gravity of the Sun keeps the planets in their orbits. They stay in their orbits because there is no other force in the Solar System which can stop them.

• (2). So, when our eyes see light, our brain gets signals that make us feel awake. But when its dark, the signals make us feel tired. This is part of a process called the circadian rhythm. This works like a natural clock in our body.
