Information Report about the Sun

The Sun

The sun is a large round ball that the planets travel around.

It is made out of many gases, chemicals and most importantly fire. The sun also lets off tiny explosions that create sunbeams and sunrays which gives us light and heat.

The sun formed first at the centre of the cloud. It became whole when gases and chemicals and dust started to grow.

The centre of the sun is called the core. The core is extremely hot. The heat sends tiny bits of matter called atoms crashing into each other. The crashing atoms set off atomic or nuclear reactions. All of the energy of the sun comes from these nuclear reactions in its core. It takes a long time for the energy from the core to reach the surface of the sun- about 170,000 years!!

The sun is very important to us. We play in the sunshine. We see daylight. The sun keeps us warm. Even ancient people knew the sun was very important. They thought the sun was a god. The ancient Greeks thought the sun god drove a chariot across the sky every day. The ancient Egyptians thought the sun god sailed a boat across the sky.

Heat from the sun warms up the ground. The warmth from the ground heats the air above. The sun warms us and gives everything life, so without the sun the universe would not exist!
