Read the passage carefully and answer the questions that follow in complete sentences.
The sun is an enormous star which gives us the light and heat we need to grow food and keep warm. It was worshipped as the most powerful god by the ancient Egyptians.
The sun is made up of gases, mostly hydrogen and helium. It is powered by a natural process called nuclear fusion. Nuclear fusion takes place in the centre or core of the sun, where temperatures are around 15 million degrees Celsius.
All weather is driven by the sun . It takes place in the atmosphere, the layer of air around the earth. The temperature of a place depends on how the earth is titled towards the sun, where the earth is as it revolves around the sun, and the position of the earth as it rotates every twenty-four hours.
The sun’s rays are strongest around the equator. There, the sun is directly overhead.
Hence, places along the equator are very hot. On the other hand, at the North and South Poles, the same amount of the sun’s rays is spread over a larger area of the earth’s surface. The rays also have to slant through a greater amount of atmosphere, which soaks up and spreads the heat. That is why it is always very cold at the Poles.
