Solar activity has a great impact on the earth. For example, the occurrence of flares will cause the earth's shortwave radio communications to be weakened or even interrupted. When the large sunspot group passes from the center of the sun, a "magnetic storm" often occurs on the earth, causing the earth's magnetic needle to swing left and right, turbulent, and the compass losing its pointing function. Interestingly, the beautiful auroras at the Earth's North and South Poles often occur at the same time as magnetic storms. Solar activity also has a major impact on the Earth's climate, raising or lowering air pressure and increasing or decreasing rainfall. Meteorologists are very concerned about solar activity because it has a lot to do with weather forecasts.
In short, the sun is closely related to human life on earth. Fundamentally, most of the energy on Earth comes from the sun. The grains, vegetables, and fruits we eat grow by sunlight; the coal, natural gas, and oil we burn were formed by organisms that grew under sunlight hundreds of millions of years ago and were buried underground due to changes in the earth's crust; herbivores eat plants. Carnivores mostly make a living by eating herbivores. It can be seen that the energy of animals and plants, including humans, ultimately comes from the sun. Now many scientists are working hard to study how to use solar energy more directly, because solar energy is available everywhere, is inexhaustible, is cheap and high quality, and does not pollute the environment. Nowadays, there are many kinds of solar equipment, including solar cookers, solar water heaters, solar refrigerators, solar water pumps, solar medical equipment, solar air conditioning units and so on. Particularly worth mentioning are solar cells. It is widely used on space vehicles such as artificial satellites, so that humans have energy guarantee in space exploration. The sun brings warmth and hope to mankind, and mankind will always admire and praise the sun.
