What would happen to the earth if the atmosphere disappeared?

उत्तर
If the atmosphere disappeared, life on Earth would not be possible. The atmosphere provides air for breathing and protects us from the Sun’s harmful rays. Without it, people, animals, and plants would not survive. The Earth would become very hot during the day and extremely cold at night, because the atmosphere helps in keeping the temperature balanced. There would be no clouds, no wind, and no rain. Also, we would not be able to hear any sound because sound needs air to travel. Water would also start to boil and disappear because of no air pressure. The sky would look black even in daytime, and meteors would fall directly on Earth without burning up. So, the atmosphere is very important for life and protecting our planet.
