Question

how does atmosphere protect us from meteorite hit

Answer 1

Without an atmosphere, objects like meteors would be free to crash into the surface of our planet. Fortunately, our atmosphere is able to protect us from such potential disasters by actually burning up such objects before they have had a chance to hit the surface of Earth. The reason space debris burns up in our atmosphere is because such objects fly towards Earth at great speeds. As these objects pass through the atmosphere, atmospheric gasses compress very quickly. This generates great amounts of heat, burning the objects up as they fly through. During this pass through the atmosphere, temperatures can reach as high as 3,000 degrees Fahrenheit (1650 degrees Celsius)!....
