Solved Unseen Passage Class 10
Living on the earth is rather like being at the bottom of sea hundreds of miles deep. Without atmosphere, there would be no people or animals, birds or fishes, tress or plants. There would be no weather, winds or rain. And there would be no blue sky, no rosy sunsets or dawns. Fire would be impossible without air, for burning is the union of oxygen with whatever is burned. Nor would there be any noise, which is the vibration of air - waves against our eardrums.
By day, the atmosphere serves as a great sunshade. It protects the earth from the full force of the sun by absorbing most of its harming radiation. But for the atmosphere, the daytime temperature would rise to 230 degrees Fahrenheit, hotter than boiling water. By night, the air acts like a giant greenhouse. It imprisons the heat collected during the day and prevents it from spreading into space.
Word-meanings :
- atmosphere - वायुमंडल
- vibration - कम्पन
- protects - रक्षा करता है
- radiation - विकिरण
- giant - विशालकाय।
