Q: what do you know about surface of the earth?
| Option | Answer | Is Correct |
|---|---|---|
| 1 | It is a fact that the surface of the earth has throughout its history been subject to changes which are taking place even today. in the beginning, when the earth was extremely hot, these changes were sudden and violent. But now when the surface has gradually cooled, these changes arc so slow and gradual that they are scarcely perceptible. The isles of Japan are slowly rising, while the coast of South Sweden and East England are sinking. During the last one thousand years some inland towns in the east of England have become ports. There was a time when an ocean rolled where the Himalayas erect their lofty heads now, and Australia was at one time joined to Asia. But how are these changes brought about? There are forces such as contraction of the earth, volcanic action, earthquakes. which have their origin in the interior of the earth and bring about changes on the surface. And there are forces, such as water, air, winds, temperature, etc. |
