How was the earth’s crust formed? |
|
Answer» The Earth remained in the molten state for many million years and then began to cool. The volcanic activity got reduced considerably. The gradual cooling of the Earth made the outer side to become solid rock, which is called Earth’s Crust. Further cooling made the Earth’s crust to contract resulting in the formation of mountains and valleys. They are like folds and wrinkles appearing on an apple which is left to dry for a few days. The gases released by Volcanoes created the primordial atmosphere. The crust was still hot and water was in the form of steam. Further cooling condensed the steam to form clouds and then rains began to pour in torrents. This continuous downpour formed lakes, rivers, oceans and seas. The rains and winds eroded the valleys and mountains. The erosion formed rocks to break and form tiny particles of sand and mud. The continuous erosion formed soil and the ocean floor. |
