BEGINNING OF LIFE ON EARTH
Beginning of Life on Earth Day 1: Formation of Earth Study Material: Formation of the Solar System: Billions of years ago, our solar system began to form from a giant cloud of gas and dust called a nebula. Over time, gravity caused this cloud to collapse, forming a spinning disk. In the center, the Sun formed, and around it, smaller clumps of matter began to gather, eventually forming planets, including Earth. Early Earth Conditions: When Earth first formed, it was a hot and violent place. Molten rock covered its surface, and frequent volcanic eruptions released gases into the atmosphere. The atmosphere likely contained gases such as water vapor, carbon dioxide, methane, and ammonia. Formation of Oceans: As Earth cooled down over millions of years, water vapor in the atmosphere condensed into clouds and fell back to the surface as rain. This rain filled the low-lying areas of Earth's surface, forming the first oceans and seas. These oceans were essential for the development of...
