Life On The Earth



Life On The Earth:  Evidence suggests that life on Earth has existed for at least 3.5 billion years, with the oldest physical traces of life dating back 3.7 billion years] however, so and the chemistry leading to life may have begun shortly after the Big Bang, 13.8 billion years ago, during an epoch when the universe was only 10–17 million years old.

It will result in fatal arrhythmias or heart attacks.2 While the results of stress in sheep are well documented,3 there are fewer studies on wild animals, and therefore the severity and range of stressors that afflict wild animals have most likely been underestimated by research, apart from the results of captivity on wild animals.

The Dynamic of the Earth's surface is virtually the fundament of all human uses of the landscape. However, human influence isn't restricted to the surface; rather there's abundant interaction with the near-surface materials, as an example, in terms of nutrients and water delivered from there to crops and trees or of pollution introduced into the underwater. For basic analysis, surface and underwater square measure of equal interest as a result of they create up the foremost interface for all Earth-surface processes. This importance of the near-surface materials—with slope deposits being among the foremost widespread of those materials—has been acknowledged for decades, however, this has gained abundant progress through the “Earth's crucial zone” idea. this idea makes attempt to desegregate all ecological interdependencies from the highest of the cover layer all the {way down to} and as well as the active H2O zone in an exceedingly holistic way.
