<p ><b class="first" >T</b>hat it teems with life makes Earth a precious oddity
|
|
among the planets-although just how off, scientists cannot say. Certainly the
|
|
conditions that made life possible were sensitive to the planet's surface
|
|
temperature and therefore to its distance from the sun.</p>
|
|
|
|
<p >Abundant liquid water was critical to the planet's evolution. This water
|
|
moderated temperatures, eroded rocks, dissolved minerals and supported complex
|
|
chemical reactions, some of which yielded single-celled life close to four
|
|
billion years ago. Macroscopic animals started proliferating only around 600
|
|
million years ago, eons after photosynthesis enriched the atmosphere with oxygen.</p>

|
<p >Earth's large moon probably formed from the debris after a collision between
|
|
early Earth and another huge body. Because the moon and sun appear the same size
|
|
from Earth, or planet is the only one to witness the beauty of the sun's corona
|
|
during a total eclipse.</p>
