6 billion years old. However, the mountains, valleys(山谷), hills,rivers, deserts and forests we see today are much younger than that.For example, Mount Qomolangm a is about 60 million years old and the Amazon rainforest is only 10 million years old. The youngest se a in the world ...
It doubled to 2 billion in the early 1900s. During the past 110 years. We’ve added nearly 6 billion more people. Look at the map below and you will see how the world’s increasing population influences places in different parts of the world. border:solid black 1.0pt;padding:3.75pt ...
“first peoples” on this planet are kidding themselves, we know the planet is billions of years old, plenty of time for earlier civilizations to have flourished and died, with time erasing most of their existence, easily done in less than a billion of the 4 to 5 billion years we think ...

An asteroid some six miles (10 kilometers) wide or bigger smashed into Earth and created the Vredefort Crater, in present-day South Africa, some 2 billion years ago, long before even thedinosaursevolved. At the time, researchers estimate the impact crater was a whopping 112 to 186 miles (...
The geological record following the c. 2.3 billion years old Great Oxidation Event includes evidence for anomalously high burial of organic carbon and the emergence of widespread mountain building. Both carbon burial and orogeny occurred globally over the period 2.1 to 1.8 billion years ago. Prolific...
The best-studied history is that of the continental part of the earth’s crust, within which, about 1.5-1.6 billion years ago, the formation of the ancient (Precambrian) platforms that constitute the principal masses of the present continents was basically completed. These platforms are the Easte...
During the PaleoProterozoic 2.45 to 2.2 billion years ago, several glaciations may have produced Snowball Earths. These glacial cycles occurred during large environmental change when atmospheric oxygen was increasing, a supercontinent was assembled from numerous landmasses, and collisions between these land...
After atmospheric oxygen levels spiked 2.4 billion years ago, not much happened on Earth for another billion years. Earth was so staid that scientists call this stretch of time the "boring billion." Things were pretty quiet tectonically, too: The continents were stuck in a supercontinental traffi...
