Top 10 Amazing Earth Facts

[bimo]

well known and well traveled as our planet is, there are still new things being discovered every day. In fact, most of our oceans haven’t even been explored yet which is why when new depths are located; they often come with hundreds of new species. Rain forests offer up new animals and plants as often as we can explore them. The Earth is constantly changing, shifting, and exposing new secrets for humans to marvel at. It took many years and many great minds to solve the problem of getting through Earth’s atmosphere into the wide expanse of space beyond. Here are ten amazing facts about our home that you may not be aware of.

Many layers of atmosphere coat our planet including the mesosphere, ionosphere, exosphere, and the thermosphere, but it’s the troposphere, closest to the planet itself, that supports our lives and is, in fact, the thinnest at only about 10 miles high.


9. Deserts

Believe it or not, most of the Earth’s deserts are not composed entirely of sand. Much, about 85% of them, are rocks and gravel. The largest, the Sahara, fills about 1/3 of Africa (and it is growing constantly) which would nearly fill the continental United States.

The deepest lake in the world is in the former USSR and it is Lake Baikal. It has a length of 400 miles, a width of roughly 30, but its depth is just over a mile: 5,371 feet down. It is deep enough, so is speculated, that all five of the next largest lakes: The Great Lakes could be emptied into it.
