Although we think we know quite a lot about the planet we live in, Earth actually has endless unknown features that people are continuing to find out. Human-beings have yet to explore all of Earth's waters and seas and there is a possibility that there could be more than 700,000 undiscovered species in this world. For a little sneak peak here is a list of interesting facts that you may not be aware of:
1. The Atmosphere
We all know that this earth is coated with numerous layers such as the mesosphere, ionosphere, exosphere, and the thermosphere. However, the layer that supports all lives, the one we live on is actually the thinnest layer; the troposphere.
2. Deserts
Would you be amazed if I told you that the deserts on earth are not mostly composed of only sand? About more than 85% of them are rock and gravel. Not to mention that the largest desert, the Sahara, takes over almost 1/3 of Africa (and it is continuously growing!), which is enough to fill the continent of the United States.
3. Salty Oceans
Oceans, as we know it, are where we can get natural salt. But the amount is so huge that if we were to evaporate all the water and spread the salt over all land on Earth, we would get a 500 foot layer coating everything.
4. Shaky Ground
The majority of the people nowadays, especially after countless destructive earthquake cases around the world, may think all of them as deadly and life-threatening. However, the Earth releases about 1 million of these every year, and almost all of them are never even registered.
Other than these brief pieces of information, there are numerous facts about the Earth that we may never even have imagined. Nowadays scientists find a continuously changing state of the Earth due to human abuse and wastes we dump on it. Let's just remember that without Earth, there is no other secure place for us humans to take shelter; let's make it a clean and safe place to live in ourselves.
