Doomsday to the Core
Turns out the Earth could become cold hearted!
The Center of the Earth
As you may know, our planet is filled with super hot fluid known as magma. Even deeper in the Earth's core, There is a large body of liquid made up of melted iron and nickel. Without it, we would have no land to live on! The magma constantly replenishes the land: it boils up in the Atlantic ocean, freezes and thus constantly adds rocks and soil to our world. Every mountain you see, every piece of stone you pick up: it was all one liquid magma! Very slowly, the Earth is cooling down from the outside in, much like an oven dish placed in the fridge. The Earth is freezing. In the end, the Earth's core will no longer be liquid, but solid. Our planet's restless bowels will calm down -- forever. The first thing you should notice is less volcanoes, and less earthquakes. Slowly, wind and rain will begin to erode the Earth away. Very gradually, mountains will shrink and wash away in the rain. In the end, there will be no land left. No continents, rocks, islands, not even a sand bank. All of the land on our planets will cease to exist. Our planet will just become an entire body of water.
