The Core of Our Problems
Time Frame: ~50-90 Billion years
The core of the planet is filled with magma (liquid metals like iron and nickle)
The core is slowly cooling down from the outside in
First thing you would notice is less earthquakes and volcano eruptions
No new land will be replenished from volcanoes and the earth will erode away from rain and wind
No more land left only a water planet
The inner core will begin to freeze
This will destroy the earths magnetic field
Our earth will be bombarded with radiation and our atmosphere will slowly vanish
With no atmosphere the water on earth will slowly evaporate and we will be left with a cold dry planet
