| The Earth on fire |
This hellish Earth of the future will
be devoid of water, meaning it will likely
support no life forms. While its surface
will burn with an unbearable heat,
its once fiery core will be frozen solid.
Cold outer core
Our planet’s outer core will freeze in 2.3 billion
years, so without this liquid surrounding, our
planet’s magnetic field will shut down. This
field could then let go of the ozone
that protects us from the Sun’s harmful rays.
Frozen core
Currently the Earth’s inner core is growing
at a rate of around one millimetre (0.04 inches)
per year, but this might not be the case some 2.3
billion years from now.
Burning surface
In 2.8 billion years Earth’s surface will
reach unbearably hot temperatures with
everywhere averaging 147 degrees Celsius (297
degrees Fahrenheit).
