No-oxy­gen Earth

A few sec­onds without oxy­gen could spell the end of life as we know it

How It Works - - SCIENCE -

Hy­dro­gen oceans

If all the oxy­gen dis­ap­peared from the water mol­e­cules in Earth’s oceans we’d end up with seas of ex­plo­sive hy­dro­gen gas.

Vi­o­lent wind

If 21 per cent of the at­mos­phere sud­denly dis­ap­peared, the pres­sure change would trig­ger swirling winds.

No sun-shield

The ozone layer (which is made from oxy­gen) would dis­ap­pear, show­er­ing Earth in in­tense ul­tra­vi­o­let ra­di­a­tion.

Boil­ing away

Hy­dro­gen is the small­est, light­est el­e­ment, so Earth’s oceans would boil away into space.

Crum­bling ter­rain

If oxy­gen sud­denly dis­ap­peared from the rocks the ground would be­gin to crum­ble.

Rain­ing ash

Car­bon from car­bon diox­ide would drop out of the air, leav­ing an at­mos­phere of in­ert ni­tro­gen.
