The earth's early atmosphere
Loss of sea ice
Increasing sea levels
Animals (birds) change to migration
Crops are able to grow in places they couldn't before
Energy transferred from the sun on to the earth's surface
The earth emits energy
However, some energy is absorbed by greenhouse gases and transferred back to earth.
Some emitted energy is transferred into space
Most of the energy is absorbed, increasing the earth's temperature
Some energy is reflected into space
Methane is released as well as CO2 when burning fossil fuels but is also released when cattle ranching.
When fossil fuels burn, they release CO2, helping the greenhouse effect.

The change in the atmosphere
Levels of oxygen increased as the rate of photosynthesis increased which also reduced amounts of Carbon dioxide
The earth's temperature decreased and the water vapour cooled and condensed to form oceans.
Carbon dioxide decreased as it dissolved in oceans.
Gases in the early atmosphere are thought to have come from
