Question 18 options:
|
1)
|
The ozone hole has allowed extra ultraviolet radiation to be absorbed in the Earth's atmosphere |
|
2)
|
Greenhouse gases, put into the atmosphere by human activities, affect Earth's emission of infrared radiation |
|
3)
|
The Earth's climate is still recovering from the last ice age |
|
4)
|
The Earth system is too large to achieve radiative equilibrium |
Earth's energy budget is the balance between the radiant energy to the Earth from the sun and the energy that flows back to the sun.
For Earth as a black body the total energy received should be equal to the total energy radiated.
Taking albedo into consideration, calculations show the temperature of the Earth should be -18 °C, but there is something which is contributing to the surface temperature of the Earth that is 30 °C.
