What does Earths Temperature depend on (4 Factors)?

1- the rate at which light & IR radiation is absorbed & emitted by earths surface and atmosphere 2- greenhouse gases ∴ activities like deforestation can increase temp. leading to climate change 3- When light & high frequency IR radiation is absorbed by Earth's surface, it's internal energy increases and it becomes hotter, some of this energy is transferred to the atmosphere by conduction and convection. 4- Low frequency radiation either bounces back into space or is absorbed by GHGases
