The diagram shows two processes, X and Y, together with their effect, Z, in raising global warming. Which row identifies X, Y and Z?
- AX: absorption of thermal energy by greenhouse gases; Y: emission of thermal energy to the Earth; Z: reduced thermal energy loss to space
- BX: emission of thermal energy by greenhouse gases; Y: emission of thermal energy to space; Z: reduced thermal energy loss to space
- CX: absorption of thermal energy by greenhouse gases; Y: emission of thermal energy to the Earth; Z: increased thermal energy loss to space
- DX: emission of thermal energy by greenhouse gases; Y: emission of thermal energy to space; Z: increased thermal energy loss to space
