    sunlight through but traps the warm air from escaping. The warmed structures and plants inside the greenhouse re-radiate some of their thermal energy as glass is partly opaque causing convection due to energy trapped inside the glasshouse. The blanket layer of gases in particular carbon dioxide traps much heat and prevents it from escaping back into space as radiation. Mother Earth is gradually warmer as air is trapped as created by the ‘greenhouse effect’. The air that is warmed near the ground is prevented
