How Do Greenhouses Work?
• Greenhouses are glass buildings for growing plants.
They protect plants and keep them warm even in winter.
• Sunlight goes through the glass and makes the air in the
greenhouse warm.
• However, heat cannot escape, so the greenhouse gets
warmer and warmer.
The Earth Is Like a Greenhouse
The problem now is that the earth is
getting warmer and warmer (global
• Sunlight goes through the warming) because there is too much
earth’s atmosphere and carbon dioxide in the atmosphere. This
makes it warm.
