«greenhouse» in the English dictionary: everyday — its meanings, how the lessons use it, and examples, each with its tree on Mova.

## Everyday

1. A greenhouse is a building made mostly of glass or clear plastic where plants are grown because it stays warm inside. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/G/greenhouse/#m1)
2. The greenhouse effect is the way some gases in the air trap the sun's heat and keep the Earth warm. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/G/greenhouse/#m2)
3. Greenhouse gases, like carbon dioxide and methane, trap heat; more of them makes the planet warmer. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/G/greenhouse/#m3)

### In the lessons

In science lessons a greenhouse shows how glass traps heat; this is used to explain the greenhouse effect and climate change. In everyday life gardeners grow tomatoes and seedlings in greenhouses. Phrases: greenhouse effect, greenhouse gases, greenhouse emissions.

### Note

Countable: a greenhouse, greenhouses. Not a green-coloured house! Myth: the greenhouse effect itself is natural and needed for life; the problem is too much of it, from extra greenhouse gases, warming the planet. British also say «glasshouse».
