The green house effect & climate change
A greenhouse is a house made of glass that people use to grow different
plants. It can trap heat inside from the Sun and this means that the inside
of the greenhouse is always warm – even in winter.
The Greenhouse Effect happens naturally and it is something we need to
maintain life on Earth. Certain gasses (methane, water vapor, carbon
dioxide, nitro us oxide and ozone) in the atmosphere act like a green house
by allowing many rays from the sun enter the atmosphere but only letting
some escape. This allows the Earth to remain at a constant temperature
that we can survive at.
