Greenhouse effect
The greenhouse effect is the natural process that warms the Earth’s surface. When suns energy reaches the Earth’s atmosphere, some of it is reflected back to the space and rest is absorbed and re-radiated. The absorbed energy warns the atmosphere and the surface of the Earth.
Process
1. Solar radiation reaches the Earth's atmosphere - some of this is reflected back into space.
2. The rest of the sun's energy is absorbed by the land and the oceans, heating the Earth.
3. Heat radiates from Earth towards space.
4. Some of this heat is trapped by greenhouse gases in the atmosphere, keeping the Earth warm enough to sustain life.
5. Human activities such as burning fossil fuels, agriculture and land clearing are increasing the amount of greenhouse gases released into the atmosphere.
6. This is trapping extra heat, and causing the Earth's temperature to rise.
How to control
1. Reduce, reuse, recycle
2. Use less heat & air conditioner
3. Replace your light bulbs
4. Drive less and drive smart
5. Buy energy – effluent product
6. Use less hot water
7. Save electricity
8. Plant a tree
