This term in class we started to look at Explanations in Writing. First we learnt how to write them, then we had a go at writing our own. All the members of our class wrote about the GreenHouse Effect- known as greenhouse gases that are in our solar system. Here is my piece of work and a diagram to show what I learnt…

 

Green-House Effect
The greenhouse effect is when sun rays are sometimes are absorbed, warming up the earth, but some rays can bounce back out into space. Greenhouse gases are really good for things on Earth. If we didn’t have greenhouse gases it would be freezing on Earth as the temperature would drop to about -18 degrees.

For the greenhouse gases to work we need the sun to give solar radiation and rays so the Earth will stay warm, the greenhouse gases, carbon dioxide, nitrous oxide and methane also keep the Earth warm.

For the greenhouse effect to work the sun needs to produce solar radiation and rays to hit the earth, while the rays try to get to the Earth it bumps into tiny little particles called carbon dioxide, nitrous oxide and methane which warms up the rays and radiation. Some of the solar radiation and rays will hit the Earth while others will bounce back into space.

The greenhouse effect acts like a big blanket on the Earth heating and re-heating the world. Things that effect the greenhouse gases can be cars – pollution, processed things including plastics, rubbers and electricity, people use electricity to warm up the Earth not the sun.

I believe that the greenhouse effect is a good thing that heats and re-heats the Earth. I think that the greenhouse gases help make and keep the Earth warm. I also believe that humans should do something I reduce greenhouse gases

I hope you enjoyed reading my piece of writing!
