The process

























This is my sketch when it is fully coloured.Below will be the process of making this symbol.

For the first layer i made the fire using the pencil tool for the outline.
Then i fill in the colour, for the outer layer i fill in the colour orange to represent the colour of the fire and for the second layer i fill in the colour blue that represents the sea.



















The next part of the process i did the house with cracks representing the greenhouse effect using the pencil tool.I place the greenhouse inside the fire and overlapping the map background because it is one of the effect that results in global warming.



















After that, i complete the map background by putting in the the details that is land using pencil tool for the outline and colour it in dark green following the actual colour in our map.I used the grey cloud and power symbol using pencil tool and paintbrush tool to represent climate change and frequent tropical storm that are happening because of the greenhouse effect


























This is the final look of my symbol which i named 'burning house' connecting the greenhouse effect with global warming.

These are all the elements that i use in my symbol:

GREENHOUSE EFFECT



My smaller topic on global warming would be the greenhouse effect. It refers to the circumstances where the short wavelengths of visible light from the sun pass through a transparent medium and are absorbed, but the longer wavelengths of the infrared re-radiation from the heated objects are unable to pass through that medium. The trapping of the long wavelength radiation leads to more heating and a higher resultant temperature. Besides the heating of an automobile by sunlight through the windshield and the namesake example of heating the greenhouse by sunlight passing through sealed, transparent windows, the greenhouse effect has been widely used to describe the trapping of excess heat by the rising concentration of carbon dioxide in the atmosphere. The carbon dioxide strongly absorbs infrared and does not allow as much of it to escape into space.

What is global warming?

The gradual increase of the temperature of the earth's lower atmosphere as a result of the increase in greenhouse gases since the Industrial Revolution.The temperature of the atmosphere near the earth's surface is warmed through a natural process called the greenhouse effect. Visible, shortwave light comes from the sun to the earth, passing unimpeded through a blanket of thermal, or greenhouse, gases composed largely of water vapor, carbon dioxide, methane, nitrous oxide, and ozone.

Infrared radiation reflects off the planet's surface toward space but does not easily pass through the thermal blanket. Some of it is trapped and reflected downward, keeping the planet at an average temperature suitable to life, about 60�F (16�C).
