My sketches (Assignment 1)

Final Work (Assignment 1)

Description
I made this symbol to show the effects of Greenhouse gases and what happened in the near future, if we do not care about this important and dangerous problem. So, I designed a cloud which is dark black and gray as a greenhouse gases and also a thermometer to represent the bad effect of my subject, the red color in the middle represent raise of the temperature of earth and the flame shows a terrible result of this concern.

Finally,I used color from window menu to choose a good color for the flame and also I choose 9pt for the stroke weight to show the flame more real.

Next,I used pen tool to make flame.

after that,I choose color from window menu again to find a good color for it.

Third,I used rectangle and ellipse tools again to make inside of thermometer and I expand them together with add to shape area from pathfinder.Moreover,I used star tool to make triangle for the top of the thermometer,also I used scissors tool to show the break of the top of the thermometer.

Second,I choose color from window menu and I put color like this that you can see now.

First,I used rectangle toll to make thermometer but instead of bottom of thermometer I used ellipse toll to make a cloud.Then,I pressed on align and used pathfinder to combine thermometer with a cloud.So,I clicked on add to shape area to expand them.

Greenhouse gases are the gases present in the earth's atmosphere which reduce the loss of heat into space and therefore contribute to global temperatures through the greenhouse effect. Greenhouse gases are essential to maintaining the temperature of the Earth; without them the planet would be so cold as to be uninhabitable. However, an excess of greenhouse gases can raise the temperature of a planet to lethal levels, as on Venus where the 90 bar partial pressure of carbon dioxide (CO2) contributes to a surface temperature of about 467 °C (872 °F). Greenhouse gases are produced by many natural and industrial processes, which currently result in CO2 levels of 380 ppmv in the atmosphere. Based on ice-core samples and records (see graphs) current levels of CO2 are approximately 100 ppmv higher than during immediately pre-industrial times, when direct human influence was negligible.
