Light and heat energy from the
Sun
Most of this is reflected back
into Space
Only a small amount is absorbed and warms the Earth’s
surface
Healthy Planet
What is Global Warming?
Earth’s Atmosphere
![Page 6: 6.2 Global warming impacts What’s this got to do with global warming?](https://reader035.vdocuments.us/reader035/viewer/2022062720/56649f155503460f94c29bbe/html5/thumbnails/6.jpg)
Not so healthy planet
Greenhouse Gases
Only a small amount is reflected back
into Space
A lot more is trapped by the
gases and absorbed. The
temperature of the Earth’s surface
increases.

6.2 Global warming causes
Some greenhouse gases...
Water vapour (H2O) from...
...evaporating oceans and lakes, and smaller amounts from burning gas and oil.
