- 4.5 billion years ago
- The Earth was a very
volcanic and violent
place
- Atmosphere mainly
consisted of carbon
dioxide and water vapour
- This was because
volcanoes kept
releasing these
- Later, temperatures
began to cool and oceans
were formed and firsts
signs of life existed, the
rest is a mystery
- Greenhouse gas effect
- It is when heat enters
the atmosphere and
stays trapped in
greenhouse gases
and therefore warm
up the earth
- Natural greenhouse gases
- Water vapour, carbon
dioxide,nitrous oxide,
methane and ozone
are all types of
greenhouse gases
- Man-made greenhouse gases
- These are constantly increasing
in the atmosphere due to
human activities such as
burning fossil fuels
- Acid Rain
- Rain that is acidic
(has a pH below 7)
- How's it made?
- 1. Acid gases enter
the atmosphere
- 2. Acid gases
dissolve
moisture in the
air
- 3. Clouds cool and
produce Acid rain
