- LOADS OF:-Carbon dioxide-Water Vapour-Nitrogen
- earth crust
- SMALLER AMOUNTS:-Methane-Ammonia
- in the first villain of years Earth's history
- Slide: 3
- When algae and green plants died they fell to the seabed and became buried in layers of sediments and over millions of years this sediment became compressed from sedimentary rock, oil and gas, which trapped the carbon, to stop it to getting back to the atmosphere.
- SEDIMENTARY ROCK
- Slide: 4
- In the first billion years of Earth's history the Earth was really dry and there was intense volcanic activity. Which produced:
- Carbon dioxide has declinedOxygen has built up
- INCREASED THE AMOUNT OF OXYGEN
- r
- ALGAE GREEN PLANTS
- PHOTOSYNTHESISCarbon dioxide + WATER --- GLUCOSE + Oxygen
- Slide: 5
- As the water vapour condensed into liquid water though it formed the oceans and this allowed lots of the CO2 from the atmosphere to dissolve in them where it could go on the from carbon precipitate and then finally become sediments in the seabed.
- Water VapourNitrogenCarbon dioxide
- This is the gases intense volcanic activity CREATES:
- During the first billion of years, the volcanic activity increased. This meant that lots of CO2 was created and other gases increased.
- Slide: 6
- OIL
- GAS
- SEABED
- CREATES:NITROGEN
- Lighting creates various gases but the main gas is nitrogen.
