Total questions: 13
Worksheet time: 16mins
The current atmosphere is made up of around 78% (a) and 21% (b) . The remaining 1% is mostly (c) with only 0.04% being (d) .
Reorder the following
Volcanic eruptions released ammonia, carbon dioxide and water vapour
Water vapour condensed to form the oceans
Carbon dioxide dissolved into the oceans and reacted to form carbonates
Bacteria and plants evolved carrying out photosynthesis reducing carbon dioxide levels and increasing oxygen
Ammonia was broken down onto nitrogen and more nitrogen released over time
