Rank in order of importance/significance
what is the name given for a cooling period in earths history
glacial period
what is meant by the term inner-glacial?
period of global warming
True or false? There is correlation (link) between CO2 atmospheric concentration & global temperature
true
Identify 4 pieces of evidence for past climate change
glacial retreat, ice core analysis, tree ring analysis, sea level rise
explain how scientists use ice cores to tell us about pass climates
scientists study the thickness of the rings in order to tell us what the climate was like - the thicker the ring, the warmer and wetter the climate was
explain how scientists have use ice cores to tell us about past climates
scientists use advanced technology to analyse the gases trapped in the ice cores layers the more carbon dioxide present, the warmer the climate was
which piece of evidence for past climate change is most reliable
ice cores analysis due to the technology they use to analyse the ice cores
give 3 examples of fossil fuels
coal, oil and natural gases
what are greenhouse gases
potentially harmful gases that trap heat in the earths atmosphere carbon dioxide and methane
what is the enhanced greenhouse effect
human activities increasing the amount gases being released in the atmosphere this is trapping extra heat, causes the earths temperature to rise
identify x3 human activities that are enhancing the greenhouse effect
transport, deforestation, industry, energy
