The Big Bang The Creation
The Big Bang: * 15 billion years ago, universe created in explosion * 5 billion years ago, Earth was created * Beginning Earth was hot, molten spinning ball, as it became cooler, it became more and more solid * No water on surface, and atmosphere wasn’t formed * Evidence: 1. Universe still expanding 2. Space full of cosmic radiation 3. Hydrogen & HeliumMost common elements in universe 4. New starsborn, Old starsdie
The oceans: * 5 oceansAtlantic, Indian, Pacific and Southern * Developed when earths temp. dropped under 100°c * They are salty because minerals are dissolved in water * Oceans dissolve 40%-50% of carbon dioxide produced by burning fossil fuels * Plants in ocean preform photosynthesis and make sure there is enough oxygen
Development of living world: * Paleontology science which studies fossils * FossilsPreserved Old traces, remains of living organisms from the past * Earth’s eras (4) 1. PRECAMBRIAN ERA * 4.5 billion-570 mil * Earth, oceans were created, earth cooled down, atmosphere started to form * Algae & bacteriafirst life * Corals, sponges & snailsfirst animals 2. PALEOZOIC ERA * 570 mil-225 mil * Beginningonly sea animals & plants * Laterfirst fish, amphibians, early reptiles & giant insects, first land animals & plants
3. MESOZOIC ERA * 225 mil-65 mil * Dinosaurs, first mammals and birds, pine trees and ferns, first traces of flowering plants 4. CENOZOIC ERA * 65 mil-now * Development of birds and mammals (first traces), flowering plants developed, traces of man * ‘’Mammals era’’
Microbiology
Viruses: * Reproduce (x)=Replicate (√) * Viruses are organisms on the border of living and non-living
