Evidence to support continental drift......
animals on continents and buildings look the same
oceans temperature increasing due to increased oxygen
fossils on different continenets and volcanoes forming
land looks like puzzle pieces and rock faces fit together
increasing CO2 in water makes it
more acidic
less acidic
warmer
colder
Humans increase CO2 in atmosphere by
increasing forest areas
burn fossil fuels
using renewable energy sources
converting to electric cars
