Environmental hazards are hazards that affect biomes or ecosystems. [1] Well known examples include oil spills , water pollution , slash and burn deforestation, air pollution , ground fissures , [ 2 ] and build-up of atmospheric carbon dioxide . [ 3 ]
Balloon rockets work because the elastic balloons contract on the air within them, and so when the mouth of the balloon is opened, the gas within the balloon is expelled out, and due to Newton's third law of motion, the balloon is propelled forward. This is the same way that a rocket works.
Synchronized weather balloon launches have helped meteorologists create forecasts over the past 150 years, and now the old tradition is going high tech. Twice a day - every day of the year ...
