The exhaust from car engines spreads throughout our atmosphere and adds to pollution. What is this an example of?A.An increase in thermodynamicsB.An increase in enthalpyC.An increase in thrustD.An increase in entropySUBMITarrow_backPREVIOUS

An increase in automobile use has led to increased demand for fuel. The extraction, processing, and delivery of fuel put harmful pollutants into the atmosphere. The fuel that is then consumed by engines creates carbon dioxide emissions. The carbon dioxide creates a greenhouse effect in the atmosphere. The gasses trap heat in Earth's atmosphere, leading to global warming.Which statement best describes the main idea of this passage?A.People should reduce their use of automobiles or drive cleaner vehicles.B.Life was better before the invention of automobiles.C.Most people are unaware of how air pollution affects the environment.D.Mass transit creates less air pollution than individual automobiles.SUBMITarrow_backPREVIOUS
