Oil is a fossil fuel used to run cars, heat up homes, and produce electricity. Oil can be removed from the
bottom of the ocean through drilling. Drilling machines dig deep down into the Earth. When oil is found,
pipes carry it to the surface. Sometimes, accidents happen that cause the oil to spill into the oceans. The
oil can not only kill marine organisms, but when it reaches the surface of the water, some chemicals
evaporate, become part of the atmosphere, and pollute the air.
