Transcript of Copy of Simple? ...Not too Simple


Alternative Fuel

Alternative fuels, known as non-conventional or advanced fuels, are any materials or substances that can be used as fuels, other than conventional fuels.
Some well-known alternative fuels include biodiesel, bioalcohol (methanol, ethanol, butanol), chemically stored electricity (batteries and fuel cells), hydrogen, non-fossil methane, non-fossil natural gas, vegetable oil, and other biomass sources.

According to the volcanism hypothesis, this global-scale volcanic activity spewed so much gas, ash, and dust into the atmosphere that it kept sunlight from reaching Earth's surface. Temperature and plant production plummeted, and dinosaurs and many other organisms that were poorly adapted to the harsh conditions perished.
Scientific evidence and observation are the building blocks of hypotheses. Initially, the same evidence and observations may support different hypotheses. As more evidence becomes available, some hypotheses are substantiated, others are disproved, and new ones are formed.

According to scientists who maintain that dinosaur extinction came quickly, the impact must have spelled the cataclysmic end.
