Where are Fossil Fuels Found? Fossil fuels are found in many parts of the world, both on land and beneath the sea.

How do Humans Obtain Fossil Fuels? Humans use different methods to remove fossil fuels depending on the type of fuel being obtained.

Strip Mining Strip mining is the process in which rock and soil are stripped from the Earth’s surface to expose the underlined materials to be mined.

Strip Mines Strip miners use explosives to blast away rock and soil to expose the materials to be mined.

Oil Rigs Large oil rigs, some more than 300 m tall, operate in many places, such as the gulf of Mexico and the North Sea.

Problems with Fossil Fuels Fossil fuels provide energy for our technological world, the methods of obtaining and using them can have negative consequences on the environment.

Acid Precipitation Acid precipitation can exist as rain, snow, mist, or any other form of precipitation.
