Biofuels are fuels that are derived from organic materials, such as plants or animal waste. These renewable energy sources can be used to power vehicles, heat homes, and generate electricity.
Types of Biofuels
There are several types of biofuels, including:
Ethanol: This is a type of alcohol that is produced by fermenting and distilling crops such as corn, sugarcane, or wheat.
Biodiesel: Made from vegetable oils, animalfats, or recycled restaurant greases through a process called transesterification.
Plan and carry out investigations that demonstrate the chemical and physical processes that form rocks and cycle Earth’s materials (e.g., processes of crystallization, heating and cooling, weathering, deformation, and sedimentation).
