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.
Develop and use models of Earth’s interior composition to illustrate the resulting magnetic field (e.g., magnetic poles) and to explain its measureable effects (e.g., protection from cosmic radiation).
