What is Geothermal and Biomass Energy?
Within Earth & Environmental Science, which covers our planet, its resources and ecosystems, and how people can protect the environment, this topic explains Geothermal and Biomass Energy. Earth and environment topics show how the planet’s systems shape landscapes, climate and life, with models that make these processes visible.
Check that you can explain Geothermal and Biomass Energy in your own words and give one example from everyday life. If you can do that, you have understood the core idea.
Understanding Geothermal and Biomass Energy helps you explain the environment around you and weigh up how people can protect it.
Geothermal and Biomass Energy in detail
Geothermal energy uses heat from within the Earth. In places with hot rocks near the surface, such as Iceland, New Zealand and volcanic regions, steam or hot water drives turbines or heats buildings directly. It is reliable day and night, but limited to certain locations, and can release some gases.
Biomass energy comes from burning or processing organic material such as wood, crop waste, animal manure and energy crops, or converting it to biofuels such as bioethanol and biodiesel and biogas. It can be carbon neutral if plants regrow and absorb the carbon released, but growing crops for fuel can compete with food production, cause deforestation and use water and fertilisers.
How the interactive helps you understand Geothermal and Biomass Energy
Watch the energy stores in the interactive. Use any sliders or buttons it offers to change the values and see how the energy stores responds.
Before you change anything, predict the result. Then change one value at a time and check whether your prediction was right. This is a quick way to build a correct mental model of Geothermal and Biomass Energy.
Real-life uses and examples
- Use a diagram of Geothermal and Biomass Energy to describe the steps of a process in order.
- Discuss how human activity changes Geothermal and Biomass Energy, using a named example.
- Explain how Geothermal and Biomass Energy affects the landscape or climate near you.
Common mistakes to avoid
- Describing a process without the timescale it works over.
- Presenting one cause as the only cause of an environmental change.
- Learning the definition without testing it. Use the quiz and the interactive to check that you can apply the idea.
