20.14 & 20.15 Quiz: Geothermal and Biomass Energy

(a)   energy comes from underground pockets of hot water.

• hydroelectric

• nuclear

• solar

• geothermal

Answer explanation

Geothermal energy is derived from underground pockets of hot water, making it the correct choice. Hydroelectric, nuclear, and solar energies come from different sources, not from underground water.

What is biomass?

• Human made objects

• Plants that can be used for fuel

• Oil, gasoline, and coal

• large amounts of water

Answer explanation

Biomass refers specifically to organic materials, particularly plants, that can be used as fuel. This makes 'Plants that can be used for fuel' the correct choice, as it directly defines what biomass is.

What is one type of biomass energy?

• Plastic

• Sun

• Wood

• Oil

Answer explanation

Wood is a type of biomass energy derived from trees and plants, making it a renewable resource. Unlike plastic or oil, which are not biomass, wood can be used for fuel and energy production.

The most common way to release biomass is?

• Bacterial Decay

• Fermentation

• Conversion

• Burning

Answer explanation

The most common way to release biomass is through burning. This process converts organic material into energy, releasing carbon dioxide and other gases, making it a prevalent method for biomass energy production.

Biomass & Geothermal Energy are:

• Renewable

• Non-Renewable

Answer explanation

Biomass and geothermal energy are considered renewable because they are derived from natural processes that can be replenished over time, unlike non-renewable resources which are finite.

Which is NOT an example of Biomass?

• wood

• crops

• wind

• animal dung

Answer explanation

Biomass refers to organic materials that can be used for energy, such as wood, crops, and animal dung. Wind, however, is a renewable energy source but not biomass, making it the correct answer.

Dung is the excrement of animals; manure.

• True

• False

Answer explanation

Dung refers to the excrement of animals, commonly used as manure. Therefore, the statement is true.

What is geothermal energy?

• Energy from the Sun

• Energy made by wind spinning a turbine

• Energy collected using the heat of the Earth

• Energy collected by a hamster running on a wheel connected to a generator

Answer explanation

Geothermal energy is derived from the heat stored within the Earth. This heat can be harnessed for various uses, making the correct choice "Energy collected using the heat of the Earth." The other options describe different energy sources.

At what time is geothermal energy available?

• Day

• Night

• All day

• Never available

Answer explanation

Geothermal energy is available all day because it relies on the Earth's internal heat, which is constant and not dependent on sunlight or time of day.

Geothermal energy produces pollution: True or False?

• True

• False

Answer explanation

Geothermal energy is considered a clean energy source. While it can produce some emissions, they are significantly lower than fossil fuels, making the statement that it produces pollution generally false.
