Front

What is solar energy?

Back

Solar energy is energy harnessed from the sun's rays, often using solar panels to convert it into electricity.

Front

How are fossils created?

Back

Fossils are created when traces of organisms are turned into stone, typically through the quick burial of dead organisms over millions of years.

Front

What is the main environmental benefit of renewable energy resources compared to fossil fuels?

Back

Renewable energy resources produce less pollution than fossil fuels.

Front

How is geothermal energy harvested?

Back

Geothermal energy is harvested by using the heat from the earth to boil water, creating steam that can be used to generate electricity.

Front

What is biomass energy?

Back

Biomass energy is produced from organic materials, such as plant and animal waste, which can be burned or converted into biofuels.

Front

What is wind energy?

Back

Wind energy is generated by converting the kinetic energy of wind into mechanical power or electricity using wind turbines.

Front

What is the difference between renewable and non-renewable energy sources?

Back

Renewable energy sources can be replenished naturally, while non-renewable energy sources, like fossil fuels, are finite and will deplete over time.

Front

What is the role of solar panels?

Back

Solar panels collect sunlight and convert it into electricity for use in homes and businesses.
