M8 "Energy Sources and the Environment"

Front

What is nuclear fission?

Back

Nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller parts, releasing a large amount of energy. It is the process used in nuclear power plants to generate electricity.

Front

What are the environmental benefits of nuclear power?

Back

Nuclear power produces large amounts of energy with minimal air pollution and greenhouse gas emissions compared to fossil fuels.

Front

What does it mean to conserve energy?

Back

To conserve energy means to reduce energy consumption and use less energy whenever possible, helping to protect the environment.

Front

What materials do solar cells use to generate electricity?

Back

Solar cells use semiconductor materials, such as silicon, to absorb sunlight and eject electrons, creating an electric current.

Front

What is a photovoltaic cell?

Back

A photovoltaic cell is a device that converts radiant energy from sunlight directly into electrical energy.

Front

What is a nonrenewable resource?

Back

A nonrenewable resource is a natural resource that cannot be replaced by natural processes as quickly as it is consumed, such as fossil fuels.

Front

What is a renewable resource?

Back

A renewable resource is a natural resource that can be replenished naturally over time, such as solar energy, wind energy, and biomass.

Front

What is the role of turbines in energy generation?

Back

Turbines convert kinetic energy from wind, water, or steam into mechanical energy, which is then converted into electrical energy by generators.

Front

What are the main sources of renewable energy?

Back

The main sources of renewable energy include solar energy, wind energy, hydroelectric power, geothermal energy, and biomass.

Front

What is the impact of fossil fuels on the environment?

Back

The burning of fossil fuels releases greenhouse gases, contributing to climate change, air pollution, and environmental degradation.
