Front

What is the primary component of natural gas?

Back

Natural gas consists mostly of methane (CH4).

Front

What fuel is used in nuclear power plants?

Back

Nuclear power uses uranium as fuel.

Front

How does coal form?

Back

Coal forms from dead plant material that temporarily decays in a swamp environment.

Front

What major air pollutant from coal do scrubbers help remove?

Back

Scrubbers help remove sulfur, a major air pollutant from coal.

Front

What happens to kinetic energy as the speed of an object increases?

Back

The faster an object moves, the more kinetic energy it has.

Front

Define renewable energy resources.

Back

Renewable energy resources are energy sources that can be replenished naturally, such as solar, wind, and hydroelectric power.

Front

What is the difference between fossil fuels and renewable energy?

Back

Fossil fuels are non-renewable energy sources formed from ancient organic matter, while renewable energy comes from natural processes that are continuously replenished.

Front

What is the process of photosynthesis in relation to energy resources?

Back

Photosynthesis is the process by which plants convert sunlight into chemical energy, forming the basis of the food chain and contributing to biomass energy.

Front

What is the environmental impact of burning coal?

Back

Burning coal releases pollutants such as sulfur dioxide, carbon dioxide, and particulate matter, contributing to air pollution and climate change.

Front

What is geothermal energy?

Back

Geothermal energy is heat energy generated and stored in the Earth, which can be used for heating and electricity generation.
