CANVAS Unit 5 ES Minerals and Fossil Fuels Flashcard

Front

What are native elements in mineralogy?

Back

Native elements are minerals that are composed of a single element, such as gold, silver, and copper.

Front

What is a mineral?

Back

A mineral is a naturally occurring, inorganic solid with a definite chemical composition and a crystalline structure.

Front

What is the difference between renewable and non-renewable resources?

Back

Renewable resources can be replenished naturally over time (e.g., solar energy), while non-renewable resources exist in finite amounts and cannot be replaced (e.g., natural gas).

Front

What is passive solar heating?

Back

Passive solar heating is a method of using the sun's energy to heat buildings directly without mechanical systems, typically through design features like large windows.

Front

Why is nuclear power considered expensive?

Back

The electricity from nuclear power is generally more expensive to produce than electricity from other sources due to high initial construction costs and regulatory requirements.

Front

What are gangue minerals?

Back

Gangue minerals are the unwanted materials that are extracted along with valuable minerals during mining.

Front

What is the significance of a mineral's characteristic chemical composition?

Back

A mineral's characteristic chemical composition defines its identity and properties, distinguishing it from other minerals.

Front

What are fossil fuels?

Back

Fossil fuels are natural substances formed from the remains of ancient organisms, including coal, oil, and natural gas.

Front

What is the role of geothermal energy?

Back

Geothermal energy harnesses heat from the Earth's interior for electricity generation and direct heating applications.

Front

What is biomass fuel?

Back

Biomass fuel is derived from organic materials, such as plant and animal waste, and can be used for energy production.
