Flashcards

What are natural resources?

Things provided by the Earth, including valuable metals, gases, plants, sunlight, and animals. They have been used by humans since prehistoric times.

What are biotic resources?

Resources that are living or derived from living things, such as plants, animals, and fossil fuels.

What are abiotic resources?

Resources that are derived from non-living things, such as different metals like copper.

What are finite resources?

Resources that have a limited supply and will eventually run out.

Study Notes

Natural Resources

Natural resources are materials provided by Earth, including metals, gases, plants, sunlight, and animals. Humans have used them since prehistoric times.

Types of Natural Resources

Categorization: Natural resources are categorized as biotic or abiotic.
Biotic Resources: Living things or materials derived from them (plants, animals, fossil fuels like coal, oil, and natural gas).
Abiotic Resources: Non-living things (metals like copper).

Resource Use Over Time

Increased Usage: Resource use has increased with population growth and improved extraction methods.

Resource Availability

Categorization: Resources are classified as renewable, non-renewable, or sustainable.
Renewable Resources: Resources that can be used repeatedly without running out (e.g., wind power).
Non-renewable Resources: Resources with limited supply and will eventually run out (e.g., coal, oil).
Sustainable Resources: Renewable resources that require management to remain available (e.g., replanting trees for wood, managing fish stocks for fishing).

Resource Management

Finite Resources: Resources with a limited supply and will eventually run out (e.g., coal, oil).
Sustainable Resource Management: Essential for maintaining the availability of renewable resources. Examples include replanting trees and allowing fish stocks to recover.
