Natural resources - Khan Academy video Quiz

What is the main focus of the video?

• The adaptability of humans
• The importance of natural resources
• The distribution of non-renewable resources
• The impact of human activities on resources

2. According to the video, what are natural resources?

• Anything found in nature that can be used by animals
• Anything found in nature that can be used by humans
• Anything found in nature that can be used by plants
• Anything found in nature that can be used by insects

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

• Renewable resources can be replenished over a human lifetime, while non-renewable resources take longer to be replaced.
• Renewable resources can be replenished over a human lifetime, while non-renewable resources cannot be replaced.
• Renewable resources take longer to be replaced, while non-renewable resources can be replenished over a human lifetime.
• Renewable resources cannot be replaced, while non-renewable resources take longer to be replenished.

4. How are non-renewable resources like soil, minerals, and fossil fuels often distributed on Earth?

• Evenly distributed across the Earth's surface
• Concentrated in the places where they first formed
• Randomly distributed without any pattern
• Mostly found in underwater locations

5. What are metal ores?

• Rocks that contain valuable metals that people can extract
• Rocks that contain valuable gemstones that people can extract
• Rocks that contain valuable fossils that people can extract
• Rocks that contain valuable soil that people can extract

6. Where are most porphyry copper deposits found?

• Along the coastlines of the Pacific Ocean
• In subduction zones along tectonic plate boundaries
• In Eurasia and Australia
• In places with high wind speeds

7. How do non-renewable resources like metal ores form?

• They form through tectonic activity and erosion
• They form through weathering and erosion
• They form in magma chambers and uplift towards the surface
• They form in places with low wind speeds

8. Why can renewable natural resources be unevenly distributed across Earth?

• Because they are formed by geologic processes
• Because they are influenced by human activities
• Because of Earth's tilt and other factors
• Because they are only found in specific locations

9. How can human activities impact the distribution of natural resources?

• By extracting resources and transporting them all over the world
• By building dams and redistributing water
• By overexploiting resources and drying them up
• All of the above

10. What is the main message of the video?

• Humans are dependent on natural resources for survival
• The distribution of resources is unfair and unequal
• Human activities can have negative impacts on resources
• With careful management, everyone can thrive regardless of resource disparities
