Let’s go step by step to answer each question on the worksheet.

Lesson Review:
1.
What is one example of Earth’s sphere of influence on human society?
→ The atmosphere (air) affects humans because we need clean air to breathe. If pollution makes the air dirty, people can get sick. So, Earth’s atmosphere directly impacts human health and daily life.
2.
Which natural disaster might be the “hardest” to predict?
→ Earthquakes are often the hardest to predict. Scientists know where they’re likely to happen (like near fault lines), but they can’t say exactly when or how strong they’ll be — unlike hurricanes or floods, which give more warning signs.
3.
How do scientists use science to solve problems?
→ Scientists observe what’s happening, ask questions, test ideas with experiments or data, and then share their results. For example, if a river keeps flooding, scientists study rainfall, soil, and maps to figure out why — and then suggest ways to stop it, like building levees or planting trees.

Real Challenge:
4.
Do you think that American land should be protected by law? Why or why not?
→ Yes, American land should be protected by law. Why? Because land gives us clean water, fresh air, food, and places for animals to live. If we don’t protect it, factories or cities might pollute rivers or cut down forests — and that hurts everyone, even future generations. Laws help make sure no one ruins the land just for short-term profit.
5.
Some companies promise to clean up their impact on nature. Explain why you think these promises either require or have value in themselves.
→ These promises have value — but only if they’re real and checked by others. A company saying “we’ll plant trees” sounds good, but if they don’t actually do it, it’s just words. Real value comes when there are rules or groups watching to make sure they follow through. Otherwise, it’s just advertising.
6.
Why do you think most people live close to half of the world’s population?
→ Most people live near coasts or rivers because those areas have fresh water, fertile soil for farming, and easy transportation (ships, boats). Also, many big cities started near water long ago — so over time, more people moved there for jobs, schools, and services. It’s easier to survive and grow communities near water.

Final Answer:
1. Earth’s atmosphere provides clean air needed for human survival.
2. Earthquakes are the hardest natural disasters to predict.
3. Scientists solve problems by observing, testing, analyzing data, and sharing solutions.
4. Yes — laws protect land from pollution and destruction, ensuring resources for all.
5. Company promises have value only if enforced; otherwise, they’re empty claims.
6. People live near water sources for access to food, transport, and historical settlement patterns.
