Earth's Systems and Deforestation

Earth's spheres diagram showing interconnected systems

🌍 Part 1: Earth's Systems Knowledge Check

1. Match each Earth system with its correct description:
1. Geosphere
2. Atmosphere
3. Hydrosphere
4. Biosphere
A. All water on Earth including oceans, rivers, and ice
B. The layer of gases surrounding Earth
C. All living organisms and their environments
D. The solid, rocky part of Earth including soil and rocks
2. Which of the following is an example of interaction between Earth's systems? (Circle the best answer)

Plants (biosphere) absorbing water (hydrosphere) from soil (geosphere)

Rocks sitting on the ground

Fish swimming in the ocean

Clouds floating in the sky

🌳 Part 2: Deforestation Impact Analysis

3. Complete the following sentences about deforestation impacts on each Earth system:

Geosphere: When forests are cleared, the _____________ becomes loose and can be washed away, leading to _____________ erosion.

Atmosphere: Deforestation increases _____________ dioxide levels because trees can no longer absorb this gas through _____________.

Hydrosphere: Without tree roots to hold soil, more _____________ runs off into rivers and streams, causing water _____________.

Biosphere: Forest clearing destroys animal _____________ and reduces _____________.

4. Which of these are direct effects of deforestation? (Check all that apply)

Loss of animal habitats

Increased soil erosion

More carbon dioxide in the atmosphere

Cleaner water in rivers

Reduced biodiversity

Better air quality

🔗 Part 3: Cause and Effect Connections

5. Complete these "If-Then" statements using scientific reasoning:

If a large area of native New Zealand forest is cleared for farming, then _________________________________ because _________________________________.

If soil erosion increases due to deforestation, then _________________________________ because _________________________________.

If fewer trees are available to absorb carbon dioxide, then _________________________________ because _________________________________.

6. Draw a diagram showing how deforestation affects at least three of Earth's systems. Include arrows to show connections between systems.

🧠 Part 4: Critical Thinking and New Zealand Context

7. Explain how deforestation in one area of New Zealand could affect people living in a different region. Use specific examples of Earth's systems in your answer.
8. Suggest two practical solutions that could reduce the negative impacts of deforestation on Earth's systems:

Solution 1: ___________________________________________________________________

Solution 2: ___________________________________________________________________

9. Which Earth system do you think is most affected by deforestation? Justify your answer with evidence.

📝 Part 5: Reflection and Key Terms

10. Define these key scientific terms in your own words:

Interconnected: ___________________________________________________________________

Biodiversity: ___________________________________________________________________

Erosion: ___________________________________________________________________

Photosynthesis: ___________________________________________________________________

11. What is one new thing you learned about Earth's systems today?
12. What question do you still have about deforestation and Earth's systems?
