Environmental Conservation - SS2 Geography Past Questions and Answers - page 2
Which of the following is a negative impact of deforestation?
Increased carbon sequestration
Enhanced biodiversity
Soil erosion
Reduced greenhouse gas emissions
Sustainable agriculture practices aim to:
Maximize resource exploitation
Increase pollution
Minimize harm to the environment
Promote deforestation
Which farming practice helps in conserving soil fertility, reducing erosion, and preventing weed growth?
Crop rotation
Precision agriculture
Cover cropping
Excessive tilling
What is the main objective of afforestation in environmental conservation?
Decrease tree density
Restore degraded forests
Increase industrial pollution
Maximize soil erosion
How does re-afforestation differ from afforestation?
Re-afforestation aims to create new forests.
Afforestation involves replanting trees in deforested areas.
Both terms are synonymous
Re-afforestation is a destructive practice.
Explain the concept of environmental conservation in your own words
Environmental conservation means taking actions to protect and preserve the environment by using resources responsibly and minimizing negative impacts.
Describe the key benefits of afforestation and re-afforestation in environmental conservation.
Afforestation and re-afforestation help by increasing tree cover, which reduces carbon in the atmosphere and preserves biodiversity.
How does cover cropping contribute to soil health in agriculture?
Cover cropping improves soil health by preventing erosion, maintaining fertility, and controlling weeds.
Name and explain two improved farming techniques that promote sustainable agriculture.
Two improved farming techniques are crop rotation (diversifying crops to prevent soil depletion) and reduced tillage (minimizing soil disturbance).
Why is it important to adopt precision agriculture in modern farming practices?
Precision agriculture is important as it optimizes resource use, reducing waste and pollution, while enhancing crop yields and minimizing environmental impacts.
