6SCI-Q2-T5 - Lesson 4.4: Mass Wasting and Glaciers

How can human activities contribute to mass wasting, and what strategies can be implemented to mitigate these effects?

• Human activities like deforestation and improper construction increase mass wasting; strategies include reforestation and terracing.

• Human activities like planting trees and building roads decrease mass wasting; strategies include deforestation and removing vegetation.

• Human activities have no impact on mass wasting; strategies include doing nothing.

• Human activities like farming and fishing increase mass wasting; strategies include building more roads.

Explain how the steepness of a slope affects the likelihood of mass wasting and propose a plan to stabilize a steep slope.

• Steeper slopes are less prone to mass wasting; stabilize by removing vegetation.

• Steeper slopes are more prone to mass wasting; stabilize by building retaining walls and planting vegetation.

• Steeper slopes have no effect on mass wasting; stabilize by doing nothing.

• Steeper slopes are more prone to mass wasting; stabilize by increasing the slope angle.

Analyze the role of natural events like earthquakes and volcanic activity in triggering landslides, and suggest preventive measures.

• Earthquakes and volcanic activity have no role in landslides; preventive measures include ignoring them.

• Earthquakes and volcanic activity can trigger landslides; preventive measures include monitoring and early warning systems.

• Earthquakes and volcanic activity prevent landslides; preventive measures include increasing construction.

• Earthquakes and volcanic activity are unrelated to landslides; preventive measures include deforestation.

Discuss the formation of talus and its significance in understanding mass wasting processes.

• Talus forms from volcanic eruptions and is unrelated to mass wasting.

• Talus forms from rockfalls and landslides, indicating areas of active mass wasting.

• Talus forms from river erosion and is unrelated to mass wasting.

• Talus forms from wind erosion and indicates stable slopes.

Evaluate the impact of poor land use practices on mass wasting and propose a comprehensive land management plan to reduce risks.

• Poor land use practices have no impact on mass wasting; no management plan is needed.

• Poor land use practices increase mass wasting; a plan should include reforestation and controlled construction.

• Poor land use practices decrease mass wasting; a plan should include more deforestation.

• Poor land use practices are unrelated to mass wasting; a plan should focus on urban expansion.

How do glaciers contribute to the shaping of landscapes through erosion, and what evidence supports this process?

• Glaciers do not erode landscapes; evidence shows no changes.

• Glaciers erode landscapes by plucking and abrasion; evidence includes U-shaped valleys and striations.

• Glaciers build landscapes; evidence includes mountain formation.

• Glaciers have no impact on landscapes; evidence is inconclusive.

Propose a method to study the effects of heavy rainfall on landslide occurrences in a specific region.

• Ignore rainfall data and focus on temperature changes.

• Collect rainfall data and correlate it with landslide occurrences to identify patterns.

• Study the effects of heavy rainfall on unrelated phenomena.

• Use rainfall data to predict volcanic eruptions instead.

Analyze the relationship between deforestation and increased landslide risk, and suggest a reforestation plan to mitigate this risk.

• Deforestation decreases landslide risk; no reforestation is needed.

• Deforestation increases landslide risk; a reforestation plan should focus on planting native species.

• Deforestation has no effect on landslide risk; reforestation is unnecessary.

• Deforestation stabilizes slopes; reforestation should be avoided.

Evaluate the effectiveness of terracing as a technique to prevent mass wasting on agricultural lands.

• Terracing is ineffective and increases mass wasting.

• Terracing is effective in reducing slope steepness and preventing mass wasting.

• Terracing has no impact on mass wasting.

• Terracing is only useful in urban areas, not agricultural lands.

Design a community awareness program to educate people about the risks of mass wasting and the importance of proper land use.

• Focus on unrelated topics like ocean pollution.

• Include information on mass wasting risks, proper land use, and emergency preparedness.

• Ignore mass wasting and focus on urban development.

• Emphasize the benefits of deforestation and construction.
