Grade 3 Environmental Activities – Effects of unfavourable weather conditions Quiz
1. What is the primary reason for landslides occurring during heavy rainfall in Kenya?
Deforestation reduces the stability of the soil, making it more prone to landslides. Planting trees helps prevent landslides by holding the soil together.
2. Which activity contributes to the depletion of the ozone layer and leads to unpredictable weather patterns?
Burning fossil fuels releases harmful chemicals into the atmosphere which deplete the ozone layer and contribute to unpredictable weather patterns.
3. What effect does excessive use of pesticides and fertilizers have on the environment?
Excessive use of pesticides and fertilizers can run off into water bodies, causing pollution and harm to aquatic life.
4. How does deforestation impact the climate of an area?
Deforestation can lead to desertification as the trees that help retain moisture in the soil are no longer present, causing the land to become dry and arid.
5. What is a possible consequence of global warming on Kenya's wildlife?
Global warming can disrupt ecosystems and lead to changes in habitats, potentially causing the extinction of certain species unable to adapt to the new conditions.
6. How does overfishing contribute to environmental degradation?
Overfishing can disrupt the natural balance of ecosystems by depleting the population of certain fish species, leading to cascading effects on other species in the food chain.
7. Why is it important to practice sustainable agriculture in Kenya?
Sustainable agriculture practices help conserve water resources by minimizing water wastage and reducing the impact of farming activities on local water sources.
8. What can be a result of heavy deforestation in Kenya's forests?
Heavy deforestation can result in the loss of wildlife habitat as animals that depend on the forest for shelter and food are displaced or endangered.
9. How does air pollution affect human health in Kenya?
Air pollution can lead to respiratory illnesses such as asthma and bronchitis, particularly in vulnerable populations like children and the elderly.
10. What impact does illegal logging have on Kenya's forests?
Illegal logging contributes to deforestation and habitat destruction, leading to loss of biodiversity and disruptions in ecosystem functioning.
