In a class of Senior 3, a geography teacher called Mr Shema wa how human activities such as deforestation and bush burning ha affected Ozone layer which led to Ozone layer depletion. Among the following atmospheric layers, which layer contains

Here are the answers to your questions: 6) i) Among the following atmospheric layers, which layer contains the Ozone layer? The ozone layer is found in the stratosphere. c) Stratosphere. ii) How is the Ozone layer important to us? The ozone layer protects life on Earth by absorbing harmful ultraviolet radiation from the sun. It also plays a role in regulating atmospheric temperatures. d) A and B are correct answers. 7) Analyze the impact of relief features on: a) Settlement: Relief significantly influences settlement patterns. Flat plains and gentle slopes are generally preferred for settlements due to ease of construction, accessibility, and availability of fertile land for agriculture. Steep slopes and mountainous areas often have sparse settlements because of difficult terrain, poor accessibility, and higher risks of natural hazards like landslides. b) Agriculture: Relief affects agricultural practices by influencing soil depth, drainage, temperature, and exposure to sunlight. Flat, low-lying areas with deep, fertile soils are ideal for extensive cultivation. Hilly or mountainous regions may require terracing for farming, and the aspect of a slope (which way it faces) can determine the amount of sunlight and moisture available for crops. 8) How do the following factors influence the vegetation of a place? a) Relief: Relief influences vegetation by affecting temperature, precipitation, and soil conditions. Higher altitudes typically experience lower temperatures and different precipitation regimes, leading to distinct vegetation zones (e.g., tropical rainforests at low altitudes, montane forests, and alpine meadows at higher altitudes). Slope steepness and aspect also impact water retention and sun exposure, influencing the types of plants that can thrive. b) Human activities: Human activities have a profound impact on vegetation. Deforestation for agriculture, logging, urbanization, and infrastructure development directly remove natural vegetation. Conversely, activities like reforestation, conservation efforts, and the establishment of protected areas can help preserve or restore vegetation. Pollution and the introduction of invasive species can also alter natural plant communities. 3 done, 2 left today. You're making progress.
