ASSIGNMENT 2 2025
UNIQUE NO.
DUE DATE: 2 JULY 2025
, QUESTION 1 [15 Marks]
Based on HES4810 Lessons: Environmental Aspects and Human Impact
1.1 Climate (3)
Three human activities impacting climate:
Fossil fuel combustion: Releases greenhouse gases (CO₂, CH₄) into the
atmosphere, contributing to global warming.
Deforestation: Reduces carbon sequestration capacity, increasing CO₂ levels.
Industrial processes: Emit pollutants and gases (e.g., refrigerants, nitrous
oxide) that contribute to the greenhouse effect.
1.2 Topography (3)
Three human activities impacting topography:
Mining and quarrying: Change natural land contours and create pits/hollows.
Urban development: Levels and reshapes landscapes for construction.
Dam construction: Alters river paths and affects surrounding elevation and
slopes.
1.3 Soil (3)
Three human activities impacting soil:
Overgrazing: Leads to soil compaction and erosion.
Agricultural activities: Excessive fertilizer use leads to salinization and
degradation.
Construction: Removes topsoil, leading to reduced fertility and increased
erosion.
1.4 Geology (3)
Three human activities impacting geology:
