Vegetation cover and aspect influence temperature Temperature is always higher on exposed slopes more variable on exposed s slopes always lower on forested slopes. less variable on exposed N slopes. related to slope position but not vegetation. Solution B) More variable on exposed S slopes. From the graph we can see temperature variation of S slopes. For S-ex slope temeprature varies from 15°C to 35-36°C reaching the peak at 37°C and the slides down again to20°C..
