Factors affecting climate in Tanzania

Major factors affecting the climate of Tanzania

1. Altitude: Higher altitudes experience cooler temperatures, while lower altitudes are generally warmer.
2. Vegetation: Dense vegetation can affect humidity, temperature, and rainfall patterns.
3. Distance from the Sea or Lake: Coastal areas have more moderate climates, while inland areas experience more extreme temperatures.
4. Wind: Wind patterns influence rainfall and temperature by carrying moist or dry air.
5. Latitude: Tanzania's position near the equator results in a tropical climate with warm temperatures year-round.
