Factors responsible for uneven temp distribution:

1. Earth's tilt of 23.5°Cpresence of various seasons and climate

2. Latitudinal differencecausing variability in insolation [E.g] Equator — highest insolation, poles — lowest insolation

3. Topographic factorHigher the altitude, lower the temperature. [E.g] Every 165 m from sea level, temperature decreases by 1°C

4. Global wind circulationDue to presence of high pressure zones

[5.0] Creation of deserts due to lack of cloud formation over 30°-40° latitude due to high pressure.

5. Ocean currents & — Cold ocean currents bring dry cold airmassLower temperature over the coastal region [E.g] Atacama desert near Peru current.

6. Atmospheric disturbances like formation of frontal rainfall, orographic rainfall as well cyclonic circulator also impact temperature.
