Discuss the various factors responsible for uneven temperature distribution on earth's surface (Answer in 150 words) 10 Marks
Introduction
Earth's heat budget, although uniform is unevenly distributed across regions, latitudes & altitude

Main Body
Uneven temperature distribution:
1Temperature reduces with height - cold at top, warm at equator, warm at sea level. Regional distribution with large valley and latitude wise distribution
2Uneven distribution on earth's surface
Factors:
1Land-sea differential due to specific heat capacity of water - northern hemisphere warmer due to more land
2Altitude as a factor as density of air reduces with height
3Insolation from sun causes differential in temperature distribution - Temp: equator > Tropics > Polar at 23.5°
4Tilt of earth at its axis also plays a role in differential heating
5Anthropogenic factors:
(a) Deforestation leading to poor albedo & higher absorption - cutting of trees increase microtemp. across amazon
6Glaciers also play a role
(ex)- Volcanic eruption reduces regional temp.
forest fires (burnt trees)
Climate change has led to major disruption in the heat distribution in recent years
