Introduction

The Earth's heat budget is a fundamental concept, and however, the distribution of heat depends on various factors.

Main Body

(i) Latitude of Earth.

[Diagram showing sun rays, tropics, high latitudes, mid-latitudes]

The higher the latitude, the lower the insolation and so lower heat (some heat cover more area due to slanted rays)

(ii) Season (Tilt of the earth according to time of year):

[Diagram showing Earth's tilt and seasons with sun rays from different angles]

The higher the latitude the more the day length, hence more heat.

Continentality of the region:

Regions farther lying on major sea breeze less winds from ocean and show greater temperature extremes

Temperature most at low altitude (low range) due to effect of the sea (sea breeze) and breeze.

ii) Altitude: Himalayas are colder because mountains are further away from heat emanating surface of the earth.

iii) Wind, Ocean Current transfer heat from low to high prime. Thus, various factors affect the distribution of heat on Earth.
