What is heat?

form of energy that can be transferred from one object or substance
to another. It’s what causes things to warm up or cool down

What is temperature

How hot ir cold an object is

How does an object's temperature affect the wavelength of the light or radiation it emits?

• The hotter the object, the shorter the wavelength

• The colder the object, the longer the wavelength

Energy balance

When the incoming and outgoing energy
are equal, Earth is in radiative equilibrium
and its global temperature is relatively
stable.

Heat transfer is

Conduction, Convection and Radiation

what is conduction

Heat is transferred through direct contact between objects

what is convection?

Heat us transferred within fluid that is in motion, such as liquid or gas

what is radiation

Heat is transferred through space without material carrier by electromagnetic radiation

what is albedo

The fraction of sunlight that is reflected by a body or surface

High albedo is

sand, snow, ice, clouds

low albedo is

forest, oceans and asphalt

What is Diurnal Variation

Diurnal VAriation is the change in tempature from day to night brought about by the daily rotation of the earth.

What seasonal Vartiation

The change in tempature over the four season

what does variations with topography mean

Tempature variations induced by water and terrain

What does variation with latitude

Temperature varies with latitude. The
equator is warmer and receives more
radiant energy than Earth’s poles
