How to calculate °C to K
°C +273
Define Insolation
How much energy is absorbed by the earth’s surface per unit area
Where do you get low isolation and why
It is less at the poles as there are less rays per unit area. The rays travel further across a wider area.
Where do you get high isolation and why
At the equator
There are more rays per unit area, the heat energy transfer is greater
How does the tilt of the earth affect isolation
If the earth is tilted closer to the sun the rays don’t travel as far therefore stronger upon the surface
Name materials that absorb heat the most
Trees
Concrete
Sand
Name materials that absorb heat less
Any form of water
Name the ways the sun heats up the air
Conduction
Convection
Radiation
What is conduction
When the air closest to the surface is in contact gets heated up
What is convection
The warmer air expands as it is heated so the density decreases and the air rises
What is latent heat
The air slowly condenses and starts to release heat back into the atmosphere which is latent heat
What is turbulence heating
When the wind interacts with the hot air, mixing it around
