Natural Greenhouse Effect
What are the greenhouse gases?
Water vapour, carbon dioxide, nitrous oxide, methane
What is Net Radiation Budget?
The difference between the amount of incoming radiation and the amount of outgoing radiation
What is Albedo?
The percent of incoming solar radiations reflected by surface
How many natural greenhouse gases are there?
4
How does a greenhouse work?
Let solar radiation pass through the glass
Some of the radiation get reflected and escapes the through glass.
Thermal energy gets trapped
What is the equation?
Incoming Radiation - Outgoing Radiation = 0
Which one would produce more albedo? light coloured/ shiny surfaces or dark/duller surfaces?
Light coloured/shiny surfaces
Insolation is a mashup of words. What were the word used to create the word “Insolation”?
Incoming Solar Radiation
What is insolation and what are the 4 factors that affect it?
Insolation: the amount of solar radiation each region receives. The 4 factors are latitude, atmosphere, lithosphere, hydrosphere
What would happen if the amount of out going radiation decreases and the amount of incoming radiation stays the same?
Global Temperature increases
How much more does light coloured/shiny surfaces reflect than dark/duller surfaces by?
90%
which natural greenhouse gas is most present in the atmosphere?
Water Vapour
What is the global temperature since of last year (2025)?
14-15°C
How much is reflected/absorbed percentage wise?
30% reflected by clouds, atmosphere, earth's land surface
70% absorbed by atmosphere (23%), land surface and ocean (47%).
Why is that in Ontario, winter has a higher albedo than the summer time?
Snow and Frost
On the greenhouse Gases slide, which compound did I make?
Nitrous Gas (N2O)
What would the global temperature be without the natural greenhouse effect?
-20°C
How much watts does Earth receive on average each year?
342W
Does fresh snow have a higher albedo than ocean ice?
Yes, fresh snow has a higher albedo than ocean ice
On the first slide (Title Page), there was a star. How many vertices were on the star?
8
