Exploring Creation with Physical Science Module #2

Humidity – The moisture content of air

Absolute Humidity – The mass of water vapor contained in a ceratin volume of air

Relative Humidity – The ratio of the mass of water vapor in the air at a given temperature to the maximum mass of water vapor the air could hold at that temperature, expressed as a percentage

Greenhouse Effect – The process by which certain gases (principally water vapor, carbon dioxide, and methane) trap heat that radiates from earth

Lyrics:

What does the glass of a greenhouse do?
It lets the short solar rays pass through.
The objects in the house absorb these rays
And re-radiate them as long heat rays.
What does the glass of a greenhouse do?
It doesn’t let the long heat rays pass through.
Trapped by the glass they bounce back and forth,
Re-radiated and re-absorbed.
Stay! Stay, you long heat rays!
Warm up the house on cold, cold days!
Stay! Stay, you long heat rays!
Warm up the house on cold, cold days!
The atmosphere is like a greenhouse, too.
It lets most of the solar rays through.
The surface of the Earth absorbs these rays
And re-radiates them as long heat rays.
There’s vapor in the air, what does it do?
It doesn’t let the long heat rays pass through.
Trapped by the vapor, they bounce back and forth
Re-radiated and re-absorbed.
Stay! Stay, you long heat rays!
Warm up the house on cold, cold days!
Stay! Stay, you long heat rays!
Warm up the Earth on cold, cold days!

Global warming = the concentration of carbon dioxide (and other greenhouse gases) being so great that the greenhouse effect would warm the earth up too much, causes problems with the ecological balance. 

Global Warming???

What is Ozone? A molecule composed of three oxygen atoms. It is an AMAZING filter!

Ozone: Good up high, bad nearby.
