September 20

You take care of the earth and water it, making it rich and fertile.
   The river of God has plenty of water; it provides a bountiful harvest of grain, for you have ordered it so.
You drench the plowed ground with rain, melting the clods and leveling the ridges.
   You soften the earth with showers and bless its abundant crops.

Those who live at the ends of the earth stand in awe of your wonders.
   From where the sun rises to where it sets, you inspire shouts of joy.

Psalm 65:9-10, 8


This week we are looking at how changes in the atmosphere have ripple effects that influence our lives,  All of us have heard terms like “the Greenhouse Effect,” “Global Warming,” and “Climate Change.”  These are all related to changes in the composition of the atmosphere.  As the chemical composition changes, the temperature and functional properties of the atmosphere change as well.  You will find Chapter 4 very timely as these issues are on global political, economic, and environmental agendas.

Note that if you have the etext version, for LAB 2 QUESTIONS 13-16 you will need to use this Figure from the 4th Edition:  Figure 3.2 with Percentages (follow the link, open in a new tab)
