A.5 Water Use in the Economy

1.  a.     The East: steam and electric b.     The South: steam and electric c.     The Midwest: steam and electric d.     The West: irrigation and agricultural e.     Alaska: mining f.      Hawaii: irrigation and agricultural

2. In the East, there are more factories, so water is essential for those industries and is used mostly for steam and electric purposes. In the West, most people live on the farms, which are the majority of land, and water is used mostly for irrigation and agricultural purposes.

3.               a.     The East

In the East, the industries and seasonal changes are two factors that could explain the greatest water use (steam and electric) within the region.

b.     The South

In the South, the industries and seasonal changes are two factors that could explain the greatest water use (steam and electric) within the region.

c.     The Midwest

In the Midwest, the factories and seasonal changes are two factors that could explain the greatest water use (steam and electric) within the region.

d.     The West

In the West, there are many farms and the moderate temperatures could explain the greatest water use (irrigation and agricultural) within the region.

e.     Alaska

In Alaska, the cold weather and industrial economy could explain the greatest water use (mining) within the region.

f.      Hawaii

In Hawaii, the plentiful lands and reasonable climates could explain the greatest water use (irrigation and agricultural) within the region.
