Which city has the least amount of precipitation each year? 4. Which city has the largest difference between daily use and annual precipitation?

An example. . .

Greenhouse Effect Increasing temperature of the Earth caused by trapping greenhouse gasses (like CO 2 , CH 4 , and N 2 O)

Greenhouse Effect

Global Warming: The gradual increase in the average temperature of Earth believed to be caused by increased greenhouse gasses to human processes. Best described as climate change

*More fossil fuels byproducts found in air, water, plants
