Climate Change Comparison

Resources: Case studies from Ch. 20 of the text.
. Case 1: Water Issues in the Arid American Southwest
. Case 2: Soil Salinization in Arid and Semi-Arid Lands
Consider the following statements:
. Climate change is not only a scientific issue but also a political
issue.
. There is a relationship between human activity and physical geography
Create a comparison of the effects on Coastline Formations and Arid
Landscapes. Response in at least 70 per box.

| |are related to daily | |
| |oscillations and flow | |
| |patterns. Over long | |
| |periods of time, water | |
| |levels in oceans and | |
| |large lakes change for a | |
| |variety of reasons. For | |
| |instance, changes can | |
| |occur when tectonic | |
| |forces cause a landmass | |
| |to be uplifted or sink. | |
| |Water levels also | |
| |fluctuate when the amount| |
| |of water in the ocean or | |
| |lake varies as a result | |
| |of adjustments in the | |
| |hydrologic cycle. This | |
| |form of water-level | |
