The Natives who were able to tame the Salt and Gila Rivers were known as the <u>Hohokam</u>.
<h3>Who were the Hohokam?</h3>
- They were a Native American civilization that lived in the North American Southwest.
- They constructed extensive irrigation works to use the waters of rivers.
The Hohokam were in dry areas and yet needed water to grow crops and survive. They therefore constructed some complex and extensive canals to channel water to their settlements and farms.

Answer:
The greenhouse effect is a natural process that warms the Earth's surface.
Explanation:
When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. Greenhouse gases are absorbed energy that warms the atmosphere and the surface of the Earth.
Natural process by which water soluble substances (such as calcium, fertilizers, pesticides) are washed out from soil or wastes. These leached out chemicals (called leachites) cause pollution of surface and sub-surface water.
