New Unit: Water, Air, & LandKey Questions:

1)Why are water, air, and land critical to human survival?

2)How does our way of life contribute to pollution and overuse of resources?

3)How have people and governing bodies worked toward conservation?

Chapter 11: WaterSection 1: Water Resources- Distribution of Earth’s water

Section 2: Water Use & Management- How people use water; conservation

Section 3: Water Pollution- Types and sources of water pollution

Water is a limited resource- Earth’s water consists of salt water and fresh water.- 71% of Earth’s surface is covered in water; 97% is salt water- 77% of Earth’s fresh water is frozen

The Water Cycle:• Water molecules travel between earth’s

surface and the atmosphere• Evaporation: Water leaves behind

salts/impurities and rises as water vapor• Condensation: Water vapor condenses into

liquid and forms clouds• Precipitation: Water falls to the ground:

enters surface water or groundwater

Surface Water:• http://www.unwater.org/worldwaterday/anim

• Surface water: fresh water on Earth’s surface• Lakes, rivers, streams, wetlands• River system:a network of streams that flow

into larger rivers• Provide drinking water, transportation, food• Most major cities were built by surface water

Surface Water:• Watershed: the area of land that is drained

by a river• Pollution anywhere in the watershed can

affect the entire river system
