  1. Mr. Burton 2.2 notes Please Grab:1. Your folder.2. Writing Utensil.3. Answer the following question: How much of the earth do you think water covers? (Percentage, fractions, etc.)

  2. Water • Water covers some two-thirds of the planet. • About 97 percent of the Earth’s water • Unsafe to drink because of high levels of salt • In general, found in Earth’s oceans, which cover some 71 percent of the planet’s surface • Also found in some of Earth’s lakes • Water without salt • Makes up only 3 percent of our water supply

  3. Freshwater • Much of Earth’s freshwater is locked in glaciers, large areas of slow moving ice, and in the ice of the Arctic and Antarctic regions. • Surface water is water that is found in Earth’s streams, rivers, and lakes. • Less than one percent of Earth’s water supply • Streams, rivers, and lakes are common sources. • Precipitation is water that falls to Earth’s surface as rain, snow, sleet, or hail. • Streams form when precipitation collects in a narrow channel and flows toward the ocean. • Most available freshwater is groundwater, water found below Earth’s surface. • Some naturally bubbles from the ground to the surface as a spring. • Most obtained by digging wells

  4. The Water Cycle • Water is the only substance on Earth that occurs naturally as a solid, a liquid, and a gas, or water vapor. • The water cycle is the movement of water from Earth’s surface to the atmosphere and back ; it is driven by the sun’s energy. • Evaporation—water turns from liquid to gas. • Condensation—the rising gas cools and condenses, or changes from a vapor into tiny liquid droplets, to form clouds. • Precipitation—if the droplets in clouds become heavy enough, they fall back to Earth as rain, snow, sleet, or hail. • Runoff—excess water that isn’t absorbed as groundwater flows over land and collects in streams, rivers, and oceans.

  6. Importance of water • Lack of available freshwater, which can be caused by droughts or overuse • Contaminated, or polluted, water can harm humans, plants, and animals. • Flooding can damage property and threaten lives. • Provides us with food to eat • Important source of energy • Provides us with recreation, including swimming, fishing, surfing, and sailing

  7. Exit Slip • Post-it: What’s the MOST important item you learned today and what is one question you still have. • Have a great remainder of the day.
