The document discusses the water cycle and the transportation of water around the world. It explains that water makes up 60-70% of the human body and is essential for life. It also describes how water moves from the sky to the ground, collecting in rivers, lakes, and underground sources, before evaporating again into the atmosphere to repeat the cycle. Fresh water sources include glaciers, groundwater aquifers, and surface water features like lakes and rivers.

2. Water: A World Traveler Water is transported all over the world Many organisms thrive with water Bacteria: tiny one-celled organisms Fungi

3. Water: A World Traveler The Human Body: Our bodies are 60%-70% water Losing 2% of water will make you thirsty Lose 10% and your body will die

4. Water: A World Traveler Water= main ingredient of life Water in Sky: Water is found in lower troposphere Water in World: Salt Water= contains 3.5% salt Fresh Water= Low salt content

5. Water: A World Traveler Fresh Water 75% fresh water is in glaciers Water Underground: Most water flows to the water table and aquifers Ground water is main source of water for half world’s population

6. Water: A World Traveler Surface-Water Lakes Swamp River Liquid Miner Limestone= soft rock that can have rivers running through it

7. Water: A World Traveler Journey to the Sea: Water seeks the lowest level Water collects: Rills- tiny channels Brooks & Streams- medium water Rivers- large areas Tributaries- rivers that lead to the sea

8. Water: A World Traveler Drainage Basin- The area where all the water leads to Divide- high land separating one drainage basin from another Great Divide: Raindrops on one-side go one way Raindrops on other-side go one way

9. Water: A World Traveler Water: Hydrosphere: the water that is found in the ocean, land, and atomsphere Airborn Water: Rain

10. Water: A World Traveler Water Cycle: Evaporation- transferring of molecules from liquid to gas Water Vapor: gaseous water in the atmosphere Temperature- speeds up evaporation

11. Water: A World Traveler Condensation: Water vapor cools and becomes water droplets Precipitation: Any form of water that falls from the clouds

12. Water: A World Traveler Water Cycle: Water Evaporates Water Condenses into clouds Water falls as precipitation This movement of water is called the water cycle.
