4. Earth: The Blue Planet : Vocabulary Part I 1) ocean: a large body of salt water. 2) fresh water: water that contains little or no dissolved salt (about 1% of earth’s water. 3) evaporation: the process of liquid turning into gas. Page 2 Earth’s Water: Lesson 1

5. Earth: The Blue Planet : Vocabulary Part II 4) water vapor: is when water turns from liquid to gas in the evaporation process. 5) ice sheet: a huge slab of ice and snow that covers a very large area of LAND. 6) glacier: a large body of ice that moves slowly over land through water.

7. Earth: The Blue Planet : Main Ideas 1)How much of Earth’s surface is covered by water and where do we find it? (pg. 180-181)  a) 71% and most of it is found in our 5 oceans. 2) How much of Earth’s water is fresh water?  a) 1% Page 5 Earth’s Water: Lesson 1

8. 2) What makes the ocean’s salty? (pg. 182- 183)  a) The addition of salt is a continual process and salt does not evaporate with water. Quick Check (pg. 183) -Summarize: What are three ways that salts enter the ocean’s?  a) Water in the ocean is salty because salt is transported in streams and rivers, waves dissolve salt when they wash up on beaches and underwater volcanoes add salt as well.
