1 Bellringer: Take out a pencil and copy your HW for the week. S6E3- Students will recognize the importance of water in earth processes. Wed- Complete worksheet and answer review questions. Thur- Study for the quiz tomorrow Fri- Quiz on Water (vocab and notes)

2 1.Weather – condition of the atmosphere at a particular time and place. 2.Atmosphere – mixture of the gases that surrounds the Earth. 3.Altitude – height of an object above the Earth. 4.Troposphere – layer with 90% of the atmospheres total mass; layer where we live; (gets colder as you go higher) 5.Stratosphere – layer with the ozone layer; (gets warmer as you go higher) 6.Mesosphere – coldest layer of the atmosphere; (gets colder as you go higher) 7.Thermosphere – greatest heat, but not hot due to distance between air particles

3 ( gets warmer as you go higher) 8. Conduction – transfer of thermal energy by direct contact. 9. Greenhouse effect – Earth is getting warmer due to pollution and loss of ozone 10. Wind – moving air 11. Coriolis effect – Earths rotation causes objects (wind) to follow a curved path 12. Trade wind – winds that blow from 30 degrees lattitude to the equator 13. Westerlies – winds that blow from 30 to 60 degrees lattitude 14. Polar easterlies – winds that extend from 60 degrees lattitude

4 Water on Earth There are two types of water: There are two types of water: Fresh water & Salt water Fresh water & Salt water Fresh water is water that is not salty Fresh water is water that is not salty Most rivers and lakes are fresh water Most rivers and lakes are fresh water Salt water is water that contains dissolved salts and other minerals Salt water is water that contains dissolved salts and other minerals Water in the ocean is salt water Water in the ocean is salt water Humans and most land animals can not survive by drinking salt water Humans and most land animals can not survive by drinking salt water

5 Earths Water Most of water on Earth is in the ocean Most of water on Earth is in the ocean 97% is salt water 97% is salt water Only 3% is fresh water Only 3% is fresh water

6 Water Cycle

7 Water Flows and Collects Water collects in rivers and streams Water collects in rivers and streams River Systems River Systems Tributary- a stream that flows into a lake or into a larger stream Tributary- a stream that flows into a lake or into a larger stream

8 Water Flows and Collects River systems are divided into watersheds River systems are divided into watersheds Watershed (drainage basin) Watershed (drainage basin) Land that is drained by a water system Land that is drained by a water system largest watershed is the Mississippi River watershed largest watershed is the Mississippi River watershed

9 Stages of a River Youthful Rivers Youthful Rivers Mature Rivers Mature Rivers Old Rivers Old Rivers Rejuvenated Rivers Rejuvenated Rivers

10 Stream & River Deposits Deposition is the process where material is dropped or laid down Deposition is the process where material is dropped or laid down Rock and soil deposited by streams are called sediment Rock and soil deposited by streams are called sediment

11 Delta River deposits its load in a fan-shaped pattern River deposits its load in a fan-shaped pattern A river empties into a large body of water A river empties into a large body of water Exp: Mississippi River flows into the Gulf of Mexico Exp: Mississippi River flows into the Gulf of Mexico

12 Deposition on Land Alluvial fans Alluvial fans Fan-shaped deposits that form on dry land Fan-shaped deposits that form on dry land Floodplains Floodplains Area along a river that forms from sediments deposited when a river overflows Rich farming areas

13 Prevent Flooding Dam Dam Barrier to redirect the flow of water Barrier to redirect the flow of water Levee Levee Buildup to control flooding Buildup to control flooding

14 Conserve Water Only 3% of Earths water is drinkable Only 3% of Earths water is drinkable Most of the fresh water is frozen in icecaps and glaciers Most of the fresh water is frozen in icecaps and glaciers How do we misuse our water? How do we misuse our water? How can we conserve water? How can we conserve water?

15 Pollution 2 types of Pollution: 2 types of Pollution: Point-Source Pollution Point-Source Pollution Pollution that comes from a specific sitePollution that comes from a specific site Can mostly be controlled Can mostly be controlled Exp: a leak from a sewer pipe Exp: a leak from a sewer pipe Nonpoint-source Pollution Nonpoint-source Pollution Pollution that comes from many sourcesPollution that comes from many sources Difficult to control Difficult to control Exp: street gutters, fertilizers and soil Exp: street gutters, fertilizers and soil

18 Bellringer: Take out a sheet of paper, your science textbook and a pencil. Head your paper and copy the standard. S6E3- Students will recognize the importance of water in earth processes. S6E3- Students will recognize the importance of water in earth processes. Prepare for a textbook scavenger hunt. Prepare for a textbook scavenger hunt.

19 Chapter 13- Scavenger Hunt Write the questions Which is the largest ocean? Which is the smallest ocean? What percentage of earths surface is covered with water? What divides the oceans? What percentage of ocean water is chlorine and sodium? List the three main temperature zones of the ocean List three structures that can be found on the ocean floor.

20 Water Underground

21 How did the oceans form?

34 Bellringer Assignment: Answer Chapter Review questions on page 292. Define the terms in questions 1-6 Only write the correct answer choice along with the alphabet. You do not have to write the questions. You have 30 minutes to complete the assignment. This will be graded!

35 Short Answers to Review Questions Coastal water in hotter, drier climate typically has higher salinity because less freshwater runs into the ocean in drier areas. Heat increases the evaporation rate.

36 Technology used to study the ocean floor includes sonar and research vessels such as Alvin and Deep Flight. Sonar, research vessels and satellites are used to study the ocean floor.

37 The two major regions of the ocean floor are the continental margin and the deep-ocean basin. They are all sections of the continental margin.

38 Living resources- fish and seaweed Nonliving resources- oil and minerals

39 Short Answers to Study Guide Nonpoint-source pollution comes from many sources (run- off, gutters, fertilizers, etc.) Point-source pollution comes from

40 Watersheds Watersheds are separated from each other by an area of higher ground called a divide Watersheds are separated from each other by an area of higher ground called a divide Exp: Continental Divide Exp: Continental Divide

41 Stream Erosion What factors cause a stream to flow faster? What factors cause a stream to flow faster? Gradient- change in elevation Gradient- change in elevation Discharge- amount of water carried Discharge- amount of water carried Load- materials carried by a stream Load- materials carried by a stream
