1Bellringer: 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 tomorrowFri- Quiz on Water (vocab and notes)
2Weather – condition of the atmosphere at a particular time and place. Atmosphere – mixture of the gases that surrounds the Earth.Altitude – height of an object above the Earth.Troposphere – layer with 90% of the atmosphere’s total mass; layer where we live; (gets colder as you go higher)Stratosphere – layer with the ozone layer; (gets warmer as you go higher)Mesosphere – coldest layer of the atmosphere; (gets colder as you go higher)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 ozone10. Wind – moving air11. Coriolis effect – Earth’s rotation causes objects (wind) to follow a curved path12. Trade wind – winds that blow from 30 degrees lattitude to the equator13. Westerlies – winds that blow from 30 to 60 degrees lattitude14. Polar easterlies – winds that extend from 60 degrees lattitude
4Water on Earth There are two types of water: Fresh water & Salt waterFresh water is water that is not saltyMost rivers and lakes are fresh waterSalt water is water that contains dissolved salts and other mineralsWater in the ocean is salt waterHumans and most land animals can not survive by drinking salt water
5Earth’s Water Most of water on Earth is in the ocean 97% is salt waterOnly 3% is fresh water
7Water Flows and Collects Water collects in rivers and streamsRiver SystemsTributary- a stream that flows into a lake or into a larger stream
8Water Flows and Collects River systems are divided into watershedsWatershed (drainage basin)Land that is drained by a water systemlargest watershed is the Mississippi River watershed
9Stages of a River Youthful Rivers Mature Rivers Old Rivers Rejuvenated Rivers
10Stream & River Deposits Deposition is the process where material is dropped or laid downRock and soil deposited by streams are called sediment
11Delta River deposits its load in a fan-shaped pattern A river empties into a large body of waterExp: Mississippi River flows into the Gulf of Mexico
12Deposition on Land Alluvial fans Floodplains Fan-shaped deposits that form on dry landFloodplainsArea along a river that forms from sediments deposited when a river overflowsRich farming areas
13Prevent Flooding Dam Levee Barrier to redirect the flow of water Buildup to control flooding
14Conserve Water Only 3% of Earth’s water is drinkable Most of the fresh water is frozen in icecaps and glaciersHow do we misuse our water?How can we conserve water?
15Pollution 2 types of Pollution: Point-Source Pollution Pollution that comes from a specific siteCan mostly be controlledExp: a leak from a sewer pipeNonpoint-source PollutionPollution that comes from many sourcesDifficult to controlExp: street gutters, fertilizers and soil
17Earth’s Ocean What is the largest ocean? Pacific Ocean What is the smallest ocean? Artic OceanOcean water is salty.Ocean water is not safe to drink.
18Bellringer: 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.Prepare for a textbook scavenger hunt.
19Chapter 13- Scavenger Hunt Write the questions. Which is the largest ocean?Which is the smallest ocean?What percentage of earth’s 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.
22Take out a sheet of paper and copy the standard Take out a sheet of paper and copy the standard. Head you paper properly.S6E3- Students will recognize the importance of water in earth processes.
23Bellinger: Take out a sheet of paper and copy the standard Bellinger: Take out a sheet of paper and copy the standard. Head your paper properly.S6E3- Students will recognize the importance of water in earth processes.Write down 10 facts about the ocean. You may use your textbook.You have 15 minutes to complete the assignment. It will be collected and graded!
24CRCT Practice Assignment Bellringer: Take out a sheet of paper and copy the standard. Head your paper properly.S6E3- Students will recognize the importance of water in earth processes.CRCT Practice AssignmentRead pagesAnswer the questions on pages*Think It Through question on page 88*Test Practice questions (1-3) on page 89Write the questions and the correct answer.
25Magic School Bus Assignment Prepare to see a Magic School Bus video on the water cycle.Take at least 15 video notes. You will share your notes at end of the video.
34Bellringer Assignment: Answer Chapter Review questions 1-15 on page 292.Define the terms in questions 1-6Only 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!
35Short 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.
36Technology 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.
37The two major regions of the ocean floor are the continental margin and the deep-ocean basin. They are all sections of the continental margin.
38Living resources- fish and seaweed Nonliving resources- oil and minerals
39Short Answers to Study Guide Nonpoint-source pollution comes from many sources (run-off, gutters, fertilizers, etc.)Point-source pollution comes from
40WatershedsWatersheds are separated from each other by an area of higher ground called a divideExp: Continental Divide
41Stream Erosion What factors cause a stream to flow faster? Gradient- change in elevationDischarge- amount of water carriedLoad- materials carried by a stream
