12th grade – APRIL 18, 2016 *all late/makeup work must be completed before April 29 for credit.Math tests are MONDAYSScience tests are FRIDAYSQuizzes are any days TESTS may need to be moved if we are not quite ready…but that is the exception.You need to check the weebly every night BEFORE you start your HW!!!!!

REVIEW QUESTIONS 1. How do P-waves travel through Earth’s interior?

P-waves are longitudinal; they compress and expand rock as they move through it. P-waves can travel through any type of material—solid, liquid, or gas. They are the fastest of all seismic waves and the first to register on a seismograph.

2. How do S-waves travel through Earth’s interior?S-waves are transverse—they vibrate the particles of their medium up and down and side-to-side. S-waves can travel only through solids. They are the second to register on a seismograph.

3. Can S-waves travel through liquids?No. S-waves can travel only through solids.

4. Name the two types of surface waves and describe the motion of each.Rayleigh waves and Love waves. Rayleigh waves move in an up-and-down, rolling motion. Love waves move in a side-to-side, whip like motion. Both of these surface-waves travel at lower speeds than P- and S-waves and so are the last to register on a seismograph.

5. What was Andrija Mohorovicic’s major contribution to Earth science?Mohorovicic discovered the crust-mantle boundary.

6. How did seismic waves contribute to the discovery of Earth’s core?Both P- and S-waves are strongly refracted at the core-mantle boundary, causing a wave shadow. The reflection and refraction of P-waves through the core identified the solid inner core.

7. What is the evidence that Earth’s inner core is solid?The reflection and refraction of P-waves through the core identified the solid inner core.

8. What is the evidence that Earth’s outer core is liquid?S-waves cannot travel through liquids. The presence of the S-wave shadow—no S-waves are found in this zone—indicates that the outer core is liquid.

9. In what ways are the asthenosphere and the lithosphere different from each other?The upper mantle, extending from the crust-mantle boundary down to a depth of about 700 kilometers, has two zones: The lower zone is the plastic-like asthenosphere, which flows due to convection. The upper zone (above the asthenosphere) is the lithosphere. The lithosphere includes the entire crust and the uppermost part of the mantle. It is relatively rigid and brittle and resists deformation. The mobile lithosphere is, in a sense, floating on top of the asthenosphere.

10. How does continental crust differ from oceanic crust?They differ in density, composition, and thickness. Oceanic crust is thin and compact (about 10 km thick) and composed of dense basaltic rocks. Continental crust is between 20 and 60 kilometers thick and composed of less dense granitic rocks.

I HAVE SOME HW 4 U 4/18 HW = CH 26 RQ 11-20 FYI = RATS DUE THURS @ 8 AM VIA EMAIL TO ME BY 8 AM!!!JUST SEND ME A LIST OF ANSWERS AS IN A,B,C,D,ETC.DOES NOT HAVE TO BE IN A DOC – IT CAN BE IN THE BODY OF THE EMAIL…

PreCalculus

Glogs due Monday…ELSE = 0…BEGINNING MARCH 14, 2016.

HW WAS: 2 WS4/12=NAME+NBQUIZ+P.464+DATE ANSWERS ONLY TO 3-14 – GO.

Remember – FOR ALL CLASSES – to note every 30 minutes!!!option 1 = do 30 min on each class hw - start with math - then you must move on to another class…then come back if you need to…option 2 = there is no option 2.YOU NEED TO SET A TIMER FOR 30 MIN.

Page 483 # 1-10 … use desmos !!!

MONDAY = TEST DAY

CSC, COT, SEC ON YOUR CALC:

CSC = 1/SINCOT = 1/TANSEC = 1/COSYOU MUST KNOW HOW TO DO THIS!SO … PUT IN “1” THEN “÷” THEN “SIN 31.67” THEN ENTER…OR…use the x-1 key …1=on2=clear3=degree mode

p.464

1. 2. 3. 4. 7/√655. 6. 7/4 7. 8. √65/49. 10. h ≈ 20.9811. 3 answers12. m<A = 55◦ ; b ≈ 14.6 ; c ≈ 8.413. 3 answers14. m<A = 45◦ ; m<C = 45◦ ; b = 3√2 ≈ 4.24

so

19 answers so = -5 each

Ok picture from the board:

Homework Precalc = calc = p.465 # 31-42HW 4/18 = DO P.483 1-10 WELL AND PREPARE TO TURN IN TOMORROW = NICELY PRINTED AND TAPED OR HAND DONE.Hw changed to:Page 483 # 1-10 … use desmos !!!I have left in 2 examples from your hw – you must do the rest and either print and tape into your spiral or email to me before 8 am Friday for full credit…

precalc hw = do/redo last night's hwyou must print out your graphsor email to me in a word doc before 8 am Friday.

======================================OTHER 12 th grade HW IS LISTED BELOW: 6 FLAGS FORM = Michael

LIT = LONE RANGER & TONTO = READ CH & GIVE RESPONSE ON WEEBLY TONIGHT

US HISTORY = read ch 23

RELIGION = pray & rice box

ECON = STUDY ch 3 weebly notes & VOCAB … test coming 4/14

Spanish – SPANISH AUTHOR PROJECT = ½ OF FINAL EXAM

SEE ABOVE FILE FOR MATH AND SCIENCE!!!

MATEO SAYS: DO ALL OF YOUR HW AND DO IT WELL!!!
