TODAY = 4/13 = Ch 25 RQ 1-10 = REVIEW QUESTIONS

1. How did density segregation contribute to Earth’s internal layers?

As heavy materials moved toward Earth’s center and lighter materials moved toward the surface, Earth’s interior became layered according to density.

2. What is the most abundant element for Earth as a whole?

As a whole, the Earth is 33% iron.

3. What is the most abundant element in Earth’s crust? What is the second most abundant element?

Oxygen is the most abundant element in Earth’s crust (46.60 47% by mass). The second most abundant element in Earth’s crust is silicon (27.72 28% by mass).

4. What is a mineral?

A mineral is a naturally formed, inorganic, crystalline solid composed of an ordered arrangement of atoms with a specific chemical composition.

5. What physical properties are used to identify minerals?

The physical properties used to identify minerals include crystal form, hardness, cleavage and fracture, color, density, luster and streak.

6. Most mineral samples do not display their crystal forms. Why not?

Well-shaped crystals are rare in nature because minerals typically grow in cramped spaces.

7. Why is color not always the best way to identify a mineral?

Chemical impurities affect color. Many minerals come in multiple colors.

8. What is the difference between a silicate mineral and a nonsilicate mineral?

Silicate minerals contain both silicon and oxygen as part of their chemical composition. Minerals that do not contain these two elements are called nonsilicates.

9. What is the most abundant mineral in Earth’s crust? What is the second most abundant mineral?

Feldspars are the most common and abundant minerals. Quartz is the second most common mineral.

10. What is the process of crystallization?

Crystallization is the growth of a solid from a liquid or gas whose atoms come together with a specific chemical composition and crystalline arrangement. Beginning with the formation of a single microscopic crystal, the crystal grows as more and more atoms bond to the crystal faces.

RQ 11-20

11. Name the three major types of rocks and describe the conditions of their origin.Igneous, sedimentary, and metamorphic. Igneous—formed from the cooling and crystallization of magma. Sedimentary—formed from weathered material carried by water, wind, or ice. Metamorphic—formed from preexisting rocks transformed by high temperature, high pressure, or both—without melting.

12. What are the most common igneous rocks, and where do they generally occur?On the continents, the most common igneous rocks are granite and andesite. On the ocean floor, the most common igneous rock is basalt.

13. Where on Earth’s surface are lava flows most common?Lava flows are most common on the ocean floor.

14. What are the three major types of volcanoes?Shield volcanoes, cinder cones, and composite cones.

15. What are three common types of plutons?Dikes, sills, and batholiths.

16. How does weathering produce sediment? Distinguish between weathering and erosion.Weathering breaks down and decomposes surface rock. Erosion is the process by which weathered rock particles are removed and transported away by water, wind, or ice…GLACIERS…

17. What is a clastic sedimentary rock?A clastic sedimentary rock is composed of small fragments of preexisting rocks. Clastic sedimentary rocks are classified by particle size.

18. When water evaporates from a body of water, what type of sediment is left behind?Evaporation leads to the formation of evaporites—minerals and rocks that are precipitated when a restricted body of seawater or the water of a saline lake evaporates. (Examples of evaporites include gypsum, anhydrite, and halite.)

19. What is metamorphism? What causes it?Metamorphism occurs when pre-existing rocks undergo changes due to increased heat and pressure.

20. Distinguish between foliated and nonfoliated metamorphic rocks.Foliated rocks have a layered appearance, as in parallel flakes, or plates, of mica. Nonfoliated

metamorphic rocks do not have the aligned, platy mineral configuration.

I HAVE SOME HW 4 U 4/11/16 = 12 items from our class today … textbook ch 25 (ch 20 videos) … a sentence or two from the video/book on each one…not from anywhere else.4/12/16 = ch 25 rq 1-10 complete answers = either write the question then the answer – or – write a complete answer that restates the question…else 0 credit.

4/13/16 = ch 25 rq 11-20 complete answers ^Test is Friday = word bank not open notes so you must study the questions and answers.

4/14/16 = READ CH 25 THEN STUDY THE RQ QUESTIONS AND ANSWERS – TEST FRIDAY = WORD BANK…NOT OPEN NOTES!!!

PreCalculus

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

HW WAS: chapter 6 – do in spiral – p.464 do # 3-14 … SAW … AW. Start now…finish tonight 4/12=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.

MONDAY = TEST DAY

Page 483 # 1-10 … use desmos !!!

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.4641. 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 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…

[ 5pi/3 , 3pi]

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: Not updated Thursday 4/14/166 FLAGS FORM = MichaelLIT = LONE RANGER & TONTO = READ CH & GIVE RESPONSE ON WEEBLY TONIGHT
