Question

Guys I have searched every site and they all say the same answer but it is incorrect. PLEASE HELP! I will give a MEDAL, TESTIMONIAL, and FAN.

Answer 1

Which of the following is a technique used in relative dating?

Beta decay

Index fossil correlation

Isotope ratios

Radiocarbon dating

Answer 2

beta decay is radioactive decay in which an electron is emitted.
I believe that it is Radiocarbon dating

Answer 3

@BassCatcher15 what answer choice did they say it is wrong?

Answer 4

I submitted this exam and had to reset it a little while ago. They're saying radiocarbon dating is wrong

Answer 5

really? does it give you the right answer?

Answer 6

Nope

Answer 7

oh ok. my next answer would be Index fossil correlation

Answer 8

I'm pretty sure the answer is Isotope ratios..

Answer 9

Beta decay, isotope ratios and radiocarbon dating are all radiometric dating methods.

Answer 10

Ohhhh great.... Lol So yall are saying it could be a or b, or maybe d or c? XD

Answer 11

@BassCatcher15 lol xD

Answer 12

Oh sorry I got Radiometric and Relative dating mixed up oops

Answer 13

@lyssfountain it is okay :)

Answer 14

So yall are pretty confident that its index fossil correlation? @lyssfountain PM me back. Lol

Answer 15

Yeah I agree with @superhelp101 that it's index fossil correlation

Answer 16

yes!

Answer 17

Thanks guys!!! I really appreciate it

Answer 18

@superhelp101 @lyssfountain

A sample of rock is found to contain 100 grams of a parent isotope. How many grams of the parent isotope will remain after two half-lives?

100

75

50

25

Answer 19

25 grams. It was halved twice so 100/2= 50 and 50/2=25

Answer 20

Okay thats what I though. Thanks!

Answer 21

The following images represent four separate events that happened to this section of rock, though not necessarily in the order shown below. Which image represents the event that happened next to last?

All five strata are curved like waves, and the left-hand section of rock is elevated higher than the right-hand section of rock.

All five strata are curved like waves, and the left-hand section of rock has completely folded on top of the right-hand section of rock.

All five strata are curved like waves.

All five strata are curved like waves, and the left-hand section of rock has begun to fold over the right-hand section of rock.

Answer 22

I believe it is the last
" All five strata are curved like waves, and the left-hand section of rock has begun to fold over the right-hand section of rock."

Answer 23

Thanks!!

Answer 24

Yeah, @lyssfountain should check me because i could still be wrong

Answer 25

I can't see the images :p idk why so I can't really help

Answer 26

Alright well I appreciate both of yalls help

Answer 27

I was just going from the description...

Answer 28

After two half-lives, a sample contains 10 grams of parent isotopes. How many grams of the parent isotope were present to start?

60

40

30

20


This one is 40 right?

Answer 29

Yes

Answer 30

Explain why both relative dating and absolute dating are necessary to develop the fossil record.

Answer 31

I cannot help you there.

Answer 32

@BassCatcher15 do you have any lesson materials to study for exams?

Answer 33

What do you mean @Zale101 ?

Answer 34

is this an exam?

Answer 35

It's an assessment

Answer 36

This is the last part of the assessment.

You are digging a hole in your backyard when you see a piece of fossilized bone in the dirt. How could you prove the age of the fossil? Design a procedure for determining the relative and absolute age of the bone.

Answer 37

Ok, but it looks like you need a lot to study instead of finding people to throw you off the answers. It would be a great opportunity to work those assessments by yourself and then use them for your upcoming exams :)
And if you need help, you'd just pick the most difficult question out of those and then try to find people who can explain it to you....

Answer 38

Ummm... @Zale101 This assessment is like, 54 questions. I've asked 4 or 5 that were difficult to me.

Answer 39

You would use carbon dating to prove the age of the fossil
