Question

A rock inside a building is not likely to be affected by

mechancial weathering

chemical weathering

biological weathering

any of these

Answer 1

@Schleifspur

Answer 2

well what do you think?

Answer 3

@Schleifspur d

Answer 4

why do you think that?

Answer 5

wait i think its c because a & b can happen even if it was in a building

Answer 6

am i wrong? please correct me if I am

Answer 7

how would a and b happen inside a building? it says 'unlikely', not 'impossible', btw =)

Answer 8

its c because it's in a building and biological weathering can't happen bc it's indoors

Answer 9

I don't think it's c. think about under what conditions mechanical and chemical weathering happen usually.

Answer 10

a?

Answer 11

you're not getting my vibe (uhlala :D )

I want to know from you, if rocks undergo any weathering at all inside buildings, based on your knowledge about what you have to do to rocks to actually cause a weathering effect. if you step on a rock, is that mechanical weathering?

Answer 12

no

Answer 13

right. and why is that?

Answer 14

mechanical w is when the rocks crack and break on their own

Answer 15

and why can't you cause that by stepping on them?

Answer 16

because we cant cause that we're not that strong of a force

Answer 17

absolutely correct! because you are not heavy enough. even if you're really really fat, you can't crush stones, because THE FORCE IS TOO WEAK.

and this is the key to the answer. in a building, you have neither enough force nor extreme chemical condition to cause a or b, and there is of course no biological weathering in buildings either. the right answer, therefore, is D.

Answer 18

i was right the first time D:< lmao

Answer 19

yep ^^

Answer 20

if you had explained it like you did later, we wouldnt have had the trouble :D

Answer 21

its better that i learned why.

Answer 22

that's why you're a winner

Answer 23

and also why I never give the answer right away - except when someone else provides a false answer

Answer 24

even if you did it wouldnt be smart to take the first answer you get. can you help me with a couple more? if you have time..

Answer 25

it's past midnight in germany, and I have to get up for work early...I have time for one question, then it's bed time =)

Answer 26

How can we use rocks to determine how an area used to look in the past? <- that's the question

Answer 27

okay, good question! lemme provide a picture that maybe helps you find the answer

Answer 28

o.O that's a weird rock. i know im stupid ._. well can't rocks sometimes have fossils in them then someone can study the fossil

Answer 29

you would need to be very lucky to find a fossil in an ordinary rock, they are rare.

let's take a look at the rock befor we break it apart. it's made up of two halfs. how do you think the left half was made? what does the right half look like?

Answer 30

the right half looks like granite ._.

Answer 31

yeah, kinda...it's all mashed up stuff that comes together in this half. let's say, that these are sediments, sand, some ores, stuff like that.

now the left half. what does that look like? think about the lord of the rings.

Answer 32

its looks very smooth..

Answer 33

yeah. and it's DARK. what would you think made that?

Answer 34

a volcano

Answer 35

very good! okay. what do we know so far?

- the left half clearly states that there's a volcano of some kind nearby.
- in the right part, we find chemical compounds that are present in sand/ore. then, some huge force mashed them together, like...a glacier? maybe there's some kind of beach around....

as you see, we can use many aspects of a stone to find out something about its history and surroundings!

Answer 36

thanks sooo much! :)))

Answer 37

now, we take a look at the grand canyon. as you know, there a many kinds of rock that have different colours and make for a very nice view.

if we now think about the river down there, and we know that this rivr must've dug through all the rock....then we get the impression that there has to have been a great plain before the river came. that's another kind of getting to the problem - but you don't use only the rock to get the conclusion :-)

I'm going to bed now. good night :-)
