eescilsm: hi there
Bhy65432: i was wondering if there was anywhere on the site that i could find a visual of the ocean to continent thing???
eescilsm: yep - find the graphics page
Bhy65432: okie ill check there
Bhy65432: thank you :-)
eescilsm: ok

An AOL IM "conversation":

Bnmvcxz: hey, i had a question about the mineral hardeness section on the test
eescilsm: ok
Bnmvcxz: it says, identify a mineral by the given mineral, does that mean that you are going to give us the name of the mineral
Bnmvcxz: or just the actual mineral, physically
eescilsm: i ask a question about using the hardness scale
Bnmvcxz: oh, almost as if how to test for hardeness
eescilsm: yep
Bnmvcxz: i know what you mean now, thank you
eescilsm: ok
eescilsm: anything else?
(no response)

Hgfdsa: hey, where's that list of things that u need to know
Hgfdsa : like where on the website
eescilsm: did you look for it on the main web page?
Hgfdsa : yeah, what's it called
eescilsm: the Learning Objectives in the Internal Earth P+P Section
Hgfdsa : k thanks
eescilsm: did you find it?

In response to the message below:

I won't ask what step number out of 20, but you should
know what happens before and after any of the steps.
What is important is the cause and effect
relationships. 

If you have memorized that whole list, you probably
know the sequence better than I do!

Ghjklasdf: omg!!!!! thank god ur on!!!!!!
eescilsm: its nice to be needed!
Ghjklasdf: lol
eescilsm: who's this?
Ghjklasdf: ***
Ghjklasdf: ***
eescilsm: hi there
Ghjklasdf: ok i don't get how rocks change their minerals or something
eescilsm: the igneous rocks don't change minerals much, one type of rock forms, then a different kind will form after it
Ghjklasdf: ooo so heat and pressure change it and then another diff. rock forms??
eescilsm: are you talking about igneous or metamorphic rocks?
Ghjklasdf: i dont' know what's the difference
Ghjklasdf: are igneous rocks the ones with the magma?
eescilsm: igneous forms from molten rock, metamorphic rocks start as any kind, then change because of heat and pressure without melting
Ghjklasdf: ooooo ok
eescilsm: so which kind are you talking about?
Ghjklasdf: igneous
Ghjklasdf: but igneous wouldn't be able to change would they??? or does it depend on how fast they cool
eescilsm: one kind of rock, like gabbro solidifies on the bottom of the magma, then after that the magma that is left over will form the next kind of rock in the sequence, either diorite or andesite
Ghjklasdf: how long is the essay going to be?
Ghjklasdf: oooo ok
eescilsm: enough to answer the question
Ghjklasdf: ok
Ghjklasdf: bye
eescilsm: i hope this helped
Ghjklasdf: it did
eescilsm: good - see you tomorrow
Ghjklasdf: yup

An AOL IM conversation

Rtyuiop: Hi mr. mitchell :) this is Rtyuiop 

eescilsm: hi

Rtyuiop: i have a question on one of the worksheets u gave us

eescilsm: go ahead

Rtyuiop: ok its a worksheet u gave us recently, its has the classification of Igneous rocks on it

eescilsm: yep

Rtyuiop: remember how we had to draw lines vertically on it- i dont really understand how we could tell what the rock had in it by that

eescilsm: the mineral areas above the rock names tell what minerals are in those rocks

Rtyuiop: so pyroxene is in basalt and gabbro?

eescilsm: yes, but it is also found in...?

Rtyuiop: um??

eescilsm: what other rocks are under the other part of the area marked pyroxene?

Rtyuiop: i dont know thats the part i dont understand i dont see any other rocks??

eescilsm: although the word pyroxene is directly over gabbro and basalt, there are curved lines over it that mark its "area"

Rtyuiop: ok so?

eescilsm: some of the pyroxene "area" extends to the right over peridodite, some of the "area" extends to the left over diorite/andesite

Rtyuiop: ok but the line keeps going

eescilsm: over what rocks?

Rtyuiop: all of them

eescilsm: but the area gets thinner and thinner?

Rtyuiop: how?

eescilsm: the area gets thinner vertically

eescilsm: because those rocks do not have much pyroxene in them

Rtyuiop: i still dont see how they get thinner

eescilsm: how much pyroxene area is over granite compared to the thickness of the quartz area?

Rtyuiop: wait where the arrow line we had to draw is?

eescilsm: i'm not sure

Rtyuiop: how do u find the area?

eescilsm: how much space does it take up vertically?

Rtyuiop: ????? :(

eescilsm: give me a minute to find the text book and i will give you another example...

Rtyuiop: ok

eescilsm: i can't find it - maybe the other diagram would be easier to use

Rtyuiop: ok

eescilsm: is diorite-andesite in the middle of a color zone?

Rtyuiop: its white

eescilsm: what minerals are in that white area or touching it?

Rtyuiop: what?

eescilsm: are you loking at the other diagram?

Rtyuiop: on top of it?

eescilsm: at the top of the handout i gave out

Rtyuiop: ok

Rtyuiop: thw white part is olivine

Rtyuiop: wait um peridotite gabbro??

eescilsm: where is diorite-andesite?

Rtyuiop: like in the middle of crystillizing

Rtyuiop: a gray part

eescilsm: what mineral names are touching that same shade of gray?

Rtyuiop: where?

eescilsm: on the left part of that diagram

Rtyuiop: plagioclase

eescilsm: are pyroxene, sodium feldspar (plagiocalse), amphibole next to or in the same color as the words diorite-andesite?

eescilsm: by the way, my son just found our text, if you want to work with that diagram

Rtyuiop: sodim feldspar is

Rtyuiop: what page?

eescilsm: 110

Rtyuiop: ok

Rtyuiop: ok what do i do now?

eescilsm: thats the diagram we were working with before?

Rtyuiop: yes

eescilsm: above andesite-diorite, do you see how thick the p-feldspar zone is compared to quartz, pyroxene, amphibole etc?

Rtyuiop: i dont see how the pyroxene is thincker than feldspar

eescilsm: above diorite-andesite, proxene is not thicker than feldspar

Rtyuiop: but proxene isnt in that column

Rtyuiop: vertically it isnt

eescilsm: yes it is - the pyroxene "zone" is all the area from the word pyroxene out in all directions to the solid lines

Rtyuiop: oooooo ok

eescilsm: the pyroxene "zone" is not just between the dotted lines

Rtyuiop: ok i get it know

eescilsm: really? you sure?

Rtyuiop: well the line part

Rtyuiop: ok how do i find out the rock thing again

eescilsm: if you had a rock that was mostly (over half) pyroxene, a little bit olivine, and a little p-feldspar, but no amphibole, with big crystals, what is it?

Rtyuiop: i have no clue

Rtyuiop: basalt or gabbro?

eescilsm: YES! which one?

Rtyuiop: umm i dont know how to tell which one

Rtyuiop: they both have those

eescilsm: big crystals means it cooled slowly

Rtyuiop: ok how do i tell if it cooled slowly or not

Rtyuiop: is it by the texture?

eescilsm: if it cooled slowly, it will have big crystals, and that is described as being coarse grained

Rtyuiop: gabbro?

eescilsm: YOU GET AN A!

Rtyuiop: yah :) lol

Rtyuiop: can u give me another one?

eescilsm: how did you know it wasn't peridotite?

Rtyuiop: becuz it didnt have feldspar in it

Rtyuiop: no waiy

eescilsm: it did - it had plagioclase feldspar

Rtyuiop: wait*

Rtyuiop: yah

Rtyuiop: it didnt have over half of pyroxene in it

eescilsm: great

Rtyuiop: i got it right?

eescilsm: yep

Rtyuiop: ok

Rtyuiop: will we have this chart on the test?

eescilsm: oooohhhhh yea

Rtyuiop: ok :)

Rtyuiop: give me one more please

eescilsm: even a nasty, rotten person like me wouldn't make you memorize this stuff

Rtyuiop: lol

Rtyuiop: hey i like ur info hehe

eescilsm: what rocks would have formed before a rock containing over 50% potassium feldspar?

eescilsm: in order please

Rtyuiop: ut o

eescilsm: ?

Rtyuiop: do i use the chart for this?

eescilsm: I certainly would

Rtyuiop: ok

Rtyuiop: i dont understand how u would find that out

eescilsm: what rock is it?

Rtyuiop: that has over 50% feldspar?

eescilsm: over 50% potassium feldspar

Rtyuiop: ok

Rtyuiop: rhyolite

eescilsm: or?

Rtyuiop: granite

eescilsm: yes, and what rocks formed from the magma before those?

Rtyuiop: diorite and andesite

eescilsm: if the magma reached the surface and flowed as lava, cooling to an extrusive fine grained rock, then no other rocks could have formed from that magma - the sequence stops dead

Rtyuiop: hey trick question

eescilsm: andesite forms INSTEAD of diorite

Rtyuiop: yeah i know that

Rtyuiop: andesite forms after gabbro right?

eescilsm: andesite COULD form after gabbro, but if it did, no rocks could form after it

eescilsm: so what was the first rock?

Rtyuiop: yes because andesite cant for into anything

Rtyuiop: form*

Rtyuiop: the first rock to start the sequence?

eescilsm: remember these rocks do not turn into something else, one rock will form then the next in the sequence on top of the first ones

eescilsm: what rock will form first?

Rtyuiop: can u be more specific witht he question

eescilsm: as a magma plume begins to rise through continental crust, what is the first igneous rock to solidify?

Rtyuiop: peridotite

eescilsm: yes - then?

Rtyuiop: cuz its the frist to cyrstalize?

eescilsm: then?

Rtyuiop: gabbro

eescilsm: then?

Rtyuiop: diorite

eescilsm: then?

Rtyuiop: granite

eescilsm: or?

Rtyuiop: or

Rtyuiop: rhyolite

eescilsm: so...

Rtyuiop: so??

eescilsm: what rocks would have formed before a rock containing over 50% potassium feldspar?

Rtyuiop: peridotie, gabbro and diorite]

eescilsm: ANOTHER A!

Rtyuiop: yah

Rtyuiop: ok well i got to go now thank you so much i finally inderstand it hehe :)

eescilsm: how we doing?

Rtyuiop: good

eescilsm: i hope you understand the rest of the test as well

Rtyuiop: lol i hope so too

Rtyuiop: see u tomorrow byebye

eescilsm: goodnight

Rtyuiop: bye
