Geology

*There are no snacks or coffee available this morning. Odd, that.*

Please don't forget to sign the roll sheet.

Today, we will begin discussing crustal deformation.

I refer you to the first figure in your handouts. The topographic map illustrated in Figure 10l-1 suggests that the Earth's surface has been deformed. This deformation is the result of forces that are strong enough to move ocean sediments to an eleveation many thousands meters above sea level. In previous lectures, we have discovered that this displacement of rock can be caused by tectonic plate movement and subduction, volcanic activity, and intrusive igneous activity.

Deformation of rock involves changes in the shape and/or volume of these substances. Changes in shape and volume occur when stress and strain causes rock to buckle and fracture or crumple into folds. A fold can be defined as a bend in rock that is the response to compressional forces. Folds are most visible in rocks that contain layering. For plastic deformation of rock to occur a number of conditions must be met, including:

*The rock material must have the ability to deform under pressure and heat.
*The higher the temperature of the rock the more plastic it becomes.
*Pressure must not exceed the internal strength of the rock. If it does, fracturing occurs.
*Deformation must be applied slowly.

Phoebe signs in, but her hands are shaking. She takes her usual seat and tries to concentrate on Professor Sidle's lecture, but she can't seem to focus and she is fighting tears.

[chasingangela]

Angela takes her usual seat beside Phoebe, who looks as bad as she feels. She scribbles a note.

You heard about Kitty? -- A.

[sensethevisions]

Phoebe looks at it and then nods.

I was actually told about it early yesterday morning. -- P

[chasingangela]

I heard last night. It's horrible.

Who could do something like that? Unbelievable. --A.

[sensethevisions]

Phoebe shakes her head.

I don't know, but I am damn well going to find out! She was a good friend, not to mention a roommate. -- P

[chasingangela]

Angela nods.

I only knew her a little, but she was so sweet. I trust you. Let me know if I can help. --A.

[sensethevisions]

Phoebe gives a faint smile.

I trust you, too. Kitty and Lockheed have treated me like family since I've been here and I won't let someone get away with taking Kitty from those that loved her. -- P

[chasingangela]

Thank you for trying. Just don't get yourself hurt, okay? --A.

*Walking past while lecturing, she briefly squeezes one of Phoebe's shoulders.*

[sensethevisions]

Phoebe looks up and tries to smile at her, but she feels tears again and quickly looks down.

Draco signs in and goes to grab a cup of coffee but finds that there isn't any there. He gives Ms. Sidle a weird look before going to his desk. He begins to take notes.

Rory takes a seat beside Draco, looking drawn and paler than usual.

[pure-blooddraco.livejournal.com]

Draco tries to give Rory a reassuring smile.

"Hey is everything alright? I mean-of course it isn't, sorry." he says

[auroryborealis.livejournal.com]

Rory glances over at him, and attempts a smile.

"No, nothing's all right. But I don't think I'm technically supposed to talk about it."

[pure-blooddraco.livejournal.com]

"It's probably for the best that nobody talks about it. You know how rumors spread." he says "But I'm sure that they'll get to the bottom of this and everyone can rest easier."

[auroryborealis.livejournal.com]

Rory frowns.

"Do you know, then? About what happened? I didn't think any students aside from me and the security officers and few others knew."

[pure-blooddraco.livejournal.com]

"News spreads fast around here." he said "Hence it being best that nobody talked about it. And look at everybody, something is obviously wrong, the school isn't exactly trying to keep it hush hush."

[auroryborealis.livejournal.com]

Rory looked at him, biting her lip. "I wish they'd just make an announcement, then. Better that everyone know what really happened rather than speculate and get the rumor mill going."

[pure-blooddraco.livejournal.com]

"Exactly." says Draco. He stops himself from breathing a huge sigh of relief.

[auroryborealis.livejournal.com]

"I mean, I was there...so people keep asking me what happened," she said, staring at her hands.

[pure-blooddraco.livejournal.com]

"That's horrible. I'm sure the administration will make an announcement and everyone will stop asking. It's really not fair for them to bother you about this. It's pretty traumatizing." he said "Back home my people are at war with each other. I've never had anything like...that happen to me personally but a lot of my schoolmates have."

A small note lands on Rory's desk.

It reads:
Not too good with the words and feelings, but I can listen any time. --H.

Han signs in and takes notes, sipping occasionally at the oddly shaped mug of kaf he brught with him.

Rose wanders into class, signs in and begins to take notes.

[bridge-carson.livejournal.com]

Bridge signs in and takes notes on the lecture, the emotions in the room so palpable that he can feel them without even consciously activating his powers.

[miss-thomasina.livejournal.com]

Thomasina signs her name to the class roster, takes her usual seat and opens her exercise book to begin taking notes. She is still more than a little amazed by the idea that the earth is not as solid and unmoving beneath her feet as it might feel.

Lee signs in and takes notes, mind wandering every so often as he scribbles down more emo poetry.

[conathon.livejournal.com]

Sawyer comes into class and takes his normal seat near the back, he's taking notes..or something.

[teen-twin.livejournal.com]

Connor signs in, notes the lack of coffee with a grumble, and takes his heat. He has gum in his pocket, he pops a piece in his mouth hoping that will keep him awake.
