Geology

[equalsmcsquared.livejournal.com]

*In Geology today the students will be learning about plate tectonics.*

Good morning, *Sara says, looking around the class.* I trust you all had either a restful or eventful weekend. Hangover remedy is on the counter by the door, along with energy bars. Please sign the roll sheet before you leave.

Today, we will be discussing plate tectonics. If you will open the handouts I've passed around.

The plates consist of an outer layer of the Earth, the lithosphere, which is cool enough to behave as a more or less rigid shell. Occasionally the hot asthenosphere of the Earth finds a weak place in the lithosphere to rise buoyantly as a plume, or hotspot.
Only lithosphere has the strength and the brittle behavior to fracture in an earthquake.

The map below locates earthquakes around the globe. They are not evenly distributed; the boundaries between the plates grind against each other, producing most earthquakes. So the lines of earthquakes help define the plates...

*studious students make Ms. Sidle happy.*

Draco walks in and sits down in the back. He takes out a notebook and begins taking notes.

Rory slides into the seat next to Draco. She give a little wave before opening her own notebook and furiously scribbling what Ms. Sidle is lecturing.

Thanks sir- ma'am! ma'am! Sorry. There was a thing, last night, with my dog getting loose, and, well, not much sleep for me. Sigh.

*arrives in class, signs roll sheet. Does not look like she's paying attention.*

Something wrong, Angela? *Sara has paused the lecture while the other students dig through their notes to answer a question.

[chasingangela]

Angela looks down at her desk and shakes her head slightly.

"I just didn't get much sleep last night. It's nothing."

[equalsmcsquared.livejournal.com]

As long as you're sure. *A brief smile before resuming her talk.*

[sensethevisions]

Phoebe looks at her partner and friend in concern, but figures that she'll tell her what's going on if she wants to talk.

[chasingangela]

Angela flashes a shy smile at Phoebe. "It's nothing."

[sensethevisions]

Phoebe looks concerned. "I won't pry, but I'm here if you need to talk."

[chasingangela]

Angela nods. "I really appreciate that."

*signs in, takes notes. Small tight smile of memory as he thinks about the earthquakes he's been in.*

[equalsmcsquared.livejournal.com]

Anything you'd like to add, Mr. Solo? *a slight grin*

[12parseckessel.livejournal.com]

Just that when the lava starts gushing up through the vents in the lithosphere, it's time to haul jets.

Sorry, Ma'am, I've had the pleasure of experiencing a few, er, tectonic incidents.

[equalsmcsquared.livejournal.com]

*nods* I appreciate your insights.

Thomasina gets to class on time, signs her name on the roll sheet and takes her seat at the table she shares with tru_relivesdays. Then she does as Ms. Sidle has directed and opens the handout before settling in to take notes in her exercise book, wondering more than a little at the idea of the ground deciding to move beneath one's feet even a little, much less to so great an extent as the lecture and the pictures in the handout would seem to indicate.

*Plate tectonics can be a frightening reality, as the recent tsunami demonstrated. And yes, Sara is also including news reports and footage of that incident in today's lecture.*

Connor slips into the room. His weekend was uneventful, save the difficulty sleeping because of the werewolves howling all night long.

He hasn't made any sort of effort to find a new lab partner since _notanumber bounced out of the class. He's sitting alone at his table, perfectly content to not have a lab partner.

[equalsmcsquared.livejournal.com]

*Well, she can hardly fuss at him since this is a lecture day.*

[leeadama.livejournal.com]

*sits in his usual desk at the front of the class and studiously takes notes and tries to hide his terrible and sulky mood*

[equalsmcsquared.livejournal.com]

*would coddle except, well, she doesn't coddle. ever.*

[alchemic-bean.livejournal.com]

*shows up to class and takes notes*

[defiantlyyours.livejournal.com]

*shuffles in*

*recalls horrifying time in detention*

*hands teacher methodically scrawled apology*

Very sorry. Terribly rude of me. If I have an issue I will deal with it in a civilized manner in the future. My sincere apologies.

Phoebe is taking notes and thinking of the few earthquakes she has been through in San Francisco.
