Room 611: Wednesday, October 13. 2021

Today's schedule is BADC

B Block Physical Geography - Today we'll finish the Discovery Channel Raging Planet Volcanoes episode...Sweet!

We'll also look at the differences between explosive and effusive volcanic eruptions (think silica and gas).

When it comes to liquids, viscosity is a measurement of how thick or flowy it is. When lava has low viscosity, it can flow very easily over long distances. This creates the classic rivers of lava, with channels, puddles and fountains. You can also get bubbles of lava filled with volcanic gasses that burble and pop on the surface of the lava. When lava has a high viscosity, it’s very thick and doesn’t flow very well at all. Instead of rivers of lava, you can get crumbling piles of rock flowing down hill. It can also clog up the volcanic vent and form blocks that resist the flow of lava. Viscous lava will trap pockets of gas within the rock, and not let them pop as bubbles on the surface.

The types of magma produced in the various volcanic settings can differ significantly. At divergent boundaries and oceanic mantle plumes, where there is little interaction with crustal materials the magma tends to be consistently mafic (which is a low viscosity magma). At subduction zones, where the magma ascends through significant thicknesses of crust, interaction between the magma and the crustal rock—some of which is quite felsic (which is a high viscosity magma)

and yes...I Lava You Volcanoes!

Check out the types of Volcanoes at the BC Open Text Physical Geology Textbook. There are

three types of volcanic environments are represented in British Columbia:

The Cascade Arc (a.k.a. the Garibaldi Volcanic Belt in Canada) connected to subduction of the Juan de Fuca Plate beneath the North America plate (Mt. Garibaldi, Mt. Cayley, and Mt. Meager)
The Anahim Volcanic Belt related to a mantle plume (The Rainbow Range and Nazko Cone)
The Stikine Volcanic Belt and the Wells Gray-Clearwater Volcanic Field related to crustal rifting (Tseax River Cone and Mount Edziza)

A Block Criminology - Today we'll continue our focus on violent crime looking at rape and sexual assault in Canada. We'll examine what a sexual assault is along with the three levels of sexual assault in Canadian Law. After I'd like you to focus on a question about Groth's typology of rapist. Nicholas Groth created a typology based upon the degree of aggression, the underlying motivation of the offender and the existence of other antisocial behaviors, which resulted in four types of rapists.

So, my question is, using the Crim text and this Sex Offender Typology website...

Explain the three types of rapist according to Groth (anger-retaliation; power reassurance and assertive; and sadistic)

After, I need you to answer the question:

Identify and explain the causes for sexual assault

You'll need to look at evolutionary and biological factors (remember Sigmund Freud's Thantos and Eros or instinctual drives that allowed species to be successful)? Look at modern male socialization (boys are taught to be aggressive, forceful, tough, and dominating...think about how boys play when they're young) and then at hypermasculinity (where some men have callous sexual attitudes and believe that violence is "manly"). Lastly consider both violent experiences (remember that those boys who were exposed to violence in the household are more likely to commit violent acts when they grow older) and sexual motivation (social, cultural, and psychological forces...think about the messages hidden in Axe body spray commercials). What message does this commercial send to people...

Now consider what the commercial indicates about sex in modern society. Who is the commercial targeted at and what are the sexual roles in the commercial.

And if you're still struggling with consent...

D/C Blocks Social and Environmental Sciences - Back in the learning commons/library today to begin/continue work on your water conflict poster project. Remember:

Why is there a crisis over water in your area? What social and environmental factors do you think are contributing to the water crisis? What are common factors that go along with the water disputes, such as political instability, social unrest, economic downturn, heavy unemployment, civil warfare, etc.?
Who are the “players” or "stakeholders" in this conflict? What are their motives and interests in the water dispute?
What is the water source in question (river, aqueduct, canal, watershed, tributary, reservoir, dam, etc.)? How large is the water source, and how large is the area through which the water source flows? Approximately how many people use this waterway as their main source of water?
Where in the world and in the country and/or region is the water source? Identify the waterway on a map, and highlight areas of the map involved in or affected by the issues in dispute (locations of villages, industries, crops, next closest water source, other water sources, country/clan borders, etc.).
How would the water source be affected by different outcomes of the water dispute? Use different colors or a symbol to indicate how the water source would be diverted, dammed or re-aligned. How would the items you highlighted in the previous question be affected by these changes?
How, if at all, would this water conflict be resolved? What is the current state of the dispute, if it is ongoing? What are solutions to the water crisis? Can you come up with ways that would provide the basis for a water-sharing plan?
