Geography 12: Oct. 5 & 6

 After some catching up from me being away here is where we are at:

IMPORTANT UPCOMING Dates:

Wed Oct. 7 - field work on Illecillewaet River.  

Tuesday Oct. 13:  test River Systems

Wed. Oct. 14:  Field work:  Rogers Pass (back at lunch)

Monday:  we started our connections model presentations, talked about rivers as agents of gradation.  We talked about erosion and transportation.

Erosion happens via Abrasion, Attrition, Hydraulic Action & Solution

Abrasion:  causes river bed to become deeper through the action of scraping or wearing away

Attrition:  stones and rocks knock together breaking into smaller particles so the bedload is breaking itself apart or by hitting the bed

Hydraulic Action:  the ability of moving water to dislodge and transport rock particles, breaking up the banks

Solution:  Water dissolved soluble materials

 

On Tuesday we went over and corrected our glaciation tests.  Did some review of the above and talked about River Deposition.  We also continued on with presentations of connections models.

Geog 12: Glaciation Review sheet

 Test/Large quiz is on Friday.  

Earth Matters Text book pages:  102-103, 132-139

There will be two diagrams to label.  There will be some short answer questions.  There may be a T/F section where you have to back up your answer.

Understand the terminology and how to apply it.

Understand how glaciation is an agent of gradation.

Be able to describe why a crevasse forms.

Be able to differentiate between erosional and depositional landforms.

Know the following terminology:

Glaciation:

Answers to Friday 5: September 18

These photos go with number 4.

 1.  Differentiate between the two types of glaciers.

-Alpine and Continental

Alpine glaciers begin high up in the mountains in bowl-shaped hollows called cirques. As the glacier grows, the ice slowly flows out of the cirque and into a valley. Several cirque glaciers can join together to form a single valley glacier.  Continental Glaciers cover all or parts of continents like Greenland and Antarctica.  They are continuous ice flows, small ones are called ice fields, large ones are known as ice sheets.

2.  Provide three ways glaciers contributions can be indicators of global warming (besides visual shrinking).

-increase in sea level through melting ice

-change in ocean ecosystems and ocean currents because of the increase in fresh water in the ocean

-decrease of salt in ocean can change the Gulf Stream changing the weather on land

-decrease of fresh water available for plants and animals on land

3.  List Erosional and Depositional features formed from glaciation.

4.  Explain with a diagram how crevasses are formed:

(see above pictures)

A crevasse is a deep crack that forms in a glacier. Crevasses form as a result of the movement and resulting stress associated with the movement of the ice.  

5.  Define Firn or Névé:

A Névé is a young, granular type of snow which has been partially melted, refrozen and compacted, yet precedes the form of ice.  It is associated with glacier formation.

A Firn is a type of snow that has been left over from past seasons and has been recrystallized into a substance denser than névé.

Geography 12, week of Sept. 14th

 Monday - we did some review including going over the Friday 5.  Students then headed to the library to get their text books:  Earth Matters.  From here we discussed last weeks video focussing on the two following questions:  What positive resources do we get from glaciers?  How are glaciers indicators of  global warming.  We answered these using specific examples from the video.  We then moved onto working on our glaciation sheet.  Finally we watched this video and worked on our glaciation sheets.

Wednesday:  Field Trip to Rogers Pass!  Assignment if you missed it ( pick up in library or from Ms. Mohn in the office).

Geog 12 - Answers to Friday 5, September 11

   1.  What are the two main types of Geography?  Differentiate between the two.

Physical & Human Geography

Physical geography deals with the natural features and processes of the Earth. It examines the physical characteristics of the environment and how these features and processes shape the planet.

Human geography looks at the relationship between people and their environments. It explores how human activities and cultures shape and are shaped by the physical landscape.

2.  List the 5 themes of Geography:

MR HELP

Movement, Regions (formal, functional, perceptual), Human-Enviro Interactions, Location (Absolute and Relative), Place (Human and Physical characteristics)

3.  Define one of these and provide an example:

(go through all 5)

4.  Lines of Longitude run in which direction.

N-S

5.  Name and describe one of the spheres.

*Atmosphere: This is the layer of gases surrounding Earth. It includes the air we breathe and plays a critical role in regulating temperature and weather patterns.

*Hydrosphere: This includes all of Earth’s water in its various forms—liquid, solid (ice), and gas (vapor). It covers oceans, rivers, lakes, glaciers, and groundwater.

*Lithosphere/Geosphere: This is the rigid outer layer of Earth, including the crust and the upper mantle. It consists of rocks and minerals and forms the ground and landmasses.

*Biosphere: This encompasses all living organisms on Earth, including plants, animals, fungi, and microorganisms. It interacts with the other spheres by affecting and being affected by their processes.

*Cryosphere: Often considered part of the hydrosphere, the cryosphere specifically refers to the frozen water parts of the Earth, like glaciers, ice caps, and sea ice.

Geography: week of Sept. 8th

 This week we talked a lot about what Geography is and how it is part of our day to day lives.  We talked about the different types of Geography including Human, Physical and Environmental Geography and the many sub-types that fall under these.  We learned about the 5 themes of Geography and watched a video to help us understand these.  We took notes on all of the above as well as discussed the 4/5 main spheres of the Earth.

We watched the following videos:

https://www.youtube.com/watch?v=vlVVaZhRAEA

https://www.youtube.com/watch?v=J1afrDnnyt4

https://www.youtube.com/watch?v=9KGiP

We started an assignment on the 5 Themes of Geography, it can be found here this is due on Monday Sept. 14th.

Friday 5 quiz on Friday.  You will also have time to work on your 5 themes assignment and we will start to look at glaciation in preparation for our field trip on Wednesday next week.  **please get forms in!!

On Friday we started the Glaciation unit.  We differentiated between continental and alpine glaciers and watched this introductory video.  We started some notes.  https://www.youtube.com/watch?v=WJgpDyP9ewQ

Five Themes of Geography Group work & Assignment:

 Group activity: 

1. Start with a conversation about what you’ve read, heard, and talked about in the lesson so far. Try to ensure that all members of the group understand the topic. 

2. Next, talk about how you will take on this task using the chart paper provided: 

Inventory of the Place Where You Live  • create a rough map that lists the natural (physical) characteristics of Revelstoke  • mention major landforms, vegetation, waterbodies (be descriptive and use names if you know them)  • add cultural (human-built) features and characteristics as well  • be thorough - try to work through all possibilities carefully

3. Now do it... part of this activity is learning more about how your group process works. 

Assignment (individual or group): take 5 pictures to show the 5 themes of geography. They can be from around the school or community. Be prepared to submit them to the class for viewing and possibly explanation (hopefully the pictures will speak for themselves). Try to make the pictures great, but don’t manipulate the context (change the setting to match the theme) -- look for existing examples. 

Geographers use 5 themes or principles of geography to gather, organize and analyze information.  This video goes through the themes again if you need a different explanation.

https://www.youtube.com/watch?v=J1afrDnnyt4

Assignment:
Using your notes/memory identify, describe and organize each of these 5 principles/themes into a graphic organizer (visual web/mind map).  The place may be a city or town, a park or holiday destination:  basically somewhere large enough to describe in geographic terms).  Each theme should be defined and then provide examples from your location/chosen place to help explain your definition (place that you know well and are able to describe (favourite holiday spot, summer cabin, grandparents city etc...).  Your examples should include one photograph.

Your mind map should have three levels of information:
1.  5 organizing principles
2.  Definition of each of 5 principles/themes
3.  Example of definition from the place you have chosen.  Your example should include a description for clarity

*The purpose of this web/mind map is to show you understand the 5 organizing principles/themes
You could also achieve this with photographs/pictures connecting to the definition.

ASSIGNMENT IS DUE:  MONDAY SEPT. 14TH (by the end of the day)
