Thursday, September 15, 2016 EXPECTATIONS
Entry Task: Go to the 3rd page AFTER all of the blank lined T chart pages. Read the 3rd page called “Landforms” by Sharon Fabian and answer the questions on the page after that. EXPECTATIONS 1. Have your pencil, LA book, BIN, and binder. 2. Be in your seat before the bell. 3. Honor the speaker. 4. Listen to the countdown.

Landforms in Geography
Geography is the study of both people and the lands that they live in. An important part of studying the land is learning about landforms and understanding how the land was created and how it affects people
3
Got Vocab? Landforms: (n.) The shapes of land on Earth’s surface. Two examples of landforms are rivers and mountains.
4
Plate Tectonics 1 The Earth’s crust is divided into 7 major plates that float and move on top of liquid rock.
5
1 Plate Tectonics Pangaea is an example of plate tectonics. According to this theory the Earth had only one land mass that slowly began to pull apart.
6
Divergent Plate Boundary
2 Occurs when two plates are moving apart from each other Can occur on land or under water.
7
Mid Oceanic Ridge 2 The Mid Oceanic Ridge is an example of a divergent plate boundary. It is an area where plates pull apart and magma rises to create new crust. Created by a divergent boundary
8
Convergent Plate Boundary
3 Happens when two heavy continental plates collide and create mountains
9
Himalayan Mountain Range
3 Created when the Indian Plate crashed into the Eurasian Plate The Himalayas are an example of a convergent plate boundary Mt. Everest in the Himalayas continues to grow 1 cm per year
11
Subduction Plate Boundary
4 Subduction Plate Boundary Happens when a heavier ocean plate moves underneath a lighter continental plate The diving plate melts in the Earth’s mantle and becomes magma. Magma then rises through the Earth’s crust and erupts as lava

Friday, September 16, 2016 EXPECTATIONS
Entry Task: Go to the 1st page AFTER all of the blank lined T chart pages. Read the 1st page called “What is Geography ?” by Cindy Grigg and answer the questions on the page after that. EXPECTATIONS 1. Have your pencil, LA book, BIN, and binder. 2. Be in your seat before the bell. 3. Honor the speaker. 4. Listen to the countdown.
13
Cascade Mountain Range
4 When an oceanic plate slid under a continental plate, magma rose and created volcanic eruptions which created mountain ranges like the Cascades. The Cascades are a good example of subduction plate boundaries.
14
Transform Boundary 5 Occur when plates slide past one another in the opposite direction. Plate edges often become stuck and pressure builds. Can you guess what happens when the plates become free?
15
San Andreas Fault 5 The San Andreas Fault is an example of a transform boundary. It is responsible for many earthquakes in California.
16
1906 San Francisco Quake 5 Happened when the San Andreas Fault moved 22 ft. The earthquake and resulting three day fire are responsible for destroying the city and killing an estimated 700 people.
20
Weathering 6 The process of breaking down landforms to create new ones. Large pieces of rock are broken down into smaller pieces
21
Ways to Break a Rock 6 HEAT can cause rocks to become so hot that they crack WIND can slowly carve away at rocks These are both examples of weathering.
22
Ways to Break a Rock 6 Water seeps into rock cracks, expands when frozen, and pries rocks apart. As water moves it cuts into rock and creates valleys These are two more examples of weathering. Picture of chemicals in lichen eating rock
23
Ways to Break a Rock 6 CHEMICALS slowly eat away at rocks until they break Another example of weathering Lichen eating a rock
24
Ways to Break a Rock 6 All of this is possible because of TIME
25
The Power of Weathering
6
26
Erosion 7 Once the rock is broken, it is moved away by water, ice, or wind and settles to create new landforms. Water most commonly creates erosion
27
Erosion 7 Water and ice is usually responsible for carrying rocking material/ sediment away and depositing it somewhere else Glacial weathering
28
Landforms Created by Water and Ice Erosion
7 Examples of Erosion Plain Alluvial Fan Delta

Let’s Practice Go to page 7 AFTER the blank T chart pages.
Read page 7, answer the questions on page 8. Read page 9 and answer the questions on page 10.
36
Round Robin Vocabulary
Each student will have two minutes to write the definition and draw a picture for each term on their vocabulary sheet. Word Mountain Definition and Example A land mass that projects above surrounding landforms and is above 2,000 ft. Illustration
37
Write the definitions with these terms.
BINGO! Write the definitions with these terms. Archipelago Delta Isthmus Plain Atoll Desert Lake River Basin Dune Mountain Strait Bay Fjord Oasis Valley Canyon Glacier Ocean Volcano Coast Gulf Peninsula Coral Reef Island
38
Passing Vocab. Panels
39
I Have You Have Landforms!
Each student will receive their own vocab card The game begins with the teacher reading a term’s definition. Students look at their cards to see if they have the term that matches the definition. The student who has the term then reads the new definition on their card aloud. I Have… Desert Who has… An area in the desert with a water source.
