1.  Write the answers on your bellwork.  1. The inside of the earth is made up of ____ layers, the _______, ________, ________, and ____.  2. The _____ has magma, which flows in a _________ pattern.  3. The crust and mantle are made up of _____, while the inner and outer core are made up of ______.  4. The theory that there was one super continent is called ________ _______.  5. The crust is made up of many ______. When they move, we call it ________ _______.  6. Plates move at boundaries. We call these boundaries _________, __________, & __________.

2.  1. Bellwork (review of layers of the Earth)  2. Notes, Landform Creation  3. Videos, Erosion  4. HW: ◦ Honors – explain the difference between erosion and weatherine ◦ Standard – create a “cartoon strip” with one block for each of the four spheres of the outer Earth.  Remember: Map Quiz on Wednesday, Quiz 2.1 next week

3.  Objective: To discern the difference between primary and secondary landforms  Question: How are landforms created?

4.  4 outer spheres to the Earth ◦ Lithosphere = Earth’s crust, landforms ◦ Hydrosphere = Earth’s water ◦ Biosphere = Earth’s living things (plants, animals, fungi, humans, etc) ◦ Atmosphere = Earth’s gasses, winds, weather

5.  Landform = a geographical feature of the Earth, created by a natural process

6.  How are landforms created? ◦ 1. Internal Process (Plate Tectonics):  Example = mountains, volcanoes, islands, fault lines, rift valleys ◦ 2. External Process  Erosion  Weathering  Sediment Deposit

7.  Erosion = the wearing away of a solid over time by natural causes ◦ Usually happens by wind, water, ice

8.  Weathering = decomposition of Earth’s materials because of direct contact with the atmosphere/chemicals

9.  How are Erosion and Weathering Different? ◦ Both wear away at landforms to mold them ◦ Erosion uses wind, water, or ice to move particles to a new location, where it deposits them ◦ Weathering is a process where the particles are gone forever, due to a chemical reaction or decomposition

10.  Sediment Deposit = when Earth’s particles are carried by wind, water, or ice from erosion elsewhere and left in a new place (deposited)

11.  Erosion Video Erosion Video  Glacier Video Glacier Video  Weathering Video Weathering Video

12. 4 outer spheres of the Earth Examples – match to sphere  1. atmosphere  2. biosphere  3. hydrosphere  4. lithosphere  A. rock  B. tree  C. fungus  D. lake  E. groundwater  F. oxygen  G. sandy beach  H. cloud  I. wind  J. grass

13.  1. Bellwork – Review outer spheres of the Earth (Check HW)  2. Landform Creation, Finish Notes  3. Standard: Videos Honors: Google Earth Tour  4. HW: Standard – Primary/Secondary matching  MAP QUIZ TOMORROW, Quiz 2.1 Next Tuesday

14.  Primary Landforms = those created through tectonic activity  Secondary Landforms = those created through erosion, weathering, or sediment deposit.

15.  Alluvial Fan : deposit formed at the bottom of a mountain, valley, or canyon from a fast flowing stream or river

16.  Valley = deep area between two mountains, carved out by glaciers or rivers

17.  Canyon: deep ravine between two cliffs carved out by a river

18.  Delta: landform at the mouth of the river, where it flows into the ocean, where there is a deposit of soil, sand, and rock (good for farming)

19.  Plateau/Mesa = flat topped mountain or hill, with sides carved by wind over time

20.  Continental Shelf – a part of the continental crust of a continental plate, is the edge of each continent

21.  Put these landforms into the chart off the board based on the type of landform they are:  Continental shelf  Fault  Glacier  Plateau  Volcano  Delta  Mountain  Rift Valley  River Valley  *If you don’t know what a landform is, Look it up!
