Thursday, May 25th: WED- Weathering, Erosion, and Deposition

LEARNING TARGET: I will understand and be able to identify different types of weathering.

VOCABULARY (We will do vocabulary boxes for each word.)

  1. sediment-solid material that is moved and deposited in a new location.
  2. sediment examples– Rocks, minerals, the remains of plants and animals. May be as small as a grain of sand or as large as a boulder.
  3. landform-A natural feature on the Earth’s surface.
  4. landform examples-Four major types: mountains, hills, plateaus, and plains. Minor include: buttes, canyons, valleys, basins, deltas and many, many others.
  5. weathering– The breaking down of rocks and other materials on the Earth’s surface.

OVERVIEW: Weathering, Erosion, and Deposition

 

JOURNAL ENTRY: INPUT WEATHERING

  1. IMG_0268Title and date your page.
  2. Write the definition of weathering under the title.
  3. Glue the foldable in your journal so that it may open (see picture below).
  4. Use the resources below the journal entry description to fill in the information on the types of weathering.
  5. Open each flap. On the lined journal page, write the name of the type of weathering, the definition and/or description.
  6. On the opposite side (see image below) find three different types of this kind of weathering and describe how each happens.
  7. Finally- draw and color one example of each type on the outside of the “flap” as shown above.

DEFINITIONS

  • PHYSICAL WEATHERING-The breaking down of rocks and earth without changing the chemical make-up. They are broken apart by a physical force.
  • BIOLOGICAL WEATHERING-The breaking down of rocks and earth by living organisms such as plants, animals, and bacteria. Can be physical or chemical.
  • CHEMICAL WEATHERING– The breaking down of rocks and earth due to chemical reactions that happen between the minerals in rocks and the environment.

THE MAIN TYPES OF WEATHERING: Chemical, Physical, and Biological (Journal page entry)

  1. BBC Weathering– http://www.bbc.co.uk/bitesize/ks3/science/environment_earth_universe/rock_cycle/revision/6/
  2. The Geological Society: Weathering- https://www.geolsoc.org.uk/ks3/gsl/education/resources/rockcycle/page3461.html

NOTE: Sometimes weathering is described as MECHANICAL and CHEMICAL

Weathering can be sorted into three groups: PHYSICAL, CHEMICAL, and BIOLOGICAL. People also sort weathering into two groups: MECHANICAL and CHEMICAL.

What’s the difference?

  • MECHANICAL weathering is basically includes all PHYSICAL weathering with BIOLOGICAL actions that break down the earth such as roots growing into rocks and animals burrowing through the ground.
  • CHEMICAL weathering includes all of the chemical break down of rocks including acids produced by plants that weaken and break down the rocks and the earth.
