Geog 12: Oct. 21

 Geography 12 today went over tests on River Systems and corrected these.  From here we moved onto Coastal Landforms (our last section in the Gradation unit).  We watched these two vids:

And then we did this worksheet/work:

Matching Worksheet: Coastal Features

1. A landform created by the accumulation of sand along shorelines.

2. An area where freshwater meets saltwater, often rich in biodiversity.

3. A submerged, glacially-carved valley filled with seawater.

4. An area where sediment is deposited at river mouths.

5.  A coastal body of water connected to a larger body of water, such as a sea or lake. These are usually semicircular or nearly circular in shape

6. A marine structure built by coral polyps, supporting diverse marine life.

7. The periodic rise and fall of sea levels caused by the gravitational pull of the moon.

8. Opening in a mass of steep rock, often found in coastal areas

9. Zig-zag movement of weathered materials along a beach caused by the swash and backwash of waves

10. Steep rock formations formed by coastal erosion.

11. Rock vertical island, often a pillar that is a remnant of a sea cliff

12. A cape in a lake, sea, or ocean that ends with a steep cliff.

13.  a deposition bar or beach landform off coasts or lake shores

A. Coral Reef       B. Cliff              G. Estuary            J. Longshore drift M.  Arch

C. Delta.               D. Tides            H. Headland         K. Sand spit

E. Fjord.               F. Beach            I. Stack                 L.  Bay

Label the diagram below with as many features as you can:

Place all the features into either the Erosional category or Depositional category.

Geog. 12: Answers to Friday 5, Oct. 18

 1.  Mass wasting causes material to move downhill, the energy that is exerted is determined by.....give two examples.

  • Steepness of slope
  • Shape and size of particles
  • Nature of material that forms slope
  • Depth of the material
  • Nature of ground cover
  • Stability of the ground
  • Water content of the soil
2.  Karst topography refers to....
-Karst topography is landscapes that form underground where the rock is porous; this occurs due to the dissolution of soluble rocks primarily limestone but also dolomite and gypsum

3.  Provide two examples of erosional and two examples of depositional aeolian landscapes.

Erosional

Depositional

-wadis

-barchan dunes

-pedestals

-star dunes

-balancing rocks

-transverse dunes

-arches

-parabolic dunes

-erg

-longitudinal dunes

4. What are the two characteristics that allow Aeolian landscapes to form?

1.  reduced moisture content b/c dry soil doesn’t stick together so more susceptible to wind 
2.  Lack of ground cover/surface vegetation means soil not protected by root systems so wind erosion is greater

5.  List as many Geographic Thinking concepts as you can and explain one.

  • Geographic significance
  • Use Primary Evidence 
  • Identify Patterns and Change, 
  • Analyze Cause and Consequence
  • Understand Interactions and Associations 
  • Take Geographic Perspectives/sense of place
  • Consider Ethical dimensions/Geographic value judgements
Bonus:  List 3 Karst features
  • stalagmites
  • stalactites
  • rock curtain
  • pillar
  • sink hole/doline
  • caves
  • disappearing streams
  • grykes
