NAME: _______________________________
LEARNING OUTCOME 2: Investigate and interpret linkages among landforms, water
and climate
2a. Describe the processes of erosion and deposition resulting from wave
actions and water flow
2b. Investigate and describe stream characteristics
2c. Describe processes leading to the development of ocean basins and
continental drift.
2d. Identify evidence of glacier action and analyze factors affecting the growth and
attrition of glaciers and polar icecaps
EROSION vs. DEPOSITION

CHEMICAL WEATHERING also causes erosion
as seen here in the Kartchner Caverns.

and deposition. Thinking about the Sheep River and by reading page 355 to 358,

2.3 PROCESSES THAT SHAPE OCEAN BASINS AND CONTINENTAL DRAINAGE
(page 361-365)
Water has changed the landscape by waves, tides and rivers, but Continental Drift
has shaped the ocean basins and the continents (mountains) thus creating
Continental Drainage Systems.
1. In grade seven you learned that the outer part of the Earth is called the
_____________________________, which is broken into huge plates that are
constantly moving (apart or towards each other) ever so slowly.
2. When two plates are moving away from each other ________________ and
_________________________ shelves are formed.
3. When two plates are moving towards each other ___________________ and
mountains are formed.
4. The changing LITHOSPHERE affects the major drainage patterns of our
continents. The CONTINENTAL DIVIDE (the highest land on the continent), or
the Rocky Mountains in North America affects where water flows:
a. West of the Continental Divide water goes to _________________________
b. East of the Continental Divide water goes to either
_______________________ or ____________________.
c. Some water will drain to the Hudson Bay, or even to the Gulf of Mexico!

Major Drainage Basins for
Canada:
5. Mountains may have been formed by plate tectonics, but large bodies of ice
known as _________________________ (continental glaciers or icecaps) have helped
carve much of North America’s surface.
6. If a region is cold the snow and ice melt very little and as it builds up these
__________________ glacier starts to flow down high valleys and between mountain
peaks.
7. As the glacier moves, ____________ of ___________ (tiny fragments to huge
boulders) become embedded in the ice. As they move the ground beneath the
glacier is ground down (reshaped).
8. When the climate is warmer the glacier melts back or retreats (page 363 Frozen
History!) As the glacier retreats it leaves behind __________________, ___________
and ________________ it once contained—THUS CHANGING THE LANDSCAPE!
Hence OKOTOKS BIG ROCK!!

c. _____________________
