Forms of Water in Atlantic Canada Homework questions

1. River: a long narrow body of water that flows in a channel from high to low land and empties into a body of water such as an ocean or lake. Lake – a body of water completely surrounded by land. Pond-a fairly small body of still water.

2 – Areas with igneous bedrock, rock formed from magma after volcanic activity, overlain with thin soils tend to have numerous lakes and ponds. NFLD is an example of this. 3.

3. Area with sedimentary bedrock, rock formed by build up of layers of rock particles, overlain with thick soils tend to have more rivers and streams. PEI is an example.

4. Wetlands are neither solid ground or open water, but water logged areas: bogs, fens, swamps and marshes.

5. Bogs are composed of mainly peat, a thick mass of decomposing plants formed over thousands of years.

6. Plants that grow in bogs are: mosses low shrubs black spruce

7. The difference between a bog and a fen is that bogs are fed by rain or snow and fens are fed by streams.

8. 2 examples of marsh plants: Cattails Water lilies

9. Two main bodies of water that influence Atlantic Canada are: Atlantic Ocean Gulf of St. Lawrence

10. Gulf – a very large area of the sea that is partially enclosed by the land. Bay – a partially enclosed body of water that has an opening to the sea, smaller than a gulf, closer to the shore.

11. Ocean waves pound the coastline and wear away rock, soil and even boulders. Overtime, solid rock is reduced in size, smoothed or rounded and shorelines move further into the land.

Wetlands are compared to kidneys because the plant filled channels filter slow moving water, trapping sediments and contaminants. The water that drains from a wetland is clear and clean.
