Lesson 4
Pond- a fairly small body of still water.
Wetlands- neither solid ground nor open water.
Bogs- composed mainly of peat, a thick mass of decomposing plants, formed over thousands of years.
Fens- are similar to bogs but fed mainly by streams, the water table is usually at or above the surface.
Swamps- contain mature trees such as black spruce, or tall shrubs like alders and willow.
Marshes- areas permanently or seasonally covered by water; sedges, grasses and rushes (cattails and water lilies). They are divided into channels that carry off the water.
Gulf- a very large area of the sea, partially enclosed by the sea.
Ocean- a very large body of salt water: Atlantic, Pacific, Indian, Arctic.
Bay- a partially enclosed body of water with an opening to the sea.
Why are wetlands so fragile?
- Why are there no high mountain peaks in the Atlantic Provinces?
- Millions of years of erosion have dwindled them down to their present size.
- Define a fiord? A long narrow inlet of the sea, bordered by steep mountain slopes.
- Why are the Appalachian Mountains generally rounded in appearance? 300 million years of weather and erosion.
- Define the following:
