Q

How does the moon affect the tides?

A

The moon never truly orbits the earth, earth and moon together orbits the center. Tidal bulges occurs due to centrifugal force and the moons gravity.

22
Q

What species clam up as an adaptation?

A

Clams, mussels, barnacles, limpets, bivalves, and snails

23
Q

What species dry up as an adaptation?

A

Mollusks and brown algae

24
Q

Describe the black zone

A

Upper most zone. It is covered by spring tides every two weeks. Blue green algae and lichens give rocks there black color.

25
Q

Barnacles zone

A

Covered and uncovered twice daily. Tides deliver food

26
Q

Rockweed zone

A

Brown algae called irish moss dominates this zone. It can form a spongy carpet.

27
Q

Blue mussel zone

A

Blue mussels are very common. Zone is mostly submerged in water

28
Q

Kelp zone

A

Lowest zone, may be uncovered every two weeks. Kelp a brown algae dominates this zone.

29
Q

Wetland

A

A transitional habitat. Major source of policy.

30
Q

Three wetland characteristics

A

Shallow water or saturated soils at some time during the year. Accumulate slowly decomposing organic matter. Plants and animals adapted to the saturated conditions.

31
Q

What are some ecosystem services of a wetland?

A
32
Q

Marginal wetland

A

Soils are inorganic and are overlaid by organic. Rivers, lakes, and the sea provide source water.

33
Q

Fringed wetland

A

A type of marginal wetland that has a constant water supply.

34
Q

Flood wetland

A

A type of marginal wetland

35
Q

Mires

A

Independent of water bodies. Gets source water from rain or runoff

36
Q

Minerotrophic fen

A

A type of mire fed by ground water and surface runoff.

37
Q

Ombotrophic bog

A

Above the water table and fed by rainfall

38
Q

Marsh

A

USA: dominated by trees. Europe: above the water table

39
Q

Swamp

A

USA: dominated by non woody vegetation. Europe: at or just below the water table.

40
Q

Three things needed for wetland delineation

A

Hydrology: where is the water table, soil: is there gleying. Plant life: are there plants that can only survive in a wetland?
