Surface Water Review

What is the process by which a body of water becomes enriched in dissolved nutrients (such as phosphorus & nitrogen) that stimulate the growth of aquatic plant life usually resulting in the depletion of dissolved oxygen.

• limestone

• alluvial fans

• oxbow

• eutrophication

How can human activity cause eutrophification?

• by the over use of agricultural fertilizers that contain nitrogen & phosphorus

• by the over use of herbicides and pesticides

• by the over-fishing of ponds and lakes

• by the damming of streams

Select all circumstances that decrease runoff.

• soil with high percentage of coarse particles such as sand

• soil with a high percentage of fine particles such as clay

• light, gentle precipitation

• soils that contain grasses and other vegetation

• steeply sloped land

Estuaries are characterized by

• waterlogged soil that is rich in Sphagnum and are not stream-fed but received their water from precipitation

• grasses, reeds, sedges, and rushes, along with an abundant wildlife

• low-lying areas near streams that can develop from marshes that have filled in sufficiently to support the growth of shrubs and trees,

• large rivers that empty into an ocean and form brackish water

An artificial barrier that has the ability to impound water, wastewater, or any liquid-borne material, for the purpose of storage or control of water is known as a

• levee

• dam

• channel

• plain

Which of the following is a reason why wetlands are important?

• It acts as a filtering system
• It's a place where birds die
• It lets water pass through

Which type of wetland has peat moss and receives most of its' water from precipitation?

• Bog
• Marsh
• Swamp

How do wetlands help prevent flooding?

• They provide habitat
• They absorb extra runoff
• The provide nutrients

Imagine you see a shallow-water area with large trees whose trunks grow from underwater. What type of wetland are you most likely seeing?

• bog

• swamp

• marsh

• rainforest

These are the three main jobs of wetlands.

• provide habitats, store flood waters, purify water
• provide habitats, store plant life, purify water
• purify water, store wildlife, provide habitats
• purify the land, store flood waters, provide habitats
