ES 7-2: Streams, Lakes, and Wetlands

What is the primary factor that influences the development of a stream?

• The amount of vegetation in the area

• The gradient or slope of the land

• The presence of wildlife

• The type of soil

Explain how a V-shaped valley is formed by a stream.

• Through the deposition of sediments

• By the lateral erosion of the stream

• By the vertical erosion of the stream cutting into the bedrock

• Through the action of glaciers

Streams lengthen through ____.

• eutrophication

• suspension

• headwater erosion

• upstream flooding

Describe the process of meander formation in a stream.

• Meanders form when a stream flows over a steep gradient

• Meanders form due to the deposition of sediments on the outer banks

• Meanders form as a result of erosion on the outer banks and deposition on the inner banks

• Meanders form when a stream flows in a straight line

What is an oxbow lake and how does it form?

• A lake formed by a dam, created when a meander is cut off from the main stream

• A lake formed by glacial activity

• A lake formed by volcanic activity

• A lake formed by tectonic movements

Identify the conditions under which an alluvial fan is likely to form.

• In a flat desert area

• At the base of a mountain where a stream exits a narrow valley

• In a coastal region

• a sudden decrease in stream gradient

• streams capture another stream

• streams overflowing banks

Analyze the impact of stream rejuvenation on the landscape.

• It leads to the formation of new meanders

• It causes the stream to deposit more sediments

• It results in the deepening of the stream valley and the formation of terraces

• It causes the stream to dry up

What are the primary origins of lakes?

• Glacial, tectonic, volcanic, and fluvial processes

• Only glacial processes

• Only tectonic processes

• Only volcanic processes

Explain the process of eutrophication in lakes.

• The process of lake formation through tectonic activity

• The process of nutrient enrichment leading to excessive plant growth and oxygen depletion

• The process of sediment deposition in a lake

• The process of water evaporation from a lake
