• a water system with high turbidity

• a water system with low turbidity

• a water system with no turbidity

Which best explains how nutrients, salt, sediment and pollutants get into estuaries and oceans?

• from precipitation falling over the estuaries and oceans

• from organisms living and dying in estuaries and oceans

• from rivers and streams flowing into estuaries and oceans

• from asteroids and comets impacting Earth at estuaries and oceans

Which accurately describes the relationship between nutrients and life-forms in an estuary?

• As nutrients increase, the number of life-forms increases.

• As nutrients decrease, the number of life-forms increases.

• As nutrients increase, the number of life-forms stays the same.

• As nutrients decrease, the number of life-forms stays the same.

A small city gets its drinking water from the river running through its center. This river is fed by rivers that flow down the mountains nearby. How would excessive rainfall in the mountains most likely affect the turbidity of this local water source?

• Heavy rainfall would decrease the turbidity of the river downstream.

• Heavy rainfall would increase the turbidity of the river downstream.

• Heavy rainfall would increase the turbidity of only rivers upstream.

• Heavy rainfall would decrease the turbidity of only rivers upstream.

Turbidity measurements were taken at different distances from the shore of a lake.

• Shoreline erosion causes sediment to wash into the lake.

• Sediment is carried from the middle of the lake to the shore by wind.

• Swimmers stir up sediment by splashing in the water near the shore.

• Fish stir up sediment while feeding on plants that grow close to the shore.
