Unit 11 - Watershed

Pollutants from a highway enter a stream or creek and travel to a river. River water tested with the pollutant found is called  

• point source pollution
  Available space for crops
• nonpoint source pollution.
• eutrophic pollution
• riparian pollution

What is a stream or river that feeds into a larger body of water?

• Tributary
• Estuary
• Bay
• Watershed

What is Point Source Pollution?

• When you cannot trace the direct source of pollution

• When you can trace the point of the source - "pipe to source"

When fertilizers enter surface water, they cause problems in 
the watershed by -

• increasing the amount of nutrients available to fish in lakes and streams.
• 
  clogging narrow streams and preventing water from flowing properly.
• raising the water level in nearby rivers to levels leading to flooding.
• causing rapid algal growth that decrease oxygen levels and choke aquatic life.

The use of pesticides and fertilizers is carefully monitored 
because of the effect they can have on the environment. 
Which of the following is a possible negative effect of the use

What is a watershed?

• Land that collects and channels water from a small body of water to a larger body of water and the ground water below.

• the shape of the land determined by elevation

• A natural stream of water of considerable volume

• a river and all its tributaries

What is a divide?

• a natural stream of water of considerable volume
• a continuous ridge that separates a watershed
• small rivers or streams that flow into a larger river or stream
• a body of fresh water found in low lying areas

Define tributaries

• small rivers or streams that flow into a large river or stream
• a natural stream of water of considerable volume
• precipitation that flows over the land to streams
• a continuous ridge that separates a watershed
