Watersheds & Human Impact Vocab & Ques

Water from precipitation that drains into a gully  that slows into a stream, which in turn flows into a river lake, reservoir, estuary, wetland, or the ocean.

• surface water
• ground water
• runoff 
• drainage

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.

A student drew the model below to represent a part of a watershed and some human activities that affect the watershed.

How do the industrial, agricultural, and residential activities of humans most likely affect the groundwater in the area

• The activities prevent most of the water from evaporating into the atmosphere.

• Pollutants from the activities percolate through the soil and enter the water table.

• The activities replace the groundwater used.

• All of the above

Why is gravity a factor in watersheds? 

• it causes the water to flow away from a watershed
• it causes the water to flow down towards a watershed

• Fertilizer can cause groundwater to freeze

• Fertilizer can cause groundwater to become undrinkable

• It will seep into the school
