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
What is a watershed?
Water in an area
Water that flows into a river or stream
Land that water flows over and through
Water that is salty
Wastes produced by agriculture, households, industry, mining, and other human activities can end up in ______________.
groundwater
streams and rivers
oceans
All of these choices
What definition BEST describes a watershed?
An area where water infiltrates the soil
An area where aquatic plants and animals thrive
An area where snow melts and changes into liquid water
An area that collects precipitation and drains it to the lowest point
An area of land where all the water flows to one location, like a funnel.
Superfund Site
Watershed
Succession
River
What is the primary effect of urbanization on watersheds?
Increased water absorption by soil
Decreased wildlife diversity
Increased surface runoff
Enhanced natural water filtration
Why is it important to maintain healthy watersheds?
They can generate electricity
They support biodiversity
They are a primary source of mineral resources
They increase land value for real estate
A watershed is affected by human activity in a number of ways. When it rains the pollution (a)
runoffs into lakes/rivers
increases the fertilizers for crops
Which of the following activities can negatively impact a watershed?
Planting native vegetation
Building dams
Implementing soil conservation measures
Reducing pesticide use
Fertilizer can seep through the ground to reach groundwater, what effect can it have?
Fertilizer can cause groundwater to reverse flow
Fertilizer can cause groundwater to freeze
Fertilizer can cause groundwater to become undrinkable
It will seep into the school
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 of these chemical on the environment?
Runoff carries these chemicals into lakes and streams.
Theses chemicals cannot be purchased in large bulk.
These chemicals are expensive to produce.
Storage space for these chemicals is limited.
If a homeowner dumps paint into the yard, the paint will ________________________.
stay on the surface and cause no problems
sink into the ground a cause no problems
contaminate groundwater and surface water
contaminate the air when it evaporates
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
Runoff from agricultural land carries chemicals from fertilizers that collect in a lake. The buildup of chemicals can eventually cause--
aquatic life, such as fish and turtles, to die from lack of oxygen
excess water to fill the aquifer
river tributaries to reroute, changing the flow of waterways
rainfall levels to drop
Overflow during a heavy rainstorm from a wastewater treatment plant would result in –
polluted runoff into nearby ponds.
flooding in the local aquifer.
weakened housing foundations.
over-treated drinking water.
The movement of colored water through the gravel best models —
condensation of water vapor
surface runoff of precipitation
conservation of water
pollution of groundwater
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.
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
