Why does cold salty water sink?
It is less dense
It is more dense
It has a higher specific heat
It has a lower specific heat
Where does cold water from the poles go?
To Canada
To the equator
To the opposite pole
To Australia
What happens to deep ocean water as it reaches the equator and warms
It evaporates
It sinks (because warm things sink)
It rises (because warm things rise)
It condenses into clouds
Which of the following describes upwellilng
A wind driven process in which cold nutrient rich water moves to the surface
A wind driven process in which warm nutrient rich water moves to the surface
A process driven by convection in which warm nutrient depleted water moves to the surface
A process driven by convection in which cold nutrient depleted water moves to the surface
Which process connects surface water to groundwater?
evaporation
transpiration
photosynthesis
infiltration
A tributary is
where all the water in a river system drains
an area of low-lying ground adjacent to a river which is subject to flooding
a small stream that feeds into a larger one
A watershed is
where all the water in a river system drains
an area of low-lying ground adjacent to a river which is subject to flooding
a small stream that feeds into a larger one
A floodplain is
where all the water in a river system drains
an area of low-lying ground adjacent to a river which is subject to flooding
a small stream that feeds into a larger one
Which of the following would cause a flood?
Excessive rain
ruptured dam or levee
rapid melting of snow or ice
All of these could cause a flood
When nutrients and waste runoff into the water it can create algal blooms. These blooms block the sunlight and eventually deplete the oxygen in the water leading to mass die offs in the waterway. What is this?
Runoff
Eutrophication
Bioaccumulation
Invasive species
Which of the following are important functions of wetlands
water quality/purification
flood protection
habitat
All of these are important functions of wetlands
What human activities that can damage wetlands?
draining the water, pollution, introduction of invasive species
agriculture, burning, native species
restrictions on pollutants, conservation, sustainable practices
Which of the following describes an estuary
an area where a freshwater river or stream meets the salt water of the ocean and creates brackish water
an area where a salt water in a river or stream meets the freshwater of the ocean and creates brackish water
an area where water becomes too polluted for use by living things
an area that is protected from pollution to support the maintenance of habitats in the area
Where is most of earths water?
lakes
ponds
ocean
Where is most of earths freshwater
glaciers and ice caps
rivers
groundwater
Excessive groundwater pumping can cause
zone of saturation
porosity
aquifer depletion
water table
What causes saltwater instrusion
When an aquifer drains into the ocean
When the zone of saturation overflows
When the porosity and permeability are too high
aquifer depletion on the coast which lets the salt water enter the aquifer
What are some threats to our groundwater
pollution
overuse
contamination from septic systems
all the these are threats to groundwater
Is it easy to remove chemical contaminants from groundwater
yes
no
How can out groundwater be protected and restored?
conserve water
reduce, reuse, recycle
maintain septic systems
all of these would protect our groundwater
Which of the following are important uses for freshwater
drinking water
sanitation
irrigation
all of these are important uses for freshwater
How could water use be different in different parts of the country
Some areas use more water for irrigation because they have more crops
All areas of the country have even distribution of people
Some areas have more access to saltwater which is used as drinking water
What are dams built for
to control water flow and flooding
to store water
to generate hydroelectric energy
all the these are reasons for building dams
Which of the following is the correct difference between point and non point pollition
Point pollution is the chemical entering the water way and non point happens when chemical mixing with another to create a new chemical
Nonpoint pollution is the chemical entering the water way and point happens when chemical mixing with another to create a new chemical
Point pollution comes from a single place and non point come from many places
Non point pollution comes from a single place and point come from many places
Storm water runoff is an example of
point
nonpoint
A leaking pipe is an example of
point
nonpoint
Which is easier to pollute
surface water
groundwater
Which of the following are factors that affect the water quality of streams
temperature, pH, runoff
transpiration, infiltration, pH
runoff, infiltration, deforestation
deforestation, temperature, pH
What is a biotic index
when water quality drop below a certain level
uses the number of organisms to indicate water quality
The organisms that live in an area
how is water treated to make it drinkable
Large particles are filtered out and then it is distributed
it is screened, filtered, and treated with chemicals such as chlorine and fluoride before distribution
All chemicals are removed and the water sent distributed is distilled
All the above are true about the treatment of drinking water
How can we conserve water
reduce
reuse
recycle
all of these
What is precipitation?
Sweat from our bodies on hot days
Warm rain but not cold snow or sleet
Gas that we use in furnaces or ovens
Any form of water that falls from the sky
What is another name or synonym for the water cycle?
Geologic cycle
Hydrologic cycle
Geosphere
Carbon cycle
What are formed when water vapor condenses?
Clouds
Mountains
Transpiration
Valleys
The movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat. ____________________
Evaporation
Convection
Precipitation
Transpiration
The act of turning from a liquid into a gas. ___________________
Transpiration
Condensation
Evaporation
Precipitation
The process where plants absorb water through the roots and then give off water vapor through pores in their leaves. __________________________
