Eutrophication is caused by
excess nutrients building up in the water.
industrial point-source pollution.
unlined landfills and septic tanks.
wastewater from homes mixing with drinking water.
How does eutrophication cause the death of aquatic organisms
the build up of carbon dioxide in the water
the lack of nitrogen in the water
the lack of carbon dioxide in the water
the lack of oxygen in the water
The two critical nutrients in eutrophication are... (select two)
nitrates
phosphates
carbon dioxide
dissolved oxygen
A new golf course is built next to a river. Over the past several months, the nitrate levels of the water in the river have been increasing. Which best explains the cause of the increasing nitrate levels?
increased growth of algae
decreased biodiversity
runoff from fertilizer
chemical reactions with pesticides and fertilizers

What is the hydrological cycle?
the transformation of water from liquid to solid, solid to liquid, gas to liquid and liquid to gas
the movement of water between atmosphere, lithosphere, biosphere and pedosphere
the movement of water through the soil as infiltration, into surface water as run-off and into the atmosphere as it evaporates and back as precipitation after condensing
precipitation, run-off, evapotranspiration and oceans
Of the 15 water scarce countries, 12 are in...
United Kingdom and Canada
America and Canada
Southwest Asia and North Africa
Russia and Germany
A process that removes salt from the ocean water.
desalination
hydroelectricity
irrigation
fossil water
Which answers are below are the reasons for unequal distribution?
Being rich or poor
There is no modern plumbing access to water
fresh water access due to contaminated water and walking many miles to water source
Water is often wasted for building projects and irrigation
All the above
Water pollution and waste have a large effect on water shortage.
True
False
What is the term used to describe an area that begins to have more desert like conditions.
Steppe
Wadi
Desalinization
Desertification
Why is desalination not a practical process for water usage?
No one knows how to do it
It is too hard
It is too expensive and not practical to meet all region's needs
It cannot be used in some countries for religious reasons
Where is most water found on the Earth?
In Glaciers
In Lakes
In Rivers
In the Ocean
What is an underground store of water in permeable rock?
sewage system
aquifer
precipitation
irrigation
Where is most of the freshwater found on Earth?
lakes / rivers
ice caps / glaciers
oceans / seas
rivers / streams
Approximately what percentage of the water on Earth is freshwater?
0.1%
2.6%
50%
97%
The flow of water across the land surface into a body of water.
groundwater
headwaters
run-off
infiltration
What is infiltration?
How you get into clubs with fake ID
Groundwater flow through permeable rocks into bodies of water
The movement of water into the vegetation and into cells of living organisms
water soaking into or being absorbed by the soil
The diagram shows currents distributing the temperature around the Earth but what is it called?
The Great Ocean Roadway
The thermocurrents redistribution
The Great ocean conveyor belt
The big temperature exchange
The warmer water currents are surface currents, this is because...
The warmer water holds less carbon dioxide
The warmer water is less dense
The warmer water holds more carbon dioxide
The warmer water is more dense
As the heat entering the Biosphere is moved from the equator (high insolation) towards the poles, the colder water...
Travels down to replace warmer water as "downwellings"
Travel up to replace the warmer water as "upwellings"
Holds more salt so is denser so is in the deeper parts of the ocean
Carries nutrients from decomposing organisms at depth to provide nutrients for phytoplankton at the surface
Holds less salt so is less dense and is in the shallows of the ocean
High specific heat capacity of water means that the oceans change temperature more slowly, this affects land close to oceans
Severe winters and very hot summers
Severe winters and cool summers
Moderate winters and cool summers
Moderate winters and very hot summers
Humans can affect the hydrological cycle by speeding up the flow of water, which of these activities has this effect?
Building cities
Straightening rivers into canals or pipes
Making reservoirs by building dams
Using water for irrigation
Deforesting areas
Increased flash flooding occurs because less water can infiltrate the soil after precipitation, which of these human activities makes this problem worse?
Overgrazing and trampling soils
Deforestation
Burning fossil fuels
Building roads and buildings of concrete
Releasing pollutants into rivers
What is advection?
when water soaks into soils
when water soaks through soil or rock into aquifers
wind-blown movement of water in the atmosphere
water which flows over the Earth's surface
What is percolation?
when water soaks into soils
when water soaks through soil or rock into aquifers
wind-blown movement of water in the atmosphere
water which flows over the Earth's surface
