When water flows over porous soils

overland flows soak through easily to the groundwater

carbon is released to the atmosphere

To decrease their reliance on chemical fertilisers dairy farmers

use their cows manure as fertiliser on the fields

The clearing of native forests

increases water flows to the river

Fossil fuels are so called because they

take hundreds of millions of years to form

European settlement on the Dorrigo Plateau first occurred in

the late 1880s, mainly by timber cutters

Rainforest soils are generally not very fertile because decomposers breakdown matter & release

nutrients to be taken up by the root systems of trees

The four spheres that make up the biophysical environment are the

lithosphere, hydrosphere, biosphere and atmosphere

Urban development affect catchments through

increasing water flows to the river

The soils beneath Dorrigo National Park

were deposited by a volcanic eruption 18 million years ago

Fossil fuel combustion

releases carbon in the atmosphere

Dairy farmer, Alan Jarrett, has to import the nutrients phosphorus, potassium & sulfur because

of the break in the rainforest nutrient cycle

Ships are unable to travel far up the Bellinger River because

so much sediment has been deposited on the riverbed

Since industrialisation

human activities have increased CO2 levels

The cryosphere refers to

freshwater locked up in ice sheets and glaciers

Questions 30

Answers

1
When water flows over porous soils
all of the other responses
it picks up large amounts of silt and clay in suspension
drainage is impeded
overland flows soak through easily to the groundwater
2
Most carbon is stored in the
atmosphere
biosphere
lithosphere
hydrosphere
3
When volcanoes erupt
lava spills out through fissures into the hydrosphere
carbon is stored in the lithosphere
pulverised fragments of rock are released to the cryosphere
carbon is released to the atmosphere
4
To decrease their reliance on chemical fertilisers dairy farmers
change to growing avocado trees
use permaculture techniques
use their cows manure as fertiliser on the fields
stall feed their cattle
5
Burning fossil fuel releases carbon into the atmosphere in the form of
chloroflurocarbons
methyl hydrates
calcium carbonate
carbon dioxide
6
Water is cycled back up into the atmosphere through
all of the other responses
evaporation and precipitation
transpiration and precipitation
transpiration and evaporation
7
The clearing of native forests
increases water flows to the river
increases the likelihood of drought
decreases water flows to the river
decreases the likelihood of drought
8
Fossil fuels are so called because they
always contain impressions of plants and animals
are incapable of further change
are mined through burrowing into the earth
take hundreds of millions of years to form
9
European settlement on the Dorrigo Plateau first occurred in
the late 1960s, mainly by hippies
the late 1880s, mainly by timber cutters
the late 1930s, mainly by dairy farmers
the late 1780s, mainly by timber cutters
10
The sample study of the coast and the carbon cycle is an example of the cycling of carbon at a
global scale
local scale
national scale
continental scale
11
Shells are made from
calcium carbonate
all of the other responses
dolerite and gneiss
mica, quartz and feldspars
12
The amount of accessible freshwater in the hydrosphere is
less than 1%
less than 20%
less than 15%
less than 10%
13
Rainforest soils are generally not very fertile because decomposers breakdown matter & release
nutrients to be taken up by the root systems of trees
nutrients to the soil from organic matter
nutrients to the atmosphere as a gas
all of the other responses
14
Decomposers break down matter and release nutrients to
the atmosphere as a gas
be taken up by the root systems of trees
the soil from organic matter
all of the other responses
15
The biosphere is the zone around the earth
containing gasses
containing continental and oceanic crust
containing water
where all life exists
16
The atmosphere is made up of
one different level
three different levels
two different levels
four different levels
17
The four spheres that make up the biophysical environment are the
lithosphere, hydrosphere, cryosphere and geosphere.
geosphere, ecosphere, biosphere and lithosphere
lithosphere, hydrosphere, biosphere and atmosphere
cryosphere, lithosphere, atmosphere and ecosphere
18
Urban development affect catchments through
decreasing water flows to the river
increasing water flows to the river
increasing the likelihood of drought
decreasing the likelihood of drought
19
The soils beneath Dorrigo National Park
formed under coniferous forest ecosystems
were deposited by a volcanic eruption 18 million years ago
are best described as mellow textured duplex soils
are stony and infertile
20
Fossil fuel combustion
refers to the burning of tropical forests
takes place in nuclear power stations
fixes carbon in the lithosphere
releases carbon in the atmosphere
21
Ecosystems
must be 10 square kilometres in size
are at least the size of a billabong
are continental in scale
can be of any size
22
Dairy farmer, Alan Jarrett, has to import the nutrients phosphorus, potassium & sulfur because
grass won’t grow in the winter season
of government subsidies on superphosphate
dairy cattle need these nutrients in their feed
of the break in the rainforest nutrient cycle
23
Dorrigo National Park rainforest is an example of the nutrient cycle operating at a
continental scale
national scale
global scale
local scale
24
The sample study of the Bellinger River catchment is an example of the cycling of water at a
global scale
regional scale
national scale
continental scale
25
The carbon cycle reveals that phytoplankton growing in the oceans takes in
nitrogen and releases carbon
carbon and releases oxygen
carbon and releases nitrogen
oxygen and releases carbon
26
Ships are unable to travel far up the Bellinger River because
too many bridges impede their passage
the river is too narrow
so much sediment has been deposited on the riverbed
the river currents are too swift and unpredictable
27
Catchments function as a result of interactions between
water and climate
gravity and topography
all of the other responses
soil types and vegetation
28
Since industrialisation
CO2 levels have stayed the same
human activities have decreased CO2 levels
human activities have increased CO2 levels
29
The lithosphere is split up into many parts called
subduction zones
fault zones
tectonic plates
volcanoes and earthquakes
30
The cryosphere refers to
an internal section of the lithosphere
freshwater locked up in ice sheets and glaciers
the coldest part of the biosphere
the upper part of the atmosphere
