Fossil fuel combustion

releases carbon into the atmosphere

Since industrialisation

human activities have increased CO2 levels

When water flows over porous soils

overland flows soak through easily to the groundwater

Fossil fuels are so called because

they take hundreds of millions of years to form

Trees and shrubs, The atmosphere, In the oceans

the zone around the earth where all life exists

Organisms depend upon these to grow

all of the ablve, air, nutrients, water

The clearing of native forests

increasing water flows to the river

The four spheres that make up the biophysical environment are:

the lithosphere, hydrosphere, biosphere and atmosphere

The cryosphere refers to

freshwater locked up in ice sheets and glaciers

Urban development affect catchments through

increasing water flows to the river

Answers

1
Fossil fuel combustion
takes place only in nuclear power stations
fixes carbon in the lithosphere
refers to the burning of tropical forests
releases carbon into the atmosphere
2
Since industrialisation
CO2 levels have stayed the same
human activities have increased CO2 levels
human activities have decreased CO2 levels
3
Shells are made from
fish and chips
dolerite and gneiss
calcium carbonate
mica, quartz and felspars
4
The lithosphere is split up into many parts called
subduction zones
tectonic plates
volcanoes and earthquakes
fault zones
5
The amount of accessible freshwater in the hydrosphere is
less than twenty per cent
less than ten per cent
less than fifteen per cent
less than one per cent
6
When water flows over porous soils
overland flows soak through easily to the groundwater
it picks up large amounts of silt and clay in suspension
drainage is impeded
all of the above
7
Fossil fuels are so called because
they are mined through burrowing into the earth
they always contain impressions of plants and animals
they are incapable of further change
they take hundreds of millions of years to form
8
Carbon is stored in
Trees and shrubs
The atmosphere
In the oceans
None of the above
9
The biosphere is
the zone around the earth where all life exists
the zone around the earth containing gasses
the zone around the earth containing water
zone around earth containing continental, oceanic crust
10
Organisms depend upon these to grow
all of the ablve
air
nutrients
water
11
The clearing of native forests
decreasing the likelihood of drought
increasing the likelihood of drought
decreasing water flows to the river
increasing water flows to the river
12
Burning fossil fuel releases carbon into the atmosphere in the form of
methyl hydrates
carbon dioxide
calcium carbonate
chloroflurocarbons
13
The four spheres that make up the biophysical environment are:
the geosphere, ecosphere, biosphere and lithosphere
the lithosphere, hydrosphere, cryosphere and geosphere
the lithosphere, hydrosphere, biosphere and atmosphere
the cryosphere, lithosphere, atmosphere and ecosphere
14
The cryosphere refers to
the upper part of the atmosphere
freshwater locked up in ice sheets and glaciers
the coldest part of the biosphere
an internal section of the lithosphere
15
The atmosphere is made up of
four different levels
three different levels
two different levels
one different level
16
Catchments function as a result of interactions between
gravity and topography
soil types and vegetation
all of the above
water and climate
17
Ecosystems
must be 10 square kilometres in size
can be of any size
are at least the size of a billabong
are continental in scale
18
Urban development affect catchments through
decreasing the likelihood of drought
increasing the likelihood of drought
increasing water flows to the river
decreasing water flows to the river
19
Water is cyled back up into the atmosphere through
transpiration and evaporation
all of the above
evaporation and precipitation
transpiration and precipitation
20
Decomposers break down matter
All the above
releasing nutrients to the atmosphere as a gas
and release nutrients to be taken up by the roots of trees
and release nutrients to the soil from organic matter
