What is produced when fuel is burned and oxygen is blocked from reaching the burning fuel. In severe cases, breathing carbon monoxide can result in suffocation.
Carbon Monoxide
100
What is an air pollutant that is created when certain chemicals (nitrogen dioxide and VOCs) mix with sunlight. These chemicals are created by burning fuels such as the gas and oil used in vehicles.
Ozone
100
Plant and animal matter decay and break down to create what? is also called humus. It is the part of soil that has the most nutrients and can be found in compost.
Organic matter
100
What are the two main negative impacts of human activity on soil
Pesticides and invasive species
100
What color of soil indicates best quality?
Dark brown soil contains more organic matter and so is healthier. Lighter grey-brown soil contains less organic matter and is poorer in quality. Poor soil, on the other hand, tends to contain more gravel, sand, or clay.
200
What component is caused by moisture and lack of air circulation, can result in a variety of symptoms, such as headaches, coughing, and fatigue.
Mould
200
A gas produced when the element sulphur is burned. is created in smelters and factories. mixes with water and causes acid rain. High levels of this can cause breathing difficulties.
Sulphur dioxide
200
Rock gets broken down by wind, water, and chemicals to create small particles of mineral and rock. These make up what?
Inorganic matter
200
Which bin improves soil quality and can include:
- fruit peels
- leftovers
- coffee grounds and filter
- tea bags
compost (the organic contents of green bins) improves soil quality.
200
What refers to the organic content in soil? Testing this will give you a more precise measure of the amount of organic material present rather than simply observing soil colour or feeling its texture.
Humus
300
What are gases released from manufactured materials (often found in rugs and drapes, for example) over time. Symptoms vary with the particular VOC but can include fatigue and a variety of allergic reactions.
Volatile Organic compounds
300
What refers to the small particles - dust, pollen, smoke, and fumes - in the air. Almost all manufactured fine particulate matter is created by the burning of fossil fuels such as coal, gas, and oil in vehicles and industrial plants
“fine particulate matter”
300
2 things that are needed by all plants and animals. They produce energy and help plant roots to grow.
Air and water!
Water is used by all living things to execute many functions, such as producing energy. Air allows water to flow through soil and plant roots to grow.
300
Which bin do these items go into?
- plastic bottles
- milk carton
- yogurt container
Container recycling bins
300
These organisms (examples: small animals and insects) living in the soil that can be observed without a microscope. specifically these organisms are found in soil that contains the organic matter they need for nourishment. They also improve soil quality by creating little tracks and holes in the soil. This allows both air and water to get into soil.
Macro-organisms and earthworm content
400
Which gases is air made up of
Air is made up of nitrogen (78%), oxygen (21%), water vapour (less than 1%), and traces of argon and carbon dioxide.
400
Gas that is created by combustion in vehicles and, to a lesser extent, factories. It is one of the sources of ozone. This reddish-brown gas can irritate lungs and prevent the body from fighting infections in the respiratory system.
Nitrogen dioxide
400
The 4 parts of inorganic matter
- gravel
- sand
- silt
- clay
400
Which bin contains the following:
- plastic package
- tin foil
- bubble wrap
Trash or garbage
400
What type of ph is optimal for soil
6-8
500
What are the 3 pollutants of air
- ground-level ozone,
- fine particulate matter, and
- nitrogen dioxide

What are the 4 soil components
- organic matter
- inorganic matter
- water
- air

what is this diagram show?
A graphic diagram depicting the closed loop cycle of Toronto's organic waste management system. The cycle unfolds in six steps, beginning with
Step 1 the production of organic waste.
Step 2 is when collection occurs.
Step 3 is when the anaerobic digestion process unfolds.
In Step 4, biogas is upgraded to renewable natural gas.
Step 5 is when that renewable natural gas is injected into the grid.
In step 6, natural gas is converted to its end use as heat, electricity and fuel.

What soil density is best for soil that allows for best water percolation
Not too porous and not too dense
