Starting with the phrase 'high sea temperatures' use your knowledge and this diagram to explain the formation of a cyclone

High sea temperatures causes warm air from convection currents to rise, simultaneously causing a build up of energy and low pressure. This energy results in the powerful kinetic energy within a cyclone (with the help of latent heat.) The Coriolis effect then causes the cyclone to spin, as it is also the most energy stabilized way of movement

Temperate inversion

(i) where are strategies for reducing traffic emissions likely to be more effective - in developed world cities like los angeles or in developing world cities like Cairo and beijing?

Probably in developing countries like Beijing and Cairo, because they tend to emit the most greenhouse gases. Also, they may be more willing to 'go green' if they know it will save them money, unlike areas like los Angeles. 

(ii) state two reasons why atmospheric pollution are worse in places with a dry and hot climate

-In hot climates, the warm, less dense air mass moves over a dense, cold air mass. As a result, warm inversion layer then acts  stops atmospheric mixing, and traps the pollution

Accuracy: To increase accuracy/ get the number closer to it's true value, increase it's decimal points
Reliability: To make an experiment more reliable, repeat the experiment several times to eliminate anomalies
Drawing graphs: (example)

 

Burning Sugarcane is not environmentally hazardous

when you burn sugarcane, it does not contribute to the greenhouse gases.the sugar cane is acting as a carbon sink since the farmer is not burning a long-term storage of carbon dioxide. It's also sustainable since the carbon is taken in next year when the crops are grown again

20.6 - The nutrient cycling and carbon cycle
For nutrient cycling :

Nutrient cycling is a concept that shows how nutrients are being used up and given out by organisms and their environment


It is essential for life, and must remain both balanced and stable.

Text book pg 187
For carbon cycle:
Carbon is part of the nutrient cycle. 


We drew a mind map which shows the carbon cycles 

We listed the natural.. 
sources 

• Animals
• Volcanic eruptions

sinks

• Fossil fuels
• Plants/trees
• Oceans (note that the ocean both absorb and release CO2)
• Atmosphere

stations

• Animals
• Marine Biota
• Plants/Ancient plants
• Fossil fuels
• Oceans
• Atmosphere
• Soil

We played that dice game with the beads to get a better sense of how the carbon cycle works

It is also found in the text book pg 188
