Time flies really fast doesn't it? Well, that's a good cause MR HEAH IS BACK!!!!!! :DDDDD
so basically here are the things we have learnt throughout the term
Key Learning Points
1) How different things interact and work together to form a system
2)Balance is essential in every system
e.g. Thermodynamic equilibrium
Sara's example: Carbon dioxide, too little and we will freeze to death, too much and we will have global warming.
Its ironic that we are messing up the very balance that is keeping us breathing
3)
Structure and composition of the atmosphere
-Nitrogen: 78%
-Oxygen: 21%
-Carbon Dioxide: 0.03%
-Other gasses: 0.97%
4) Importance of the atmosphere
-Block out UV rays
-provides oxygen
-keeps the Earth warm
5) The classic "place shapes people, people shapes place",that we have been learning since last year. Let's name this Heah's law :D
e.g. eskimos adapting to live in the cold
6) Global warming
WE HAVE TO DO SOMETHING ABOUT THIS PEOPLE!!!
7) The different types of rain, how do they occur and when do they occur.
-Relief (contributes to the formation of deserts)
-Frontal
-convectional
(adiabatic cooling is involved in all of the above)
8) Climate and weather
These 2 can always be seen as how warm and how wet a place is and is also dependent on its latitude and longtitude.
9) How to read a climograph
Apart from reading from the graph, we would also have to interpret the data or else all those numbers would just be useless.
10) Seasons and its relevance to the tilt and shape of the Earth
(refer to Minh's post dated February 23rd, very detailed)
11) How winds move
-The 3 cells (Hadley, Farrell and Polar)
12) Deserts
To clear up a common misconception, deserts are not formed where it is very warm, but rather where it is extremely dry. This can be expained byt the direction of winds which carry the water vapour which ultimately results in percipitation. :D
-Formation can be explained by tricellular model or relief rain
13) Drainage basin
-What happens to percipitation (Infiltrate, throughflow, baseflow, interception, throughfall, stemflow etc)
14) Hydrographs
-How to read them
-Its use (to predict the chances of flooding and how authorities have to evacuate the people before it starts to flood, or before the situation worsens)
In this case, the lagtime is very important to determine how much time they have to evacuate
-The factors which affect the shape and height of the hydrograph (shape,size, geology, etc)
15) River processes
-Transportation (the different types of loads)
-Erosion
16) Braided channels and deltas
17) Meanders
caused by -Diff velocities at diff parts of river
- Helicodial flow
How it can result in an oxbow lake
LIFE SKILLS
BE CONCISE
NEVER MEMORISE, UNDERSTAND
BREAK DOWN QUESTIONS
ITS ABOUT THE QUESTION NOT THE ANSWER
