Hello everyone!

Here's the summary post.

So we started this module looking at the big picture, the atmosphere.
We studied the many layers of the atmosphere, the composition of air in the atmosphere as well as some of the important cycles that take place around us - the carbon cycle and the nitrogen cycle. We also learnt about the ozone layer, and its importance in sustaining life on Earth.

We then studied the importance of the Sun, and learned about the Planetary Heat Balance, which ensures a steady level of heat on Earth. We learned how the heat was divided up into longwave and shortwave radiation, and the proportions in which it is divided. We also learned about seasons, and how they are formed by the revolution of the Earth around the Sun.

We then moved on to air and wind, where we learned the 3-cell model and different wind patterns. We observed the model's relation to the formation of natural features, such as deserts. We also started learning about climates here, and the many different kinds of climates that exist. We also learned how to analyse a climograph, and to describe the climate of an area with regard to the level of precipitation, and temperature range.

We ended the Atmosphere section with the study of clouds and rain. We learned the formation of clouds by adiabatic cooling, and the 3 kinds of rain that exist. The concept of clouds and rain also provided a base from which to begin the Hydrosphere half of the module.

The hydrosphere half was certainly content-heavy. We started with the study of the water cycle. This is something all of us were familiar with from primary school, but now, we learned the more in-depth terms used to describe the various processes, such as interception, percolation, and throughflow. We studied the flow of water from the time it is precipitated as rain or snow, to the time it joins the river channel to be carried to the sea. We then moved on to the water balance equation and hydrographs, both of which enable us to see the changes in the amount of water flowing in a river. We then observed how changes made by humans could affect the water balance equation and hydrograph of a river. We studied the changes made by the introduction of agriculture, urban features as well as deforestation.

We then moved on to the study of the rivr itself. We studied the characteristics of the upper, middle and lower course of the river, noting the shape of the channel, velocity of the water as well as the processes that occur at the specific areas. With the knowledge of the processes of erosion, transportation and deposition, we were then able to understand how specific features such as waterfalls, meanders, floodplains and deltas are formed at the specific areas of the river.

With that, we end our module, with a project remaining for us to present after these holidays. The project, involving river management, will certainly help us realise how significantly human activity impacts the river and its contents.

So there's a short (HAHAHA) summary of this module!
