References and Introductions

Hello,

The following blog was comprised as part of a Geography 201 Spring course focussing particularly on Physical Geography. Photos not taken by myself are credited and the book Physical Geography: The Global Environment by H.J. de Blij was used as a source of reference and detail. For more in regards to referencing and sources, please feel free to contact me. I hope you enjoy the blog!

Chapter 3: Mapping the Earth's Surface

Geocaching, GPS & Global Mapping


Geocaching is a game of sorts wherein an item is placed at a specific destination and then the coordinates are given to a different party for the purpose of them eventually discovering that location. GPS’s come in handy here as the coordinates are fed into the device and specific points of the mystery item are given out and made able to track. As a device, the GPS is now widely available, expanded from its original use strictly by government personnel, the military and scientists. Now most cars come with the device built-in, and remarkably, the system connected to more than twenty four satellites orbiting the Earth is compacted and at ready disposal of the majority. This picture was taken during a field trip taken to geocach as a class, and although a bit hard to see, I am holding the green capsule from the day.    

Chapter 4: Earth's Setting in Space

To Infinity...and Beyond!






Like the Greeks before us, human beings remain astounded by moving celestial bodies, planets, and many space expeditions are conducted still with the hope of discovering more about these revolving bodies part of our solar system. The image with me in is of our Milky Way galaxy, believed to have been formed more than twelve billion years ago. Simply said, man is fascinated by space, or rather, the idea that more exists beyond the literal horizon. With all the effort thrown into space exploration and planet study, it is little wonder that the perceived solution to Earth’s depleting resources lies somewhere in space.   



Chapter 5: Composition and Structure of the Atmosphere

Put the Kettle On


The kettle boiling is releasing steam into the atmosphere, and this translucent water vapour in turn then evaporates. Although invisible, this gaseous form of water both stores and absorbs energy and is transported by air currents, taking with it stored energy. This process, the movement of water vapour, is essential in moderating surface temperature, thus making it appropriate for humanity's habitation.

Chapter 7: Atmospheric and Surface Temperature

Say NO to Smog.






Smog is the backdrop to most industrialized economies. Factories produce large amounts of heat and release this energy, along with harmful chemicals burned by the plants, into the atmosphere. In most cases this is done on a daily basis, and in cities like Edmonton, a cloud of grey industrial smoke covers the tops of buildings and industrial plants. The release of smog is a form of pollution in the atmosphere causing higher levels of ground-level ozone and consequent depletion of the ozone layer. As we continue to search for more renewable resources, the smog enveloping most of our bustling cities serve as deadly reminder to the hazards the Earth faces if more by way of conservation efforts is not done.    



Chapter 8: Air Pressure and Winds

Blame it on the Coriolis






The Earth rotates, and this movement affects direction of atmospheric circulation, the most essential effect being expressed as an outward deflecting force. Coriolis, the deflective force, in the absence of other forces deflects moving objects by hemisphere, the right being north and left in the south. Winds travelling from the North Pole then become easterlies as they are deflected right, and as a whole, Coriolis plays an important role in deciding general patterns of atmospheric circulation. 



Chapter 9: Circulation Patterns of the Atmosphere

Nature Puts Up a Good Front






























As the atmosphere works to redistribute heat and moisture throughout the Earth’s surface, air travels from areas of high to low concentration. Climates are controlled by intricate reactions between these atmospheric circulation as well as movement and properties of oceanic waters. The surface circulation model seen in this picture is obviously idealized; hence the actual design is decidedly more multifaceted.
