Final Exam Monday May 9th 3-5P.M Geog 2051 Geography - the study of space distribution of Phenomena. How things are arranged. Old Geography what is where? Description, writing about places and what they are related too (Simple curiosity, survival instinct, political power, economy, cultural reasons). New Geography why? Explain why things are the way they are. Understanding the way things are. Aspect on how the world works and it operates. Four Shapes of Geography – Physical – 1) Lithosphere – Solid earth (Geomorphology) 2) Hydrosphere – Water (water resources) 3) Biosphere - Living 4) Atmosphere – gases 5 common Themes in Geographic Research 1) Location – study of where things are arranged 2) Place – characteristics that makes a location unique (New Orleans) 3) Region – Characteristics that shares locations with others or are the same 4 ) Movement –networks, pathways, interconnections 5) Human Earth relationships – People impact on environment (pollution) Chapter 1 Methods and Tools - Scientific Method – Creating Knowledge, hypothesis (educated guess), and theory (generally accepted knowledge) - Image of World, A priori knowledge - 1st Step: Formulating Hypothesis - 2nd Step: Evaluate the Hypothesis (Test), fundamental nature of truth. Disprove a Hypothesis. Can never PROVE truth! - Systems Theory - A group of concepts that represents reality - A group of objects (elements, characteristics that are linked together by flows of matter of energy) - System – Closed (can't enter or leave), Open (moving energy that can leave and enter). Earth is an open system. BOOK IS LYING!!!!!! All natural systems are open - Budget – Inputs of matter energy, Outputs of matter energy and change (difference) of storage. Inputs are larger than outputs the storage is going to increase (positive). Outputs are larger than Inputs the storage is going to decrease (negative). If the Input equals to Output the storage is the same and is called Equilibrium. - Static Equilibrium – storage doesn’t change - Dynamic Equilibrium – constant change of storage Ex: (grass -> mice -> wolves during wet times and dry times) The biomass is increasing and decreasing during wet and dry times. A balance between all components. - Lag period – time between sun change and system responsible. - Feedbacks (positive, negative) – System responses to some change of environmental conditions that acts to influence of original change. Positive feedbacks (Snowball effect) enhances increasingly change. Positive Feedbacks tend to be destructive. Negative feedbacks dampen decreased change.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
