Study guide for Exams Be able to answer the questions from the study guide for the exam. I will not collect the answers. I usually answer these questions in our lecture. So…..TAKE NOTES beyond what is written on the screen. Study,study,study…flash cards, reading your book, write out answers to the questions. Each week and when an exam comes along. Have enough depth in your answers. My questions are general and may cover a lot of material. Focus on these questions for the exam. You text covers a lot of material I provide the study guide for a reason.

Study Guide for Exams Chapter 1 1. State the definition of a system. Give examples of a system. 2. Identify and describe the four major divisions of our Earth system. How do each of these systems overlap? 3.Define and give examples of an open system and closed system. 4.Define pollution. What are some causes of pollution? 5.List two careers open to a student with a degree in geography. What does it mean to think globally but act locally. 6.What is a model? Describe the four different types of models. What are examples of each of these models?

Taking notes More than what is on the screen. Printing out notes.

What is Geography? Geo= earth Graphy= picture or writing. Describes, examines, and explains the Earth. Geography is about asking questions and solving problems. Making connections between people and places. Relationship between people and the environment. It is a combination of a natural and social science.

The Big Picture Geographic knowledge demonstrates not only differences but similarities as well We study geography to know ourselves and our place in the world and also to understand the processes of the place where we live Who would we be if we had no sense of place?

What is Physical Geography? Study of Earth’s systems/Earth’s major divisions : –biosphere –lithosphere – atmosphere, – hydrosphere Answers how Earth’s systems function.

Systems A system maybe thought of as a set of parts or components that are interrelated through space Variables Examples? Earth System- how do the variables combine to make our home? Mountain positions affecting rainfall Variation in rainfall affects distribution and types of plants. Earth systems are dynamic, always changing

Major Divisions of the Earth System Atmosphere Lithosphere Hydrosphere Biosphere How do these Earth systems overlap?

Pollution and Models Pollution is an undesirable or unhealthy concentration of a contaminant in an environment as a result of human activity. What do you consider the worst pollution threat? Models?

Models There are 4 different types of models we study. –Physical model i.e. a globe –Pictorial or graphic model i.e. maps, graphs –Math/ statistical models to predict flooding –Conceptual model – in our mind.

Open System Energy - Matter Interactions Energy Output Matter Output Energy Input Matter Input Fig Examples? The major divisions/systems of Earth. Lithosphere, hydrosphere,atmosphere,biosphere

Closed System Energy - Matter Interactions Matter is contained within the system boundaries Energy Input Energy Output Fig 1.19 Example? Earth

Careers Careers open to someone studying geography –Meteorologist –GIS specialist –Planner –Water Resources manager

Ecosystem An ecosystem is a community of organisms and relationships of those organisms to their environment. Depends on scale. As small as your backyard or as large as a national park.

Discussion Pair/Share Answer the following questions yourself. Pair up and discuss. Share with class. How have ecosystems in your city been affected by human activity? Good or bad. What does it mean to think globally but act locally? How have various kinds of pollution affected your life? List some sources of pollution in your city or town. What do you consider the most important pollution threat to the Earth.
