Course Conclusions

Two General Course Goals:

1. To instill an appreciation of natural characteristics of the environment, and in particular, Earth's landforms, through an understanding the natural processes that shape these landforms

An introduction to the geographic contributions to environmental science: traditional fields such as geology, biology, botany, meteorology with a focus on the natural environment

2. To introduce you to some major environmental issues and concerns: in essence, issues that arise out of the intersection of the natural environment and human activities in that environment.

An introduction to environmental studies: involves basic understanding of natural processes, but broader: pull together elements from the diverse environmental sciences and add a focus on human relationships to and activities in the environment

Geography has always been a mixture of environmental science (physical geography) and environmental studies (environmental geography)

What we have covered this semester...

Introduction to Earth's Physical Environment

1. Defining Geography

2. Introduction to Earth's Physical Environment

3. Classifying the Natural World

4. Natural Cycles

5. Time and Space and Environmental Change

Introduction to Human Environmental Relations

1. Human Environmental Relations: Introduction

2. Human Environmental Relations: Examples

3. Human Perspectives on the Physical Environment

4. Human Forces Behind Environmental Issues

5. Human Induced Imbalances

6. Interest in Environmental Issues

7. Sustainable Development

Portraying the Earth

1. The Nature of Maps

2. Developments in Mapping: Computer aided Mapping

Introduction to the Atmosphere

1. Composition of the Atmosphere

2. Vertical Structure of the Atmosphere

3. Weather and Climate

4. Elements of Weather and Climate

Introduction to the Hydrosphere

1. The Nature of Water

2. The Hydrologic Cycle

The Process of Studying Landforms

Internal Processes: building up landforms

External Processes: breaking down landforms: forces in atmosphere + hydrosphere

Weathering, Mass Wasting, and Erosion

Denudation: disintegration, wearing away, and removal of rock material; implies a lowering of earth's surface

1. Weathering: processes that break up rock at the earth's surface

1a. A Typology of Cracks and Crevices in Rock:

1b. Weathering Agents

2. Mass Wasting: processes that move fragmented rock short distances down slope

3. Erosion

Fluvial Processes: any environmental processes involving the flow and movement of water on the Earth's surface

1. Impact of Fluvial Processes on the Landscape

1a. Traditional Theory of Landform Development: The Geomorphic Cycle

1b. Critique of Davisian Theory: Crustal Change and Slope Development

1c. Equilibrium Theory

2. Fundamental Definitions and Concepts of Fluvial Processes

3. Stream Channels: Key Characteristics of individual streams and rivers

4. Stream Systems: how streams and rivers relate to each other

5. Shaping and Reshaping of Valleys by Fluvial Processes

Karst and Hydrothermal Processes: Underground Water and Landforms

1. Karst Processes and Landscapes

Related to chemical weathering: breakdown and removal of rock due to chemical reaction between water and rock

Relatively widespread effect on earth's surface

1a. Solution and Precipitation

1b. Caverns and Related Features

1c. Karst Topography

2. Hydrothermal Features

In essence: underground water heated by magma then forced to earth's surface

2a. Hot Springs

2b. Geysers

2c. Fumaroles

Glaciers and Glacial Landforms

The role of ice, and in particular moving ice - glaciers - in shaping landforms

What we can see today in the landscape is the result of existing glaciers and the most recent ice age: the Pleistocene

1. Glaciers Formation and Flow

Overall result of glacial flow is a form of erosion by water

2. Mountain Glaciers (skip this section)

3. Continental Ice Sheets and Glaciers

3a. Development and Flow of Pleistocene Glaciers

3b. Erosion by Ice Sheets

...Transportation by glaciers...

3c. Deposition by Ice Sheets and Glaciers during Pleistocene

This course provides an overview of issues you can pursue in more advanced Geography and Geology courses at OWU:

Broadest Goals of Course:

Appreciation that our environment is dynamic and constantly being modified by natural processes and human activities.

Basic understanding of the natural processes

Basic understanding of human induced changes in the environment, why they occur, their impact, and complexity

Heightened awareness of the complexity and importance of the environment we live in and depend upon in so many ways. Basis for a lifelong appreciation for, and concern about, the Earth's environment.
