Earth Science Processes Photo Essay - Papers Due the Day of the Final Exam 40 Points, 10 Photographs, 10 Paragraphs The Earth Science processes discussed in class are not only found in exotic locations, but in our own immediate environment. Being able to recognize physical processes in the landscape is an important goal in this course. The purpose of this assignment is for you to practice your skills of geographic observation within your own community by applying concepts and topics that we cover in class and Southern California. You will want to be mindful of Southern California's particular geography in your discussion of the topic. Remember – the purpose of your photo essay is to illustrate and describe the unique physical features and processes in Southern California. Don't take a picture of dew and say “It's humid”. I know that, why did the dew form, what is it telling us? Topics: 1. Temperature Inversion Layer OR Lifting Condensation Level (LCL) The inversion layer is unpredictable more than a day or so out bring your camera with you when you are out and about. LCL is common at times when inversions are not. You need to capture one or the other. 2. Earth Sun Relationships Take a photograph of something with shadows and explain why and how the shadow length will vary throughout the year. Please note that this concept is not the same as day length. 3. Humidity Either high or low humidity. Explain what humidity is. 4. Atmospheric Lifting Mechanisms There are four types though we don't get Convergent. Orographic lifting is easy & close too. 5. Weather Describe the weather for a particular day – include newspaper or online weather information for date. What were the contributing factors to that day's weather? 6. Climate How does the native vegetation reflect Southern California's climate. Don't take a picture of roses or palm trees for this topic. Those plants are not native to Southern California. 7. Earthquakes Earthquake preparation will suffice since we cannot predict an earthquake this semester. Do not just take a picture of a crack in the ground and say “earthquake”. Why do we need to prepare for earthquakes in OC? 8. Stream processes Not just a pretty picture of a stream, I want a process, transportation, erosion, bed load… 9. Coastal processes - Headland 10. Coastal processes – your choice Not just a pretty picture of the beach, I want a process: wave erosion, sea stacks, spits, tombolos, Requirements: -10 Photographs, 10 Paragraphs -Photos are limited to Southern California. If you have pictures that you really want to use that were taken in locations other than Southern California let me know about it in advance. Photos should be at least 3x5 in size. -Include a table of contents. Your photos should be in the order shown above. -Each photo will have a typed description and paragraph analysis (see below for example). Bibliographic information will include the location, date and time of photo. The analysis will include a definition or explanation of the topic and a detailed description/analysis of how the photo represents the topic. The more insightful the analysis the higher the project grade. -Please put enough of an effort so the glue does not stick the pages together, your printer has ink, etc... Do not put pages in plastic sleeves. A fancy scrap booking project will not help your grade. Please put that effort into the descriptions instead. Staple the 11 pages together. Failure to bind your project together will have a negative impact on your grade. All essays will be graded on the following criteria: -Photos are neatly & clearly presented including all data & descriptive information. -Follow instructions, format follows the sample given below & includes a table of contents. -A variety of topics from class are illustrated from a variety of locations. -Analysis is insightful and clearly related to information covered in class. -Appropriate terminology is defined. Sample Photo Analysis: Topic: Mass Wasting Date: October 3, 2009 Location: Ortega Hwy Description: Landslide Analysis: Ortega Highway cuts east out of Orange County through the mountains and along the way the slopes are steep and subjected to mass wasting. The material tumbled down the slope in a process known as a landslide. Recent rains would have lubricated and added weight to the slope though there was apparently limited mudflow in this event. Road cuts may have also steepened the slope encouraging mass wasting. This landslide was a quick event (as opposed to creep) and will be quickly cleared by CalTrans. One can assume though that given the steep slopes along Ortega that this event my likely re-occur. Good thing I am not commuting through here… source..

Earth Science Processes Photo Essay Name Institution of affiliation Earth Science Processes Photo Essay Topic: Temperature Inversion Layer  Date: Location: Description: temperature inversion Analysis: In a typical situation, the atmosphere becomes cooler as the elevation increases. A temperature inversion occurs in the troposphere when a layer of warmer air overlies a layer of cool air at the surface. Inversions affect the formation of clouds, smog, and precipitation. When inversions occur, diffusion of pollutants including dust and smoke is limited. Fog is formed because the air near the base of an inversion is often cool. The picture shows the effects of temperature inversion where the bridge has limited visibility. The smog and fog pose dangers on road and air transport. Temperature inversions also influence the diurnal temperature variation because only a shallow layer of air is heated on the ground level to cause an exchange of heat with the upper levels. Topic: Earth Sun Relationships  Date: Location: Description: Shadows Analysis: The sun is the source of energy and light during the day. The shadows formed by stationary objects changes in length throughout the year. Measuring the length of the shadow from fall to spring, one notices that it becomes longer as the fall progresses. The shadows are at their longest length during the winter solstice, and they become shorter as spring approaches. The picture depicts a phenomenon where the shadow length show that its summer. The length of the showdown is influenced by how the earth revolves. The changes in the angle of the earth to the sun determine the length of the shadow and the season in a particular area. . Topic: Humidity  Date: Location: Description: high humidity Analysis: Humidity refers to the amount of water vapor molecules in the air. The water vapor refers to the gaseous state of water that can be seen with the eyes. The picture shows a condition of high humidity that has condensed on a glass surface. High humidity is a sign of the likelihood of precipitation, dew, or fog. Humidity influences many biological aspects including development of disease-causing microorganisms in plants and animals. Fundamentally, it affects how the human body responds to heat regulation through sweating. When the humidity is high, there is reduced evaporation limiting heat exchange between the lower and upper atmosphere. Consequently, the air becomes cold, especially at night. Topic: Atmospheric Lifting Mechanisms  Date: Location: Description: orographic lift Analysis: There are various causes that can make the air move vertically. Orographic lifting occurs when barriers such as mountains and hills on its path causes the upward motion of air. The orographic lift can cause clouds and precipitation. The picture shows that the upward movement of air caused by the mountain has sufficient amount of moisture to reach condensation. The air cools as it blows up the mountain on the windward side and forms clouds that fall as rainfall. Often, the vertical mo...
