Using your knowledge of adiabatic processes explain the movement and modification of a parcel of air as it moves up the windward side of the Olympic Mountain (step 1) on the diagram below. Your description must include meaningful use of the terms; adiabatic cooling or adiabatic warming, windward or leeward, LCL, DAR, SAR. (Very Important: Your response must demonstrate an understanding of adiabatic processes. The response should also exhibit good sentence structure, avoid grammatical errors, and be without superficial responses. Superficial responses that do not show a grasp of adiabatic processes will not receive any points). Need help with the basic facts? Study the PowerPoint notes for this lab and the tutorial "DAR and SAR".

Adiabatic processes are processes of cooling or warming without gaining or losing heat. In this image, the windward side is the left side as that is where the air mass is coming from. The windward side is where the cloud is located, which is typical of windward sides as they usually have more precipitation than leeward sides. Since the left side is the windward side, the right side is the leeward side. The leeward side faces away from the wind, same as with this image, and is dryer, as seen here since it has no clouds. Abiotic cooling and heating are dependent on whether the parcel of air is increasing in altitude or decreasing in altitude. If a parcel is decreasing altitude, adiabatic warming is occurring. On the other hand, if a parcel is increasing altitude, the parcel is experiencing adiabatic cooling. How much a parcel cools or warms depends on where the air is moving in relation to the Lifting Condensation Level or LCL. The LCL is the dew point or where condensation begins for a parcel of air. If a parcel of air is below the LCL is will cool at the Dry Adiabatic Rate or DAR. Once the parcel or air hits the LCL, it will begin cooling at the Saturated Adiabatic Rate, or SAR. As a parcel of air rises it will cool at the DAR of 10 degrees Celsius per 1000 meters or 5.5 degrees Fahrenheit per 1000 feet. When the parcel hits the LCL, it will begin cooling at the SAR of 6 degrees Celsius per 1000 meters or 3.3 degrees Fahrenheit per 1000 feet.

For the question above, describe the evidence in the photograph that supports your answer. (Very Important: ensure that you use full sentences, without grammatical errors. Also, refer to the descriptions of particular types of mass wasting events in order to understand the characteristics of each type of event. The descriptions are in the Course Material notes for this lab exercise)

This image depicts a landslide. If you look at the notes for this lab, there is an example of a landslide. In both images, you can see parts of land having slid down in small particles. If you look at both images side by side it is very clear that they are depicting the same thing just with different types of land. The description of a landslide is the sliding of land down a mostly flat plane. In both images, there is a hill that is mostly flat and it is clear that the land has partially collapsed causing the sliding of the land down the hill. Thus this image depicts a landslide

For the question above, describe the evidence in the photograph that supports your answer. (Very Important: ensure that you use full sentences, without grammatical errors. Also, refer to the descriptions of particular types of mass wasting events in order to understand the characteristics of each type of event. The descriptions are in the Course Material notes for this lab exercise)

This image depicts a rockfall. The description of a rockfall is "the falling of loose pieces of rock down a very steep slope". In this image, there is a rock on a road. Surrounding the road are steep mountains. It is clear that the rock has fallen down the mountain to land on the road. That meets the description of a rockfall and thus the image is demonstrating that.

For the question above, describe the evidence in the photograph that supports your answer. (Very Important: ensure that you use full sentences, without grammatical errors. Also, refer to the descriptions of particular types of mass wasting events in order to understand the characteristics of each type of event. The descriptions are in the Course Material notes for this lab exercise)

This image depicts a slump. A slump is "the downslope rotational movement of a unit of weathered material along a curved plane". In the image, you can see that the plane depicted is curved, it is a small hill. It is clear that the top of it weathered and could no longer support the weight of the rest of the ground and the materials moved down the plane. This meets the criteria of a slump so that is what this picture shows

For the question above, describe the evidence in the photograph that supports your answer. (Very Important: ensure that you use full sentences, without grammatical errors. Also, refer to the descriptions of particular types of mass wasting events in order to understand the characteristics of each type of event. The descriptions are in the Course Material notes for this lab exercise)

This image depicts creep or soil creep. This is a process of particle-by-particle movement that is very slow. The surface material moves down a slope very slowly and it can be identified by objects on the hill leaning downslope. In the image, you can tell that the trees are definitely on a hill due to their elevation and the differing elevations of the different trees. In addition to this, the trees are leaning downslope, meeting the key sign of creep or soil creep, proving that the image is depicting that wasting process.

For the question above, describe the evidence in the photograph that supports your answer. (Very Important: ensure that you use full sentences, without grammatical errors. Also, refer to the descriptions of particular types of mass wasting events in order to understand the characteristics of each type of event. The descriptions are in the Course Material notes for this lab exercise)

This image depicts mudflow or debris flow. Mudflow is the movement down a mountain of high water fraction and rock fragments. When combined with large boulders it can be referred to as debris flow. This happens following a flash flood when materials are picked up and transported down a canyon, forming a deposit at the bottom. In this image, it is clear that mud has slid down the hill behind the cars and deposited in a large amount at the bottom of the hill. Due to a large amount of rain and how wet it looks, it appears to have been caused by a flash flood. Flash floods and large deposits of mud are signs of mudflow and that is why I believe that this image depicts mudflow.
