Beeson Explosion structures occur in flows of Grande Ronde Basalt in the study area near Troy, Oregon. Data from nineteen stratigraphic sites indicate that the maximum number of flows that contain explosion structures at any one site is six. In the informally named Troy flow, explosion structures are widespread. Each flow that contains explosion structures can be divided into two cooling units. The first cooling units occupy troughs in the pre-eruption topography and are up to 10 meters thick.

  • Class Assignment Key Word Search on Weathering I. Physical
    ES322 Geomorphology - Class Assignment Key Word Search on Weathering I. Physical Weathering The process in which rocks are eroded and broken down into smaller rocks by natural physical processes such as wind, water, ice, plants, gravity, and climate. The type of a. Exfoliation Rock is buried (ex: Lava chamber or Batholith cools underground) Overtime land above is eroded as tectonic uplift pushes rock up. The rock becomes exposed and flakes off in layers as the overburden of soil and tremendous pressures the rock experienced at the depths in which it formed are lifted. The rock is composed of deep hot lava rocks that are not as stable at the earth's surface and as such are more susceptible to erosion. b. Freeze-Thaw Changing climate throughout the year (ideally that of the 45th parallel) produces conditions whereby rocks freeze and thaw in a relatively wet environment. As rain falls it percolates down through tiny cracks and fractures in the rock and stays there as temperatures drop in the winter and freezes. Due to the density of water compared to ice, the ice expands in volume as it freezes increasing the pressure inside the cracks and expanding them. As this persists the effect is exponential whereby more cracks are formed allowing more water to intrude in and freeze, eventually breaking down the rock. c. Thermal Expansion PV=NRT or the ideal gas law can be used to explain thermal expansion. As the temperature goes up, so must the pressure of the gas on its container or, if the gas is uncontained, higher temperatures result in higher volumes or greater gas diffusion.

    IUCN World Heritage Outlook: https://worldheritageoutlook.iucn.org/ Göreme National Park and the Rock Sites of Cappadocia - 2014 Conservation Outlook Assessment (archived) IUCN Conservation Outlook Assessment 2014 (archived) Finalised on 21 May 2014 Please note: this is an archived Conservation Outlook Assessment for Göreme National Park and the Rock Sites of Cappadocia. To access the most up-to-date Conservation Outlook Assessment for this site, please visit https://www.worldheritageoutlook.iucn.org. Göreme National Park and the Rock Sites of Cappadocia INFORMACIÓN DEL SITIO Country: Turkey Inscribed in: 1985 Criteria: (i) (iii) (v) (vii) In a spectacular landscape, entirely sculpted by erosion, the Göreme valley and its surroundings contain rock-hewn sanctuaries that provide unique evidence of Byzantine art in the post-Iconoclastic period. Dwellings, troglodyte villages and underground towns – the remains of a traditional human habitat dating back to the 4th century – can also be seen there. © UNESCO RESUMEN 2014 Conservation Outlook Good with some concerns The conservation outlook for Göreme National Park and the Rock Sites of Cappadocia is good with some concerns regarding excessive tourism impacts on the site. Göreme’s natural beauty was comparatively well preserved at the time of its inscription, however construction activities to accommodate the ever growing number of tourists visiting the site has put pressure on its scenic value. The provision of hotels and services for these visitors tended to overwhelm the park and surrounding villages in the absence of a management plan and trained park personnel. The growing awareness among the stakeholders, both public and private, is leading to better protection of the natural beauty of the Göreme Valley and its surroundings.
