Grade 5 Curriculum Overview SS
Social Studies: 5th Grade Curriculum Overview North American Geography OVERVIEW: The standards in fifth grade focus student learning on the geography of North America. The introductory unit is designed to familiarize students with the many different tools and themes that geographers use to study the world. Students are introduced to some of the unique physical characteristics of the continents as they create their mental maps of the world. The skills and concepts introduced will continue to be practiced and refined as students study North America. Using these skills and the five 5th themes of geography, students will study five United States regions, Canada, Mexico, Central America, and the Caribbean Islands. Students will be able to compare and contrast the physical, cultural, and economic geography of regions and countries in North America. Sites that represent the cultural characteristics of each region provide students with a sense of what life in the region is like today. Regional Studies Essential Skills StudentsNAG will practice 5.3-5.9 and apply the following skills throughout the course: • Interpret a map legend (key) and a map scale to help understand information contained on a map. •The studentAnalyze will and explore interpret maps. •regionsAnalyze of the andUnited interpret graphs, charts, tables, and images of geographic information. •StatesInterpret and countries a model of of the earth showing the locations of the continents, oceans, equator, and prime meridian. •North AmericaDescribe theby: location of a continent by determining the hemisphere(s) where it is located. • Explain the use of GPS. •a. locatingCompare the regionand contrast on places using the five themes of geography. -

Historical Fire Regime Patterns in the Southwestern United States Since AD 1700

Historical Fire Regime Patterns in the Southwestern United States Since AD 1700 Thomas W. Swetnam and Christopher H. Baisan1 Abstract.-Fire-scar chronologies from a network of 63 sites in the South western United States are listed and described. These data characterize the natural range and variability of fire regimes from low elevation pine forests to higher elevation mixed-conifer forests since AD 1700. A general pattern of increasing length of intervals between low intensity surface fires was observed along gradients of low to high elevations, and from the rela tively drier pine sites to the wetter mixed-conifer sites. However, large vari ability in the measures of central tendency and higher moments of the fire interval distributions suggest that elevation and forest type were often weak determinants of fire frequency. Some of the variations in fire interval distri butions between similar elevation or forest types were probably due to unique site characteristics, such as landscape connectivity (Le., ability of fires to spread into the sites), and land-use history. Differences in the sizes of sampled areas and fire-scar collections among the sites also limited our ability to compare and interpret fire interval summary statistics. Comparison of both the fire-scar network data (1700 to 1900) and docu mentary records of area burned on all Southwestern Region National For ests (1920 to 1978) with a Palmer Drought Severity Index time series clearly shows the association between severe droughts and large fire years, and wet periods and small fire years. -

236 Pinaleño Mountains in the Twentieth Century Atalanta Hoyt
Pinaleño Mountains in the Twentieth Century Atalanta Hoyt Throughout the twentieth century, a few major events dominated the history of the Forest Service. First, the founding of the National Forest Service in 1905 replaced the Bureau of Forestry and led to the creation of modern National Forests. The new service was created under the jurisdiction of the Department of Agriculture with the purpose of securing a long term supply of timber for the American people.1 Second, the great depression of the 1930s, Franklin Roosevelt’s creation of the Civilian Conservation Corps (CCC) and the expansion of the Forest Service changed the shape of National Forests.2 This time period featured a major transition from timber management to hands on putting resources into the forest. The Forest Service and CCC planted trees, carved trails, built roads, and conducted research; actively molding forests and applying the latest forestry techniques instead of letting the forest take its course.3 A third period of great change came in the 1970s during the environmental era.4 The emphasis changed from conceptualizing the forests as resources to be converted into marketable goods to seeing them as wilderness in need of preservation. While conservation has always been an important part of the Forest Service - advocated by both those who saw an intrinsic value in wilderness and by those who used the wilderness for recreational purposes - increased urbanization highlighted the uniqueness of forests. Efforts to catalog and protect the environments of forests became a main priority while ecologists and conservationists gained status.5 These three main shifts defined the Forest Service in the twentieth century. -

Controls on Geothermal Activity in the Sevier Thermal Belt, Southwestern

Central Campus Dr., Salt Lake City, UT 84112 3Utah Geological Survey, 1594 W. North Temple St., Salt Lake City, UT 84114 [email protected] Keywords: Sevier Thermal Belt, hydrothermal systems, heat flow, geochemistry, helium isotopes, stable isotopes. ABSTRACT The Sevier Thermal Belt, southwestern Utah, covers 20,000 km2, and it is located along the eastern edge of the Basin and Range, extending east into the transition zone of the Colorado Plateau. The belt encompasses the geothermal production fields at Cove Fort, Roosevelt Hot Springs, and Thermo, scattered hot spring activity, and the Covenant & Providence hydrocarbon fields. Regionally, it is characterized by elevated heat flow, modest seismicity, and Quaternary basalt-rhyolite magmatism. There are at least five large discrete domains (50 to >500 km2) with anomalous heat flow, including ones associated with Roosevelt Hot Springs, Cove Fort, Thermo and the Black Rock desert. Helium isotope data indicate connections to the upper mantle are developed over the region of strongest and most concentrated hydrothermal activity. By contrast, stable isotope data demonstrate that most of the convective heat transfer is associated with shallow to deep circulation of local meteoric water. Quartz-silica geothermometry suggests that convective heat transfer is compartmentalized by stratigraphic horizons and sub-vertical faults. -
Chapter 3 of the State Wildlife Action Plan
Colorado’s 2015 State Wildlife Action Plan Chapter 3: Habitats This chapter presents updated information on the distribution and condition of key habitats in Colorado. The habitat component of Colorado’s 2006 SWAP considered 41 land cover types from the Colorado GAP Analysis (Schrupp et al. 2000). Since then, the Southwest Regional GAP project (SWReGAP, USGS 2004) has produced updated land cover mapping using the U.S. National Vegetation Classification (NVC) names for terrestrial ecological systems. In the strictest sense, ecological systems are not equivalent to habitat types for wildlife. Ecological systems as defined in the NVC include both dynamic ecological processes and biogeophysical characteristics, in addition to the component species. However, the ecological systems as currently classified and mapped are closely aligned with the ways in which Colorado’s wildlife managers and conservation professionals think of, and manage for, habitats. Thus, for the purposes of the SWAP, references to the NVC systems should be interpreted as wildlife habitat in the general sense. Fifty-seven terrestrial ecological systems or altered land cover types mapped for SWReGAP have been categorized into 20 habitat types, and an additional nine aquatic habitats and seven “Other” habitat categories have been defined. SWAP habitat categories are listed in Table 4 (see Appendix C for the crosswalk of SWAP habitats with SWReGAP mapping units). Though nomenclature is slightly different in some cases, the revised habitat categories presented in this document
