    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.

  • Spatial Variability of Levees As Measured Using the CPT
    2nd International Symposium on Cone Penetration Testing, Huntington Beach, CA, USA, May 2010 Spatial Variability of Levees as Measured Using the CPT R.E.S. Moss Assistant Professor, Cal Poly, San Luis Obispo J. C. Hollenback Graduate Researcher, U.C. Berkeley J. Ng Undergraduate Researcher, Cal Poly, San Luis Obispo ABSTRACT: The spatial variability of a soil deposit is something that is commonly discussed but difficult to quantify. The heterogeneity as a function of lateral distance can be critical to the design of long engineered structures such as highways, bridges, levees, and other lifelines. This paper presents a methodology for using CPT mea- surements to quantifying the spatial variability of cone tip resistance along a levee in the California Bay Delta. The results, presented in the form of a general relative va- riogram, identify the distance at which the maximum spatial variability is achieved for a given soil strata. This information helps define minimally correlated stretches of levee for proper failure and risk analysis. Presented herein are methods of interpret- ing, calculating, and analyzing CPT data to arrive at the quantified spatial variability with respect to different static and seismic failure modes common to levee systems. 1 INTRODUCTION Spatial variability of engineering properties in soil strata is inherent to the nature of soil. Spatial variability is controlled primarily by the depositional environment where high energy systems usually deposit materials with high spatial variability (e.g. al- luvial gravels) and low energy systems usually deposit materials with low spatial va- riability (e.g. lacustrine clays). This spatial variability is generally taken into account in geotechnical design in a qualitative empirical manner through appropriately spaced borings to assess the changing subsurface conditions.

  • The Tectonic Evolution of the Madrean Archipelago and Its Impact on the Geoecology of the Sky Islands
    The Tectonic Evolution of the Madrean Archipelago and Its Impact on the Geoecology of the Sky Islands David Coblentz Earth and Environmental Sciences Division, Los Alamos National Laboratory, Los Alamos, NM Abstract—While the unique geographic location of the Sky Islands is well recognized as a primary factor for the elevated biodiversity of the region, its unique tectonic history is often overlooked. The mixing of tectonic environments is an important supplement to the mixing of flora and faunal regimes in contributing to the biodiversity of the Madrean Archipelago. The Sky Islands region is located near the actively deforming plate margin of the Western United States that has seen active and diverse tectonics spanning more than 300 million years, many aspects of which are preserved in the present-day geology. This tectonic history has played a fundamental role in the development and nature of the topography, bedrock geology, and soil distribution through the region that in turn are important factors for understanding the biodiversity. Consideration of the geologic and tectonic history of the Sky Islands also provides important insights into the “deep time” factors contributing to present-day biodiversity that fall outside the normal realm of human perception. in the North American Cordillera between the Sierra Madre Introduction Occidental and the Colorado Plateau – Southern Rocky The “Sky Island” region of the Madrean Archipelago (lo- Mountains (figure 1).

Nacional Auto´noma de Me´xico (UNAM), Apartado postal 70-399, 04510 Mexico, D.F., Mexico. B IOGEOGRAPHIC Transition zones, located at the boundaries between biogeographic regions, represent events of biotic hybridization, promoted by historical and ecological changes. They deserve special attention, because they represent areas of intense biotic interaction. In its more general sense, the Mexican Transition Zone is a complex and varied area where Neotropical and Nearctic biotas overlap, from southwestern USA to Mexico and part of Central America, extending south to the Nicaraguan lowlands. In recent years, panbiogeographic analyses have led to restriction of the Mexican Transition Zone to the montane areas of Mexico and to recognize five smaller biotic components within it. A cladistic biogeographic analysis challenged the hypothesis that this transition zone is biogeographically divided along a north-south axis at the Transmexican Volcanic Belt, as the two major clades found divided Mexico in an east-west axis. This implies that early Tertiary geological events leading to the convergence of Neotropical and Nearctic elements may be younger (Miocene) B than those that led to the east-west pattern (Paleocene). The Mexican Transition Zone consists of five biogeographic OUNDARIES provinces: Sierra Madre Occidental, Sierra Madre Oriental, Transmexican Volcanic Belt, Sierra Madre del Sur, and Chiapas.
