Earth Science
Plate Tectonics and Earth's Structure 1. Plate tectonics accounts for important features of Earth's surface and major geologic events. As a basis for understanding this concept: a. Students know evidence of plate tectonics is derived from the fit of the continents; the location of earthquakes, volcanoes, and mid-ocean ridges; and the distribution of fossils, rock types, and ancient climatic zones. b. Students know Earth is composed of several layers: a cold, brittle lithosphere; a hot, convecting mantle; and a dense, metallic core. c. Students know lithospheric plates the size of continents and oceans move at rates of centimeters per year in response to movements in the mantle. d. Students know that earthquakes are sudden motions along breaks in the crust called faults and that volcanoes and fissures are locations where magma reaches the surface. e. Students know major geologic events, such as earthquakes, volcanic eruptions, and mountain building, result from plate motions. f. Students know how to explain major features of California geology (including mountains, faults, volcanoes) in terms of plate tectonics. |

Lists of USGS Topographic Maps Illustrating Physiographic Features http://rockyweb.cr.usgs.gov/public/outreach/featureindex.html This web site provides a list of landscape features that can be found on topographic map. A simple query of the GNIS database (http://geonames.usgs.gov/pls/gnis/web_query.gnis_web_query_form) by the name of a topographic map will give you access to a map via http://www.topozone.com.
Topographic Salad-Tray Model http://geography.wr.usgs.gov/outreach/topo_instructions.html This basic activity-oriented lesson helps students to understand a topographic map by creating a three-dimensional model from contours on a topographic map. |

2a. Students know water running downhill is the dominant process in shaping the landscape, including California 's landscape. | ||||||||||||||||||
What's the Difference between Weathering and Erosion? http://wrgis.wr.usgs.gov/docs/parks/misc/gweaero.html This short discussion answers this commonly asked question... Weathering and Erosion in Desert Environments http://pubs.usgs.gov/of/2004/1007/erosion.html This web page explains how desert climates impact weathering and erosion processes (in the Mojave Desert). |

2b. Students know rivers and streams are dynamic systems that erode, transport sediment, change course, and flood their banks in natural and recurring patterns. | ||||||||||||||||||
Ground Water and Surface Water: A Single Resource (Circular 1139) http://water.usgs.gov/pubs/circ/circ1139/ This publication includes a chapter on the hydrologic cycle, and illustrates the interactions of groundwater and surface water. Large Floods in the United States : Where They Happen and Why (USGS Circular 1245) http://water.usgs.gov/pubs/circ/2003/circ1245/ This publication explains the nature of floods in the United States. The largest flows are related to specific combinations of regional climatology, topography, and basin size. Key factors include the general northward trend of decreasing atmospheric moisture, proximity to oceanic moisture sources such as the Pacific Ocean and the Gulf of Mexico, and orientation of topographic features relative to directions of moisture flow, with the largest flows being at locations where topographically high areas are oriented perpendicular to directions of moisture flow. Additionally, the largest flows in large river basins are primarily caused by persistent climatologic conditions such as seasonal snowfall. In contrast, the largest flows in smaller basins are most commonly the result of intense precipitation due to convective storms. |

2c. Students know beaches are dynamic systems in which the sand is supplied by rivers and moved along the coast by the action of waves. | ||||||||||||||||||
Coasts in Crisis (Circular1075) http://pubs.usgs.gov/circ/c1075/ This web site describes types of coasts (rocky shores, sandy beaches, coastal wetlands, and coral reefs). It also provides discussion about processes that affect beaches and coastlines including waves, tides, weather, water-level changes, coastal vegetation, and human impacts of beach sediments and processes. Beyond the Golden Gate: Oceanography, Geology, Biology, and Environmental Issues in the Gulf of the Farallones (Circular 1198) http://geopubs.wr.usgs.gov/circular/c1198/ The general report describes a major USGS geologic and oceanographic study of the Gulf of the Farallones. This investigation, the first of several now being conducted adjacent to major population centers by the USGS, was undertaken to establish a scientific data base for an area of 3,400 square kilometers (1,000 square nautical miles) on the Continental Shelf adjacent to the San Francisco Bay region. The results of this study can be used to evaluate and monitor human impact on the marine environment. |

2d. Students know earthquakes, volcanic eruptions, landslides, and floods change human and wildlife habitats. | ||||||||||||||||||
Surviving a Tsunami-Lessons from Chile, Hawaii, and Japan http://pubs.usgs.gov/circ/c1187/ This report describes actions that saved lives, and actions that cost lives, as recounted by eyewitnesses to the tsunami from the largest earthquake ever measured-the magnitude 9.5 earthquake in Chile on May 22, 1960. In interviews several decades later, people in Chile, Hawaii, and Japan recall the tsunami. West Coast & Alaska Tsunami Warning Center http://wcatwc.arh.noaa.gov/ This web site provides comprehensive information and links to information about earthquakes and related tsunami hazards for the West Coast and Alaska. It provides information about historic and recent tsunamis. Landslide Types and Processes (Fact Sheet) http://pubs.usgs.gov/fs/2004/3072/fs-2004-3072.html This fact sheet (web site) provides a basic overview of various kinds of landslides. Landslide Hazards http://pubs.usgs.gov/fs/fs-0071-00/fs-0071-00.pdf This web site provides basic information about landslide hazards and safety issues related to wet weather conditions in landslide-prone areas. National Landslide Hazards Mitigation Strategy: A Framework for Loss Reduction (Circular 1244) http://pubs.usgs.gov/circ/c1244/ This circular outlines the key elements of a comprehensive and effective national strategy for reducing losses from landslides nationwide and provides an assessment of the status, needs, and associated costs of this strategy. Large Floods in the United States : Where they Happen and Why (Circular 1245) http://water.usgs.gov/pubs/circ/2003/circ1245/ This on-line publication describes the geographic factors that influence the occurrence and impacts of large floods in the United States. |

Energy in the Earth System4. Many phenomena on Earth's surface are affected by the transfer of energy through radiation and convection currents. As a basis for understanding this concept:a. Students know the sun is the major source of energy for phenomena on Earth's surface; it powers winds, ocean currents, and the water cycle. b. Students know solar energy reaches Earth through radiation, mostly in the form of visible light. |

Ecology (Life Science)5. Organisms in ecosystems exchange energy and nutrients among themselves and with the environment. As a basis for understanding this concept:a. Students know energy entering ecosystems as sunlight is transferred by producers into chemical energy through photosynthesis and then from organism to organism through food webs. b. Students know matter is transferred over time from one organism to others in the food web and between organisms and the physical environment. c. Students know populations of organisms can be categorized by the functions they serve in an ecosystem. d. Students know different kinds of organisms may play similar ecological roles in similar biomes. e. Students know the number and types of organisms an ecosystem can support depends on the resources available and on abiotic factors, such as quantities of light and water, a range of temperatures, and soil composition. |
