Heat from the sun evaporates water from oceans, lakes, and streams. Although most of the water returns directly as precipitation to the oceans, some of the water is recipitated over land as rain or snow. If it is precipitated over land, it then begins its journey back to the sea as "runoff." The relentless action of surface runoff, streams, and rivers, glaciers, and waves sculpts the rock into intriguing and bizarre shapes. This set of slides includes examples of wave erosion, wind and water erosion, valley shapes, and glacial rosion. The views are often dramatic. Many were taken at U.S. National Parks and Monuments.To provide long-term scientific data stewardship for the Nation's geophysical data, ensuring quality, integrity, and accessibilityIn workasNeeded0000NASA/GCMD Earth Science KeywordsEARTH SCIENCE > HUMAN DIMENSIONS > Natural Hazards > Geological HazardsRestriction Code: otherRestrictions; DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of CommerceHazards Dataphysical and mailing NOAA/NESDIS/NGDC E/GC 325 Broadway BoulderCO80305-3328(303) 497-3707haz.info@noaa.govUnknown 20120222Heather McCulloughDOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commercemailing and physical NOAA/NESDIS/NGDC/MGG 325 Broadway E/GC3 BoulderCO80305-3328(303) 497-3707haz.info@noaa.govHeather.McCullough@noaa.govContent Standard for Digital Geospatial Metadata: Extensions for Remote Sensing MetadataFGDC-STD-012-2002
