Goal 2.1.3

EEn.2.1.3 Explain how natural actions such as weathering, erosion (wind, water and gravity), and soil formation affect Earth’s surface.

Weathering http://www.ux1.eiu.edu/~cfjps/1300/weathering.html Mechanical/physical chemical http://www.classzone.com/books/earth_science/terc/content/visualizations/es1201/es1201page01.cfm?chapter_no=visualization http://www.geolsoc.org.uk/ks3/gsl/education/resources/rockcycle/page3564.html

Erosion: movement of rocks and sediment http://www.geography4kids.com/files/land_erosion.html Factors: gravity, water, wind

Soil Made of particles of rocks and minerals, organic matter, water, and air Water moves slowly through smaller, more tightly packed sediments (like clay)
