Weathering & Erosion

UNIT 4: WEATHERING, EROSION & MASS MOVEMENT

(LITHOSPHERE) 7 days

NC Standards

EEn.2.1.3 Explain how natural actions such as weathering, erosion (wind, water and gravity), and soil formation affect Earth's surface.
EEn.2.1.4 Explain the probability of and preparation for geohazards such as landslides, avalanches, earthquakes, and volcanoes in a particular area based on available data.
EEn.2.2.1 Explain the consequences of human activities on the lithosphere (such as mining, deforestation, agriculture, overgrazing, urbanization, and land use) past and present.
