Mountain – natural elevation of the earth’s surface with steep sides and greater height than a hill. Rift Valleys – tectonic plates pull away from each other causing the land (valley) in between to sink to a lower elevation than that of the other two plates. Erosion – material is removed by wind, water, ice, or gravity. Tectonic Forces – divergent, convergent (collision and subduction), and transform Delta – a triangular area of land formed from deposits at the mouth of a river Plateau – a broad, flat area of land higher than the surrounding land. Weathering – physical and chemical processes that change the characteristics of rock on or near the earth’s surface. Landform – naturally formed features of the surface of the earth. Strait – a narrow channel connecting tow larger bodies of water. CHAPTER 2 PAGE 26 REVIEW, REVIEW, REVIEW

What makes a MOUNTAIN? Converging of tectonic plates

What makes a MOUNTAIN? Converging of tectonic plates Continent to Continent Oceanic to Continent

What makes a PLATEAU? Weathering and Erosion

What makes a TRANSFORM FAULT? Diverging and converging that effects the surface

What makes a RIFT VALLEY? DIVERGING that effects the lithosphere

What makes a CANYON? Weathering and Erosion
