Mountains Rift Valleys Erosion

Tectonic Forces

Delta Plateau

Weathering Landform Strait

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 transformDelta – a triangular area of land formed from deposits at the mouth of a riverPlateau – 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.
