Water Cycle Revisited

Question Explain evaporation, precipitation, and condensation

Water Important –We need it It can be very damaging –Destroy

Erosion vs. Weathering Erosion –Breakdown AND movement Weathering –Breakdown of material

Two Types of Weathering Mechanical – break down by physical means –Abrasion –Organic activity Chemical – break down by chemical reactions –oxidation

Rates of Weathering Some material erode faster –Depends on softness/hardness How much is exposed –Surface area Location –Climate –Topography/Elevation

Wind Erosion Wind can also erode Moves loose fragments of dirt/dust –Areas where plant roots do not anchor soil as well

EROSION Creates many features You and a partner will learn about 1 and describe it to the class

Erosion Landforms Gullying and Sheet Erosion Rockfalls and Landslides Mudflows and Slumps Solifluction Creep Erosion of Mountains Erosion of Plains and Plateaus Channel Erosion Braided Stream Caverns Sinkhole & Natural Bridges Karst Topography Landforms Created by Glacial erosion (cirque, arête, horn) Kettle Glacial Lake Deflation Dune Sea Caves, Arches, and Stacks Sea Cliffs Terraces Beaches Berm
