Water – It crashes into rocks and causes rocks to hit each other and become smaller and smoother. Copyright © 2010 Ryan P. Murphy

What happens if you leave a can of soda in the freezer?

Answer! It will explode because water expands when frozen. Copyright © 2010 Ryan P. Murphy

The increase in volume of ice is about 9%. Copyright © 2010 Ryan P. Murphy

The increase in volume of ice is about 9%. This increase causes enough force to break most rigid containers. Copyright © 2010 Ryan P. Murphy

The increase in volume of ice is about 9%. This increase causes enough force to break most rigid containers. This is the same force, repeated on a daily basis, that creates frost heaves in the roads in the winter. Copyright © 2010 Ryan P. Murphy

Ice/Frost Wedging: Water enters cracks in the rocks, freezes, expands and breaks rocks. Copyright © 2010 Ryan P. Murphy

Creates cracks and holds which you can use to rock climb. Copyright © 2010 Ryan P. Murphy

Effects of Animal Activity

Chemical Weathering This cave was formed by slightly acidic water dissolving the limestone Chemical weathering-occurs when chemical reactions dissolve the minerals in rocks or changes them into different minerals (rusting, acid breakdown, etc)

Chemical Weathering Natural Bridge Caverns in Texas

EROSION – the process by which natural forces move weathered rock and soil from one place to another. Forces that cause erosion: 1. Gravity 4. Waves 2. Wind 5. Running water 3. Glaciers

Erosion Galveston Texas before/after Hurricane Ike

Glacial Erosion Movement of Glaciers change the land beneath the glacier

Kelleys Island Glacial Grooves

Wind Erosion Shapes the land in areas where there are few plants to hold the soil in place (e.g. Desert)

Landslides Landslides- a geological phenomenon which includes a wide range of ground movement, such as rock falls, deep failure of slopes and shallow debris flows, which can occur in offshore, coastal and onshore environments.geological phenomenon

Deposition The process of eroded earth materials (sediments) being deposited in a new location Ex: delta-where sediment is deposited where a river flows into an ocean or lake builds up a landform Ex: sand dune-a deposit of wind blown sand

Deposition Desert winds sculpted these gentle swirls out of the limestone hills in Black Gap Wildlife Management Area, Texas. This remote, 100,000-acre (40,470-hectare) area in West Texas contains some of the lowest, driest, and hottest areas in the Chihuahuan Desert

Deposition Deposition area from the Rio Grande River The Red River carries sediments, and drops some along the way
