Weathering and Erosion

Acid rain is a direct result of

• Pollution

• Oxidation

• Rain

• Weathering

The process of moving sediment away from where it was created

• Deposition

• Erosion

• Weathering

• I like to move it Move it!

Type of chemical weathering breaks down rock using water and oxygen

• Lichens

• Acid Rain

• Oxidation (rust)

• Dissolving

How do waves cause weathering?

• Acids in water

• It carrys rocks that grind and wear away the shoreline

• Waves are like big sheets of ice that drag and dip rock and move them

• The wind picks up sand and silt and blows them onto the waves

Why do river rocks become rounded?

• The current makes them tumble against each other

• acid rains melts the edges off

• Water freezes and breaks the edges off

• Ocean waves bread down the edges

Why do rocks on the side of mountains fall?

• Chemical weathering

• mass wasting (gravity)

• waves

• Glaciers

What is this landform

• Sand dune

• Rock Cliff

• Glacier

• Weathering

How was this landform created?

• High tides

• Wind

• Humans

• Rivers

Eventually rocky cliffs will become smaller and smaller. Which process causes this?

• Erosion

• Deposition

• Weathering

• Evaporizationinglyness

Over-grazing ( eating too much) of cattle can cause what?

• Soil will become more fertile

• Grass will grow faster

• Soil will be eroded away by wind and water

• soil will become water soaked in the spring
