Weathering and Erosion by Cody Stenzel

What is Weathering?

Weathering breaks down rocks with climate change.

What is Erosion?

19stenzelco — 2015-01-22 16:02:22 UTC

It is when water, wind, and glaciers are used to move the rock and break the rock down.

What is Physical or Mechanical Weathering?

19schmidtna — 2015-01-22 16:05:38 UTC

Physical changes in temperature, freezing and thawing and the efects of wind, rain and waves.

Physical weathering by wind and water.

Rain and waves can wear the rock away over long periods of time.

Wind blows tiny grains of sand particales of the rock and hitting other rock busting them up too.

Erosion by wind.

Erosion by wind is when the wind pushes rocks and the hit other rocks and then the rocks move to a different location. Also wind can make sandstorms which moves rocks and breakes rocks down.

Erosion by water .(rivers,rain,oceans)

Erosion by water is when water hits the rock breaking it into small pieces and then that rock hits other rocks.

Physical weathering by ice wedging .

If water gets into the rock and freezes the rock will start to break because the water that is freezing starts to expand breaking the rock. The water than melts to form more ice that breaks the rock farther.

Erosion by glaciers.

Erosion by glaciers is when the glacier melts from the heat then flows into rocks. The water then freezes inside the rock, expanding the water which than breaking the rock.

Physical weathering by temperature changes

When water inside the rock frezzes it contracts and makes the rock get smaller and then easier to break apart.

What is Chemical Weathering?

19schmidtna — 2015-01-26 16:12:14 UTC

Chemical Weathering is a chemical reaction that occurs on the rock. This happens from the rain that creates the reaction.

Chemical weathering by acid rain

19stenzelco — 2015-01-26 16:12:38 UTC

Rain might fall into rocks starting a chemical reaction causing the rock to weather.

Chemical weathering by oxidation

19stenzelco — 2015-01-26 16:20:43 UTC

oxidation effects the rock because it makes the rock get rust which makes the rock able to be broken down.

The weathering by water and oxygen in iron-rich rocks giving the rock rust.

What is Biological weathering

19stenzelco — 2015-01-26 16:36:08 UTC

Biological weathering is when animals and plant life burrow or grow in side or cracks and rocks.

Biological weathering by plants

19stenzelco — 2015-01-26 16:36:58 UTC

When the roots in the plants get into the cracks of the rocks that are in the dirt well the roots start to expand whitch makes the rock get bigger.

Biological weathering by animals

19stenzelco — 2015-01-26 16:39:45 UTC

when an animal digs into the ground it sometimes can dig into an rock or break the rock whitch makes it weathered.

Biological Weathering By algae,liches,and mosses

19stenzelco — 2015-01-26 16:43:05 UTC

this make the rock get convirted into clay making it weathered.
