Weathering

• Weathering is the breaking down of rocks, soils,
  and minerals. Two important classifications about
  weathering processes exist physical and chemical
  weathering. The second classification chemical
  weathering has the direct effect of the
  atmospheric chemicals. Physical weathering is the
  process that disinigrates rocks. Frost weathering
  is the name for several processes where ice is
  present. Chemical weathering is a ongoing process
  as the mineralogy of the rock adjusts to the near
  surface environment. Biological weathering is the
  release acidifying molecules.

Erosion

• Erosion is the process by which soil and rock are
  removed from the earths surface, then brought
  and deposited somewhere else. Loosened soil by
  the surface runoff that is flowing in thin
  sheets. Wind erosion is a geomorphologic force.

What causes weathering and erosion

• Weathering is caused by elements of nature such
  as wind, rain, sleet, and snow. Heat is mostly
  the cause of chemical weathering. Causes of
  physical weathering are abrasion,
  crystallization, thermal insulation, wetting and
  drying, and pressure release. The cause of
  biological weathering are bacteria, to plants to
  animals.
• Erosion is caused by naturally on through
  artificial means. Water causes water erosion.
  Waves made by storms, winds, or fast moving motor
  craft cause coastal erosion. Gravity causes
  gravitational erosion. Wind erosion is caused by
  wind that picks up tiny particles and blows it
  into whatever is eroding.

5
The factors that control erosion

• The factors that control the rate of erosion are
  water, wind, and gravity

6
Soil erosion

• Soil erosion is the loss of soil by wind and
  water. Its a natural process. Soil shifts from
  one location to another.

Erosion in the southwest

• Erosion rates cape Shoal water have over 100 feet
  per year for a century. Erosion is cutting into
  the cape. 90 camp sites could be lost.

8
Wind erosion prevention

• Farmers will need to tillage the soil. Farmers
  will need to rotate the crops. Another way is to
  strip crop. Farmers can also try mulching the
  soil.

Landslides and mudflows

• Landslides happen when masses of rock move down a
  slope. Mudflow is downhill flowing mud.
