L1.3: Factors that Affect Weathering

• Factors that Affect Weathering

  ● Climate

  ● Rock Type

  ● Rock Structure

  ● Topography

  ● Time
• ● Climate

  ○ Areas that are cold and dry tend to have slow rates of chemical weathering and the type is mostly physical. On the other hand, chemical weathering is most active in areas with high temperatures and rainfall.

  ○ Simplified: If less yung ulan (dry) and malamig mas discernible yung physical. Pero kapag maulan naman and mas mainit mas evident yung chemical.
• ● Topography

  ○ Physical weathering occurs more quickly on a steep slope than on a gentle one. On a gentle slope, water may stay longer in contact with the rocks, hence chemical weathering is enhanced..

  ○ Mas matarik mas enhaced yung physical weathering. Gentle slope naman prolongs yung water kasi it can’t roll down and stuff
• ● Time

  ○ Length of exposure to agents of weathering determines the degree of weathering of rock.
