Weathering and soil formation – section 2-1 Rocks and Weathering B A Mechanical weathering, chemical weathering Mechanical Freezing and thawing, release of pressure, growth of plants, actions of animals, abrasion Grinding away of rock by other rock particles carried in water, ice, or wind Chemical Water, oxygen, carbon dioxide, living organisms, and acid rain False C D E true

Oxidation Marble, limestone Plants dissolve rock by producing weak acids around their roots. Climate True Permeable As water seeps through the spaces in the rock, it removes dissolved material formed by weathering. It occurs more quickly because chemical reactions occur faster at higher temperatures.
