♡Explain how the following agents causes weathering of rocks to form soils.
☆plants and animals/ biological organisms(physical weathering)
☆Rain water(chemical weathering)
Answers
Plants and animals release acid ... caused by breaking down of rocks ... agent of chemical weathering is. Page 2. rainwater. Chemical weathering, such as acid rain, eats away at.
Answer:i) Biological weathering is weathering caused by plants and animals. Plants and animals release acid forming chemicals that cause weathering and also contribute to the breaking down of rocks and landforms. or//
Mechanical or physicalweathering involve-s the breakdownof rocks and soils through direct contact with atmospheric conditions, such as heat, water, ice and pressure. ... The materials left over after the rock breaks down combined with organic material creates soil.
ii) chemical weathering caused by rain water. Rain has a major impact on karst scenery through chemical weathering. 'Ordinary' rain is naturally acidic because it contains dissolved carbon dioxide that forms weak carbonic acid. When this weak acid comes into contact with calcite, the limestone begins to dissolve. or//
ChemicalWeatheringMajor chemical reactions include carbonation, dissolution, hydration, hydrolysis, and oxidation-reducation reaction. All of these reactions have water involved with them. ... Oxidation-Reduction - water and rock particles react with oxygen. This causes the minerals and materials to rust and turn red.hope it is helpful to you god keep u happy always
