How can biologic weathering result in chemical erosion? roots loosen soil and break rocks

plants transpire water vapor

large herds trample rocks and break up soil

bacteria release acids and other agents that break down rock

roots loosen soil and break rocks

Explanation:

Plants and animals release acid forming chemicals that cause weathering and also contribute to the breaking down of rocks and landforms.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
