Did you know that WATER is the main reason for chemical weathering]]> 2018-01-28 19:54:35 UTC https://padlet.com/mary_ayers/udaxeyoq6ftj/wish/225426581 mary_ayers https://padlet.com/mary_ayers/udaxeyoq6ftj/wish/225427233 A type of weathering that causes the weakening of rock by plants, animals and microbes. Growing plant roots can exert stress or pressure on rock. Although the process is physical, the pressure is exerted by a biological process (i.e., growing roots).
