Biological weathering is caused by living organisms, such as microbes, animals, and plants. Water, oxygen, and rocks are nonliving things (though water and rocks may be capable of weathering), and only plant roots fits the definition of biological weathering. So the correct answer for #1 is A.
Frost wedging occurs when the little water content in rock freezes, expanding and forcing the rock apart. Eventually, enough freeze-melt cycles causes the rock to break apart little by little. This is due to ice's density being less than that of water, meaning that it is because water expands when frozen. So the answer to #2 is A.
The right answer for the question that is being asked and shown above is that: "(3) absorb less insolation and reflect more insolation." Compared to a light-colored rock with a smooth surface, a dark-colored rock with a rough surface will absorb less insolation and reflect more <span>insolation</span>
